Native to the American West, the Poached-Egg Plant is just 6-12" tall and 6" wide, yet is sweetly fragrant, a magnet for butterflies and bees, and terrifically floriferous over a long summer-to-fall season.
Find a sunny spot for this annual, which delights with ferny divided foliage and bright yellow-and-white blooms - held in a shallow cup shape - on slender stems. It is delightful in containers of all kinds, large planting at the front of the border or bed, where it can share its fragrance with less-fortunate plants! It makes a nice foreground planting to everything from dwarf Zinnia to long-blooming perennial.
Direct sow seeds in fall or early spring, and plants self sow where adapted.
