Marcus, Joseph A.

Cooperia pedunculata

Hill Country rain lily, Prairie lily, Rain lily

Liliaceae (Lily Family)

USDA Symbol: cope

USDA Native Status:

Rain lilies pop up and bloom two or three days after good rains in the spring and early summer. They begin to open slowly about dusk and are fully opened the next morning. Flowers are trumpet-shaped for a few hours after opening, but the 3 petals and 3 sepals, all white, spread widely to 2 inches across as they mature; they last only a day or two. The fragrant blossom is at the top of the single, unbranched stem, which is 5–9 inches high. The leaves are at the bottom, 6– 12 inches long and 1/4 inch wide.

Conditions Comments: These bulbs produce blue-green grass like leaves with slightly fragrant, shimmering flowers, mainly in spring, that have a color that evolves over two days from white to silky light pink. Rain lilies make for nice surprises after a rain and combine well with plants that have short foliage, such as cardinal feather and silver ponyfoot. In flower beds, meadows, and pots, these rain lilies grow easily from bulbs. The flowers will last a little longer in shade. Plant 8 inches deep for more flowers. Plant 4 inch/shallow to increase the bulbs. This species typically blooms in the Spring, while C. drummondii blooms in the Fall.
