(Eschscholzia californica) This Thai Silk 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, 7cm, jewel-tone blooms. The vivid colours range from sunny yellows and tangerines to magenta. One of our absolute favourite field flowers. Order your California poppy seeds Today with Fontana Seeds.
