The crushed leaves of this aromatic perennial smell like a mixture of mint and licorice. Attracts hummingbirds and butterfies. Good cut flower. One of the easiest plants to grow. Clumping, but will self-seed.

Bloom time: July, August
Height: 60-90 cm (24-36")
Full sun to part shade; well-drained sandy or loamy soil

Seeds have good germination. Plant directly into the garden in mid-June. Seedlings are fast growing and can be moved to their permanent location by late summer.
Agoseris glauca
False Dandelion
Aster family – Asteraceae/Compositae

Found along roadside ditches, grassy areas – prairies and meadows. Flowers generally 2-5cm (1-2”) in diameter. Gorgeous pure white cotton ball seed heads.

Bloom time: July-August
Hight: 60 - 90cm (2 - 3ft)
Growing conditions: Full sun; average to moist soil.

Sow seeds directly into the garden in late fall. If starting indoors, moist cold stratify for 4-5 weeks.
Allium cernuum
Nodding Onion
Lily family – Liliaceae

One of the showiest perennial onions with pink to pinkish-white flowers. A short plant that can also be used in rock gardens and herb beds. Easy to naturalize in garden or grassland. Habitats in the wild are open woods, meadows and prairies.

Bloom time: May - July
Hight: 15 - 50 cm (6 - 20”)
Growing conditions: Sun to semi-shade; average garden soil.

Difficult to germinate. Plant direct in late fall. If starting indoors, moist cold stratify for 4-5 weeks. Germinates best in dark but needs to be close to the surface of the soil.
Antennaria neglecta
Broad-leaved Pussytoes (Field Pussytoes)
Aster family – Asteraceae/Compositae

Looks very similar to A. parvifolia but the leaves are slightly bigger.
The leaves come in various shades of green, but are always silvery or white on the underside.
This species is not as drought tolerant, and is found in damp meadows.

Bloom time: May, June.
Height: 10 - 25 cm (4 - 10 ")
Sun or semi-shade and average soil. Likes a clear open location.
Antennaria parviflora 
Little-leaved Pussytoes (Small-leaved Pussytoes, Small-leafed Everlasting; Little-leaf Pussytoes)
Aster family – Asteraceae/Compositae

Survives in a hot, dry location and will also grow in the very dry, semi-shaded areas close to evergreen trees. An excellent ground cover - spreads into a nice soft mat, covering bare ground even in stony areas. Also good for planting between flagstones in a path or in a rock garden. This plant spreads by short, above-ground runners called stolons, but is not aggressive.

Bloom time: June through August
Ht: 10 – 25 cm (4-10”)
Sun; well-drained poor soil.

Sow seeds directly into the garden in late fall. If starting indoors, moist cold stratify for 2-3 weeks.
Antennaria rosea  
Rosy Pussytoes (Pink Pussytoes) 
Aster family – Asteraceae/Compositae

Mat-forming perennial. No longer found in the Edmonton area, although often found on dry, rocky alpine ridges. The common name of Pussy-toes comes from the tiny, soft, fuzzy flower clusters, which resemble a kitten's paw. The alternative name of Everlasting for the above refers to the papery fruiting heads, which persist for much of the summer.

Bloom time: Early summer
Ht: to 20 cm (8”) with flowers
Full sun; average soil.

Grow from seed as above.
Aquilegia brevistyla
Blue Columbine
Crowfoot family – Ranunculaceae

Woodland plant with showy purple and white flowers on long flower stems.

Bloom time: Early to mid-summer
Ht: to 50 cm (20”) with flowers
Full sun to dappled shade. Grows at the edge of woods in the wild. Moist well-drained soil.

Sow in the garden in fall. If starting indoors, moist cold stratify for 2-4 weeks.
Aralia nudicaulis
Wild Sarsaparilla
Ginseng family - Araliaceae

A groundcover of Aspen and mixed wood forests.
Each stem has one compound leaf that is divided into 3, and each division, in turn, has 3 - 5 leaflets so that each plant looks like it has 3 leaves.
These leaves can form a thick umbrella-like canopy over the forest floor, so that the greenish-white flowers and purple berries are quite hidden.

Bloom: June, July.
Height: 30 - 40 cm ( 12 - 16")
Grow in semi-shade to deep shade.

This species can spread agressively once established.
Arnica chamissonis 
Meadow Arnica (Chamisson's Arnica, Leafy Arnica)
Aster family – Asteraceae/Compositae

Spreads by underground rhizomes - however, it has shallow roots and it is very easy to dig out unwanted plants. To keep from spreading, surround with a length of 15 cm (6") wide lawn edging buried in the soil flush with ground level.

All Arnicas are poisonous.

Bloom time: June, July
Ht: 45-75 cm (18 – 30”)
Full sun. Very hardy; grows in any soil; prefers a sunny spot with a moderate amount of water.

Sow the seeds in late fall or late spring directly into the garden.
Artemesia frigida 
Pasture Sage (Pasture Sagewort, Prairie Sagebrush)
Aster family – Asteraceae/Compositae

A great drought-tolerant plant for bare eroded slopes.
This species will not spread agressively like Prairie Sagewort.
The finely-divided lacy leaves are silvery-green and sage scented.
Flowers are greenish-white, small and inconspicuous.

Bloom time: July, August.
Height: 20 - 50 cm (8 - 20")
Full Sun, well-drained poor soil.

Artemisia ludoviciana
Silver Wormwood (Prairie Sagewort) 
Aster family – Asteraceae/Compositae

This species spreads rapidly by underground runners and can quickly
form a large dense patch on bare ground. It is very tough and drought-tolerant.
Foliage is grey-green and the flowers are tiny and inconspicuous.
Stems and leaves are used by Aboriginal people for smudging.

Bloom time: July, August
Height: 20 - 60 cm (8 - 24")
Full Sun; poor soil.
Asclepias ovalifolia
Low Milkweed (Oval-leaved Milkweed)
Milkweed family – Asclepiadaceae

Small fragrant flowers attractive to a wide range of butterflies. (Monarchs have been observed on Low Milkweed in Edmonton).
Slow rhizomatous spreader. Large seed heads burst open when ripe to release clouds of white silk.

Bloom time: June, July
Ht: 20–60 cm (8-24”)
Sun to part-shade; any soil; can take dry conditions.

Sow the seeds directly into the garden in late fall. If starting indoors, moist cold stratify for 2-4 weeks.
