Erythronium albidum (White Trout Lily/Dog's Tooth Violet)
This is truly one of the most endearing little wildflowers that I know. It may be diminutive, but it's packed with big beauty and then some. Erythronium albidum has short stems, each with two tulip like mottled leaves. The lily-like flowers aren't really white, but more pale lavender, with bright yellow stamens. What makes it so endearing is the way the blooms tend to nod downward, opening in daylight and closing at night. Erythronium albidum will form colonies if it is happy, and it will be if grown in part shade to full shade and in moist, loamy soils. Erythronium alblidum has been used medicinally and its stamens used as a saffron substitute by early settlers. Quart pots. Limited.

Erythronium americanum (Yellow Troutlily/Dog's Tooth Violet)
Another native spring ephemeral for the woodland garden. Called yellow trout lily because of the mottled leaves and because it blooms in trout season, this showy, nodding yellow beauty will form colonies if left undisturbed. It prefers full to part shade and moist, humusy soil. After blooming, it will become dormant, so remember where you plant it. Zones 3-8.
