CALLIRHOE involucrataAll Season662
Wine Cups, Prairie Rose15cm  Zone: 3
Native to the short-grass prairie and sandy, dry soils of western and mid-western North America and an outstanding plant for the garden.

The flowers are glowing, satiny magenta cups, up to 2" across which begin in June and never cease until frost. Its leafy flowering stems are prostrate and will spread out 1-3' from the crown by midsummer, so give it plenty of space in a sun-baked spot.

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.

COREMA conradii New Early Spring1034
Broom Crowberry30cm  Zone: 4
In mid-April, the sand barrens of the Annapolis Valley in Nova Scotia are a haze of bronzy red/purple as the small flowers of Corema bloom en masse. Closely related to Empetrum, this is a beautiful small, mounded evergreen resembling a heath with needle-like foliage whorled on thin stems. Part of the Coastal Plains Flora; it is rare across it's range; although it is often hard to imagine this when one is in the midst of a large colony that can extend over acres. This is an elegant plant, grown for it's beautiful foliage all season. For full sun, in an acid soil. Seed wild collected in Nova Scotia.
Germination Instructions: Research on germination discloses massive germination in the wild the year following fire; yet mimicking these same conditions artificially has not produced the same result. Otherwise the only method that has produced (sparse) germination is cold treatmen

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.
