Gardening with Grower Direct
Native Alberta Plants
Gardening can sometimes be defined as cultivating species of Flowers,
vegetables or trees that do not commonly occur in your back yard. The
challenge is often to find plants that will survive our Canadian winters
and the rigours of our back yard environments including drought or shade.
When you use plants native to your area you can eliminate many of the
hazards of gardening, because you can be sure the plants will be cold
tolerant and definitely hardy in your conditions. The only challenge with
growing native plants, then, would be to choose the varieties and species
that best suited your needs for colour, fragrance, shade or growth habit.
It is often the case that native plants grown under the more generous
and fertile conditions of the home garden will produce longer stems, larger
and more numerous Flowers and be much more beautiful than they were in
their original locations.
Provenance
True native plant enthusiasts can be very particular about the "provenance"
of a species. This is the geographic area that a species occupies in the
wild. If you could compare the genetics of a yarrow plant from the Edmonton
area and a yarrow plant from Nelson BC, you would see that there are significant
differences in their genetic codes. For the purists, bringing that yarrow
plant from BC to plant in an Edmonton garden would be polluting the gene
pool of the Edmonton yarrow plants. The Edmonton yarrow has provenance
over it's geographic location in a circle about 100 km wide.
For many gardeners, the idea of provenance is too restricting and they
choose plants from far away locations on purpose. It is still valid to
grow a Brown Eyed Susan from southern Alberta in your Edmonton garden,
but you're not really following the rules of true native plant gardening.
Despite the purists, however, there are thousands of species of plants
growing wild in many different ecosystems across Alberta that will thrive
in the home garden and bring you many years of pleasure. If at all possible,
try to use plants and seeds from local sources. This is especially important
in large plantings and for restoration or reclamation projects.
Starting Plants
If you want to start your own native plant garden or use some native
plants in your existing landscape, you can find source materials in your
nearby forest or roadside. There is an environmental problem with collecting
seeds or plants from the wild, however, so be sure to follow the rules.
1. You should never dig up a plant from the wild to transplant to your
garden. The only exception to this would be if the area was slated to
be bulldozed for a road or dam site or other non environmentally friendly
activity. Often, these transplanted plants don't survive the move anyway,
as they are not acclimated to your garden conditions. You are much better
off to start your own plants from seeds so that they are well conditioned
to your garden and your style of gardening.
2. Collecting seeds for propagation is much more environmentally friendly
than digging up plants. Never collect more than 1/10 of any stand of seeds.
The remainder of the seeds are for the perpetuation of the species in
the wild, and for the animals and insects to consume.
Species Selection
Deciding which species or families of plants to look for can be the hard
part, as well as the most entertaining part. Your best resource will be
a good field guide on native plants of Alberta. Choose one with clear
photographs or line drawings and descriptions of a broad range of plants
so you can become familiar with the wide variety of plants you will no
doubt encounter on your search.
Often you can narrow the selection criteria by defining an ecosystem
you wish to copy or create in your back yard. A dryland rock garden could
include native Opuntia cactus (Opuntia polyacantha), Dotted Blazing Star
(Liatris punctata), and maybe some Creeping Juniper (Juniperus horizontalis).
A boreal forest habitat could include the beautiful blue lungwort (Mertensia),
Shining Arnica (Arnica fulgens), and Giant Anise Hyssop (Agastache foeniculum).
Of course you can always just add native plants to your existing landscape
design, without trying to recreate a whole ecosystem. Keep in mind where
the plants grow naturally to guide you on the best placement of these
beauties in your yard.
Here's a list of native Alberta wildFlowers that would be easy to find
and easy to cultivate in the garden.
ANNUALS
Brown Eyed Susan. Rudbeckia hirta
Bright yellow petals surrounding a dark brown or black centre on 30 cm
stems. Easy from seed and will self sow. Can even get invasive in a small
garden. This species is very good for acreage wild Flower gardens where
you want to establish wildFlowers over a large area. Flowers in mid summer.
Great Flowered Gaillardia. Gaillardia aristata
Similar to brown eyed susans, but the petals are yellow with bright red
or orange marks in the centre. Easy from seed.
Fireweed. Epilobium angustifolia
Tall, to 1 m, spikes of purple Flowers in mid to late summer. Very attractive
to bees and butterflies. Fireweed has some medicinal properties as well.
This is another invasive plant and will spread rapidly from year to year
under the right conditions. It does best in partial shade, and will produce
shorter stems in full sun.
PERENNIALS
Start perennials from seed any time from April to October. You can also
start them indoors in March, but this seems like more trouble than necessary
when they are so easy to start outdoors. Many native plants, both annuals
and perennials do best when seeded in the fall. This gives them a cold
treatment over the winter and they germinate very well the following spring.
Just be careful to keep them in trays or pots, or in a clearly marked
spot in the garden so you will find them again in the spring.
Anemone
This is a large family with many interesting members. Anemone patens is
the well know purple prairie crocus that blooms early in the spring and
Anemone canadensis the Canada anemone is a very pretty white Flower on
20 cm stems, very good for full or partial shade.
Asters
Again, this is a big family with many interesting Flowers, mostly Flowering
late in the summer and fall. The common blue aster (Aster laevis), has
purple petals around a yellow centre, on tall 30 - 35 cm stems. Aster
pansus has a multitude of white Flowers with yellow centres on 20 - 25
cm stems.
Buffalo Beans
Thermopsis rhombifolia. This is a low growing (10 - 15 cm) legume producing
bright yellow pea like Flowers in early summer. This is a good candidate
for naturalizing in a lawn or grassy wild area.
Clematis.
Clematis ligusticifolia (White) and Clematis columbiana (Purple) are very
attractive vines that are very hardy and fast growing. Try them along
a fence, up a tree, or trailing down a stone wall. They can be growing
from cuttings, but usually seeds are easier.
Fleabane. Erigeron spp
There are many members of this family also. They produce daisy like Flowers,
similar to the aster, but they come in a wider range of colours including
pinks and yellows. Usually shorter stems to 25 cm. Easy from seed.
Giant Anise Hyssop. Agastache foeniculum
This is a spectacular plant in the landscape, producing spikes of blue
Flowers on tall 50 - 60 cm stems. The blooms stay coloured for months
and are particularly attractive to bees and butterflies. It is said to
produce very good honey. The licorice flavoured leaves can be used in
desserts and teas. Very easy from seed, cuttings or root divisions, this
plant will develop into a large clump within a few years. It prefers partial
shade but does very well in full sun too. A striking addition for the
back of the perennial border or at the edge of the trees.
Goldenrod. Solidago canadensis
For some people Goldenrod is too much like a weed to be able to enjoy
it in the garden. For large gardens or acreage wild Flower fields, it
makes an excellent late summer bloomer with bright yellow plumes that
last for weeks. Easy from seed. It is persistent and will form large clumps
over time. Goldenrod is often found growing alongside Aster laevis. They
Flower at the same time and they look very attractive together, the purple
aster contrasting well with the yellow goldenrod.
Lemon Mint. Monarda fistulosa
This is a very attractive plant, fragrant, colourful and easy to grow.
It will grow to 40 cm in the shade, and only 10 cm in full sun. A member
of the mint family, it spreads slowly from root stolons and may also self
seed. It is very attractive to bees and butterflies and can even attract
hummingbirds to the larger plants. The herb is used for a pleasant lemon
flavoured tea. Easy from seed.
Indian Paintbrush. Castilleja spp
There are several species of paintbrush, ranging from yellow, red and
even pink tops. The colour comes from the leafy structures at the top
of the stem while the actual Flowers are very tiny and buried inside the
leaves. The seed is also very small and difficult to germinate. There
has been some thought that the plants require a host/symbiont relationship
with another plant species, perhaps a tree or grass species growing in
close proximity so that their roots inter twine. This has not been proven,
however, and some growers have successfully produced paintbrush in containers.
The tiny seed is a problem, however, and this species is not recommended
for novice gardeners. Best results are from sprinkling the seed on very
fine moist peat, cover with plastic and hold at 15 - 20 C until germination.
Prickly Pear Cactus. Opuntia polyacantha
This is one of Alberta's native cactus, commonly found near Drumheller
and south to the Cypress Hills. It has flat, broad "stems" covered
with spikes (leaves) and will produce bright yellow Flowers in early spring.
Moderately easy from seed and very persistent once started. Keep in a
sunny, dry location.
Western Wood Lily. Lilium philadelphicum
This is the common tiger lily. Easy from seed. Do not collect plants from
the wild!! It can even be bad to collect seed from the wild unless you
find an especially large stand of this. The plant is in serious decline
because of it's popularity with gardeners and wild Flower "pickers".
Once started, however, it will bloom prolifically and last for many years.
It prefers slightly shaded locations but will grow in full sun. Do not
cut the Flowers as this removes much of the carbohydrate energy supply
to the bulb and reduces the vigour of the bulb to a point where it often
does not recover.
Yarrow. Achillea millefolium (Many
Flowered Yarrow) the common variety.
Achillea ptarmic (Bridal Veil,
Pearl Yarrow)
Larger Flowers, dark green leaves. Achillea sibirica similar to A. millefolium,
but with larger Flower heads. All of the yarrows are very easy to grow
from seed. Fall planting is best as a cold period helps germination. They
will self sow and can be invasive, although this characteristic makes
them very good in large wildFlower plantings.
Pearl Yarrow
Is by far the most attractive, with large white Flowers. A. millefolium
can be purchased as a garden plant in various pastel shades from pink,
peach, mauve and red, however, the native yarrow is almost always white,
although occasionally you may find a slightly pink one.
TREES AND SHRUBS
There are many beautiful and varied native woody plants for your home
landscape as well. Again, these plants wood be more hardy, cold and drought
tolerant, and more resistant to pests and diseases than their imported
relatives. The range includes prostrate, ground huggers, shrubs, trees
and even vines. Many have Flowers or fruit too.
Saskatoon Berry Amelanchier alnifolia
This is the well known prairie staple, great for pies, jams and almost
everything else. Get a small plant to start, Saskatoon bushes will creep
underground so give them a wide area to fill or be prepared to keep them
pruned to contain them.
Dwarf Birch Betula glandulosa
This is a very nice, tall shrub with dark, glossy green leaves and an
attractive upright habit. Good in shade or wet areas.
Paper Birch Betula papyrifera
This well known birch is valuable for it's beautiful white stems which
will look great in contrast with green evergreens or red dogwood. Easy
to grow, likes extra watering in the heat of summer and going into fall.
Dogwood. Cornus stolonifera
The red twigs of dogwood make it an especially attractive part of the
winter landscape. Plant it next to green evergreens or a white painted
wall. Try growing this from cuttings taken from thin, young hardwood.
Silver Berry Eleagnus commutata
This is a very attractive silver bush with silver leaves and even silver
berries which will create interesting contrast in the landscape. It can
be invasive as it spreads by creeping roots. This character makes it especially
useful for filling large areas. Grows to about 2m.
Twining Honeysuckle. Lonicera dioica
This is a very nice climber with bright orange fragrant Flowers in early
summer. Can be grown from cuttings or seeds. Highly recommended.
Willows. Try Pacific Willow Salix lucida,
or Sandbar Willow Salix exigua
For a something interesting in the shrub border or wind break. Pacific
Willow has very nice form with fine lance shaped leaves. The Sandbar Willow
has an extremely upright growth habit and interesting nut brown bark on
the new growth shading to a soft pink/grey on the old wood.
Gardening with native plants can be very enjoyable. It may be possible,
that the right sorts of trees and shrubs will attract the native wildlife
more successfully than imported varieties, so there may be other benefits
to using native plants in your garden. Don't be afraid to try some new
plants, you may be surprised at how wonderfully well they fit into your
landscape plans. Good luck and good growing.
NATIVE AND WILD PLANTS
Many plants that grow wild around Alberta can be harvested for ornamental
uses, for their seeds, and herbal qualities. Some of these are truly native
Alberta plants, some are escaped garden plants, like Baby's Breath, and
Tansy, and some are escaped crop plants like Reed Canary Grass. We really
don't care how they got there, only that they grow in abundance, and that
our collecting them will not harm the ecosystem, or endanger the environment
in any way.
For truly native Flowers, the rule is to pick only l/10 of any stand,
leaving the remainder for seed production and for animals. DO NOT DIG
UP ANY PLANTS. Be very careful how you pick these, which ones you pick,
and what else you damage while you're picking. See the Alberta Native
Plant Council's Guide for Collectors.
In general we don't want anything rare, we only want the types that grow
in large numbers so we can get a large volume of product. The exception
is for seeds. Seed of native Flowers can be very valuable, especially
for relatively rare types. Again, collect only l/l0 of the total stand.
Be careful of other people's property. Do not cross fences. Usually you
can find more than enough to pick on unfenced open areas and along roadsides.
Ask permission to collect on someone's property, usually there is not
a problem.
NATIVE PLANTS, WEEDS AND FLOWERS
Anise Hyssop. Agastache foeniculum
Blue Flower spikes that dry well. Grows in semi shade. Licorice scented
leaves. Not usually enough volume to collect Flowers, but seeds can be
plentiful. Collect some seeds and grow these in your garden to assure
a large harvest in the future. This is a multi purpose plant: fresh leaves
for herb, dried leaves for tea, plant divisions, fresh or dried Flower
heads and seeds. See Seed Collectors Guide.
Aspen Poplar. Populus tremuloides
Very nice green leaves if picked early in the season before the insects
eat holes in the leaves, but late enough so that leaves are stiff, with
enough cellulose to dry well. Bundle in handfuls of about 4 or 5 stems,
2 - 3 feet long, and hang to dry. Very good in leafy, green wreaths, and
swags. This could be a new product for us to introduce to the industry.
Baby's Breath. Gypsophila paniculata
Escaped from gardens. Same variety as cultivated, but tends to have heavier,
coarser stems. Very robust. Pick only the best quality, whitest Flowers.
Go back to the same spot every 2 - 3 days to continue picking as the Flowers
are ready. Put five large stems in a bundle, or more smaller ones. You
can compress fresh bundles by rolling them in newspaper, but you must
open up the bundles and shake them out before hanging to dry. We will
take delivery of fresh product. Worth looking for stands of this in the
country. Hard to ship dry because of large volume. May be easier to ship
fresh and compressed. Quality will deteriorate if the bundles are left
tied up small for too long, fungus can develop and produce brown spots
on the Flowers. Very high volume crop. See Fresh Flowers, Dried Flowers.
Cattails. Typha latifolia
Must be picked while the head is still mostly green. The top half of the
head contains a huge amount of pollen. You should either strip this off
or cut it right away when picking. Strip off some, but not all leaves.
Bundles of l0 - 15 stems. Not a high volume crop.
Grasses. Many types of grasses
Choose types that grow plentifully, so your time is well spent. Sloughs
are good for large clumps of grasses. In general pick when green. Mature,
golden heads will shatter too easily. Pick into handfuls and tie with
a rubber band. Hang to dry. Try Reed Canary Grass, Timothy, Brome. Some
native grasses will be worth collecting seed, but good species identification
is important. See Seed Collectors Guide.
Greens
Fresh green branches of fir, spruce, pine and other evergreens for Christmas
greens. High volume for good quality branches.
Horsemint. Monarda fistulosa
Mint family, square stems and tubular purple Flowers. Common in foothills
and northern Alberta. Relatively easy to collect seed if you mark the
plants so you can find them later in the season. In very large stands
it may be possible to collect Flowering stalks in sufficient volume. You
will get taller and more floriferous plants from cultivated, garden stock,
so it's better to collect seed and grow this in your garden.
Moss. Green Sphagnum Moss
White Lichens and other types of moss are a staple in the ornamental plant
industry. Most of the moss is brought in from BC, at relatively high shipping
costs. Alberta moss is comparable in quality and value, and fairly easy
to find and collect in some parts of Alberta. This needs a steady supply
of quality product that can be sold at a competitive price. Worth researching
to develop the best harvesting, processing and packaging methods. This
should be a standard, year round product, worth developing the system.
Pearl Yarrow. Achillea ptarmica
Also known as Bridal Veil. Perennial. Can be propagated from stem cuttings,
divisions, or seed. Very good white Flowers, used like large Baby's Breath.
Rare. Better to collect seed and cultivate these in your garden for a
larger supply. This is another multi-purpose plant. Fresh or dried Flowers,
root divisions and seeds are all saleable.
Reed Canary Grass. Phalaris arundinaceae
Grows around sloughs in large clumps. Pick when green or green with slight
purple blush. Fully mature seed heads shatter too much, don't pick these.
Grab a large armful, twist slightly and cut off no longer than 30"
long. Shake out bottom leaves and comb roughly with fingers to remove
some more leaves. Tie with a rubber band and hang to dry. Reed Canary
dyes very well so we anticipate a larger volume demand for 1996.
Rose. Wild Alberta Rose. Rosa woodsii
We use these petals, Flowers, buds and rose hips in our Prairie
Rose Potpourri. These are pesky to collect, but for potpourri uses, they
need not be really clean, and could have leaves mixed in. Rose hips on
a 2 foot stem are good at Christmas time, but hard to handle. Clean rose
buds are a high priced product and may be worth collecting.
Sage. Artemesia
Many types, most silver, grey, green and fragrant. Pick as tall as possible.
Clary sage can be identified by its unpleasant odor and yellow Flowers.
Don't pick this one. Most other types are good. Pick before Flower buds
open about the end of June. Leafy stems with no Flower buds are also good.
Once the Flowers have opened and dried, the stems are less attractive.
Try Wormwood Sage and Pasture sage.
Seeds
Seeds of native plants can be very valuable. Look for unusual species,
Flowers of any kind, fancy grasses. Collect seed all through the summer
from June to September. Store in a cool, dry place. Be sure to label well.
If you're not sure of the identity of the plant, save a stem with seed
pod, leaf, etc. to help identify later. Make a note of where you collected
the seed, and the date. Use Budd's Flora of Alberta, or any other good
resource. We can identify many types here. We will accept seeds either
cleaned or not cleaned, but cleaned seeds are worth more. There are some
efficiencies in methods for cleaning seeds. Don't waste time doing this
the wrong way. Use a collection of sieves, flat pans, and blowers for
best results. Collect only l/10 of any stand. Avens, Lupines, Clematis,
SunFlowers, Gaillardia, Brown Eyed Susan, Anise Hyssop, Campanula, Veronica,
ConeFlower, Blue Flax, and so on. See Seed Collectors Guide and Seed Savers
Guide.
Tansy. Tanacetum vulgare
Tansy is an escaped garden plant, brought to Canada from Europe by the
early settlers in the days before hybrid petunias and snapdragons were
available. It is on the noxious weed list because of its pernicious growth
habit. It can cause abortions in cattle so farmers don't want it on their
pastures. DO NOT CULTIVATE THIS PLANT. It is very common on roadsides
all over central and northern Alberta so there's no need to grow your
own. Pick bright yellow Flowers only, with no brown showing yet. If picked
too early, the Flowers will shrink and dimple when drying. Picked too
late, the Flowers will show brown edges when dry. Align Flower heads into
umbrella shape, approx. 12 - 14" across at the top, 20 - 25 stems.
This is a very high volume product. Tansy is now imported from Holland
for the craft trade. Recommended, but it's easy to get too many bundles
because of the ease of picking, so go easy until we have the international
marketing down pat.
Twigs
Bare, woody branches without leaves on them are available from
leaf fall around October to leaf bud in April. Almost any type is useful.
Try Birch, Alder, Willow, Dogwood. Stay away from Balsam Poplar because
of the sticky stems. Fresh twigs can be made into wreaths, swags, baskets,
corners, and just bundles. Collect 2 - 3 foot tall twigs with good shape
and color. Taller stems can have fewer branches in a bundle. Branches
should have clean, new growth bark, not damaged or rough looking. The
twigs can be either straight, unbranched stems, 25 to a bundle, or branched
stems with good shape, 15 to a bundle. Make into tidy bundles of all one
type, size and color, and fasten securely with a rubber band. See Pussy
Willow Picker's Guide.
Yarrow. Achillea millefolium
White Flowers. Very common. Cultivated plants will have bigger Flower
heads. 25 - 35 stems. Align Flower heads at top into an umbrella shape.
Hang to dry. Not a big seller, and pesky to pick from the wild. This is
better cultivated so you get larger Flowers and it's easier to make a
bundle up. Seed is more valuable than the Flowers.
Yarrow. Achillea sibirica
White Flowers. Similar to common yarrow and same handling. Save Seed rather
than Flowers.
Willows
Good for pussy willows, bare twigs for weaving, colored twigs, willow
furniture, etc. See Pussy Willow Picker's Guide.
