This patch of trout lilies, Erythronium americanum, is growing by the roadside on the edge of a drainage in the woods near my house. Trout lilies are so called because the mottled leaves are thought to resemble the markings on brook trout, but it has other common names: adder’s tongue because of the look of the new unfurling leaves, and dogtooth violet because of the appearance of the white corm, but, of course, it is not a violet at all.
Trout lilies can join other spring ephemerals like bloodroot in the garden. They like fertile moist soil and enough sun in the spring to warm the soil in the spring, but shade throughout the rest of the year when they will have dried up and disappeared. They spread most reliably by creating new corms: while they may form a good sized colony they are not at all invasive. If you buy potted plants in the spring for your garden make sure they are nursery-propagated because native wildflowers are under siege everywhere.
I have so little shade in my garden that I really love finding wildflowers in my local ‘wilderness.’
