Romneya coulteri...no relation to either Ann or Mitt, is a rare California endemic, highly prized by gardeners who are lucky enough to be able to grow it. Dry soil and full sun are the keys to success. I admit to killing fifteen, now that the statute of limitations for involuntary plant slaughter has passed, before achieving success. When happy, romneya spreads well via underground rhizomes. The 4-6' tall silver stalks are adorned by silver foliage and topped in late spring with large crepe paper-like white flowers, highlighted by yellow central stamens. Do not disturb the roots when planting matilija poppy. Like cultivation, propagation of Romneya coulteri is very difficult, so our supply of these seed-grown plants is limited.
