Nursery contributed plant descriptions

Shrubby or tree-like to 15' tall but usually much less. The 3" yellow flowers are set against rich blue-green leaves 3-5" long. Channel Islands of California.
Catalina Bush Poppy. The library in town had the biggest plant in the state of Dendromecon rigida until the City chopped it out. This is a slightly more tender version but very doable here given full sun against a wall and dry good drainage in lean soil. Yellow flowers. Hortilacious & edgy.
The “Island Bush Poppy” is a very attractive shrub/tree for dry gardens. The flowers are 2” wide, brilliant yellow & contrast beautifully with the blue-green foliage. While mostly Spring blooming, it may also bloom year around & it looks fabulous with the blues of Ceanothus & the reds of Galvezia. The shrub generally grows in an open hemispheric form to 5'-10' wide & tall. In the wild it grows only in chapparal on Santa Rosa & Santa Cruz Islands. In the garden it requires good drainage to thrive, though some people say that it is more a question of transplanting carefully to the garden. So take care to disturb the roots as little as possible!
