CALLIRHOE involucrataAll Season662
Wine Cups, Prairie Rose15cm  Zone: 3

It differs from the species by having a longer flower raceme, but with flowers less dense.

COLCHICUM autumnale New Autumn1005
Autumn Crocus10-15cm  Zone: 4
This European species is the best known and earliest- blooming of the fall-flowering bulbs. It is particularly dear to me as a vivid childhood memory of meadows in southern Germany in solid bloom. Commonly referred to as the autumn crocus colchicums are not related to crocus at all, but are actually members of the lily family. Beginning in mid-September they produce large, goblet-like blooms in shades of pink, violet or white. Colchicum bloom without leaves leading to common names such as "naked ladies" and are quite beautiful in their simplicity. The leaves do not appear until spring, arising then without flowers, but (hopefully) with large seed pods, a fascinating delayed mechanism of seed production.
Germination Instructions: Cold treatment required.

A one-species genus native to eastern North America.

COMPTONIA peregrinaSpring1015
Sweet Fern60-90cm  Zone: 3
Native to northeastern North America growing in openings in coniferous forest in well-drained, dry, acid, sandy or gravelly soils. The thin, narrow dark-green leaves are deeply divided into many lobes, resembling a fern. The whole plant has a beautifully spicy, aromatic odor, which is more pronounced when the leaves are bruised. It is densely branched, and rhizomatous in habit. Bark is smooth, shiny reddish-brown and heavily lenticeled. Both male and female flowers are produced. The former are borne in large cylindrical catkins in clusters at the ends of the branches and the latter in small egg-shaped catkins. Because it fixes nitrogen, does well on disturbed sites or sites with sterile soil. Drought and salt tolerant. An intriguing plant that performs wonderfully on poor, dry, sandy, acid soils. Seed wild collected in Ontario.
Germination Instructions: Seed requires cold treatment. Outdoors over winter recommended, as oscillating temperatures stimulate germination.

CORNUS stoloniferaSpring1054
Red Osier Dogwood1-3m  Zone: 3
For winter interest, this is surely our best native Cornus, displaying striking crimson twigs that color the landscape even in the bleakest winter. Understandably, it is the parent of a slew of hybrids. Found in moist areas, with a native range extending over much of North America, it is a spreading, many branched shrub, covered in spring by large clusters of creamy-white flowers, which attract butterflies. These produce whitish berries, with a blue tinge in mid to late summer. Many birds are attracted to this species as the berries provide food and the dense, twiggy nature of the plant is perfect for nesting and hiding. The leaves turn from reds to purples in the fall and the shiny, smooth red twigs, which give the plant its name, turn brilliant in cold weather and look striking against a snowy winter background. The young branches, (osiers) of this shrub have been used by Native American Indians in making baskets and the bark of the stems has been traditionally collected to make a red dye. Seed wild collected in Ontario.
Germination Instructions: Cold treatment required.

300 species with finely dissected, often blue-green foliage and yellow, blue, pink or rose-purple tubular, spurred flowers in the spring. "Corydalis" is Greek for "lark" referring to the lark-like spurs of the flowers. Many species cannot tolerate dry storage and must be sown fresh. Source: Liden & Zetterlund, Corydalis, Timber Press.

Biennial. Self-sows to perpetuate. Not recommended for warmer regions of the world, as it may become too vigorous in the garden---but just enough in cold-weather gardens.
Germination Instructions: Seed has been moist packed to preserve viability. Cold treatment required.
