Rainy Side Notes
The name erythronium comes from the Greek word erythros meaning red, named for the species E. dens-canis color from which dye was made.
Erythronium oreganum, from the lily family, is a spectacular site in the garden, especially when planted in drifts in a woodland setting. When you receive your new bulbs, plant them right away; as with most bulbs in the lily family, they do not go completely dormant. Plant bulbs 4-6 inches deep.
