Chocolate Daisy
Berlandiera lyrata, also known as Lyreleaf Greeneyes or Chocolate Daisy, is a night flowering perennial with small, two-inch flowers that is endemic to the United States' grasslands, masas, and rocky, limestone soil.
The Chocolate Daisy, so named because of its chocolate-like aroma that is most evident in the morning, blooms at twilight. The blooms feature eight ray-shaped yellow petals that circle a center disk, and the stems range in height from one to two feet.
However, while Chocolate Daisies smell like coca, are classed as a herb, and are edible, they do not taste like coca.
Chocolate Daisies, which repel deer but attract butterflies, would be a fantastic addition to a backyard garden in USDA planting zones 4-10. If you like daisies, this is the plant for you.
