Melampodium–commonly called butter daisy–has white-rayed, cream, or yellow daisy-like ray flowers with dark orange centers. Melampodium is a bushy plant with narrow bright green to gray-green leaves. The plant can become floppy as it matures.
Melampodium is an excellent choice as a summer bedding plant where deer are a problem; it is deer resistant. The flowers attract butterflies, bees, and other pollinating insects. The seeds provide a food source for small songbirds, such as goldfinches.
Use Melampodium in borders, masses, cutting gardens, and containers. It contrasts well when planted in the landscape with many other summer annuals. Smaller varieties are compact and are excellent additions to annual container combinations.
