So rare, so charming and SO eager to bloom! I’m smitten with this sunflower native to California and Southern Oregon. With a shorter, chubby, 3’ tall x 30” around dense habit, it’s easy to place in the garden – like, right up front! Loaded with 2” flowers sporting an extra-large central disc, the flowers are displayed all the way to the base of the plant – cool! Blooms for months from Spring to late Summer. Tolerates poor to average soil, even serpentine, and goes nuts in compost-enhanced soil, as shown here. Self-sows! A true magnet for bees, butterflies and other pollinators, plus adorable cut flowers! Deer resistant!
