Romneya coulteri - Matilija Poppy

Description

One of our most beautiful California native plants. Large white flowers have a bright yellow center, and appear from May to July, or longer if given some water. It spreads from underground rhizomes that can be invasive. Not the easiest plant to establish, but worth the effort. Winter planting is best and be careful not to disturb its roots when planting. Old stalks should be pruned back to ground level in late winter.
