ROMNEYA or CALIFORNIAN TREE POPPY

P. Plant in late March against a sunny, sheltered wall. Light, gravelly soil is preferred — this plant dislikes heavy land, but rich ground is quite unnecessary. The large white flowers of Romneya coulteri have a mass of yellow stamens, appear in late summer and have some fragrance. The blue-grey foliage is pleasing. Usually dies back to soil level in winter and should be protected with bracken etc. R. trichocalyx is very similar, possibly a little hardier. Increase by root cuttings about 3 in. long in March and lay horizontally in boxes of sandy compost placed in a closed frame with bottom heat.
