Toyon (Heteromeles arbutifolia) Perennial. Plant in full sun or partial shade, give moderate water. Grows to 6-10 feet tall and as wide. USDA zones 7a-11. Note: this is the shrub that gave Hollywood it's name. Folks who first saw the area covered in these shrubs assumed it was holly. Photo by Holly Guenther.
landscape designer Karen Donnelly combined coral, fiery orange, red, and yellow flowers with lime green and deep green tropical foliage. A pot filled with elephant's ear and potato vine adds height and structure to the planting. In cold-winter areas, build the border for just a season, then start over next year. Or move the most valuable plants indoors for winter. You can also substitute hardy look-alikes, such as Japanese banana and honey bush, for true tropicals.
It loves partial shade and flourishes in a zone 6-7 or warmer. So take my advice and add a little Hardenbergia to your life! Plus when they really need water they get a bit droopy, but are very forgiving
