Eschscholzia californica This mix is the fanciest of the California poppies. The flowers are semi-double with fluted petals and a silky, chiffon-like texture. The finely divided, gray-green foliage sets off a summer-long display of shimmering, 3-inch, jewel-tone blooms. The vivid colors range from sunny yellows and tangerines to magenta. Height: 10–14 inches. Sow in the fall and yours will be the first to bloom in spring. Will self sow. An outstanding border plant. Approximately 600 seeds per gram. Germination code: (4)
