|what are the best perennial, year-round bloomers for Hardiness Zone 10?|
|The most floriferous of all Blanket Flowers, this hybrid sets its big yellow-and-orange blooms for many months, so your garden is never "out of bloom". 15 inches high and wide -- a good size for flowerpots as well as the garden bed and border -- if you keep the flowers picked or deadheaded, new buds will appear. Dwarf Blazing Star offers bright rosy-purple plumes on neat 12-inch stalks. Plants bloom abundantly, in full sun or part shade, remaining attractive long after bloom with fresh, grasslike foliage that stays neat and colorful well into fall. Blooming height: 2 feet tall, about 18 inches wide. Porterweed (Stachytarpheta) is one of the best butterfly attractors. It blooms year round and sprouts back quickly from
frost and freeze. Plants grow about 4? tall by 6? wide before stems droop and touch the ground. Pruning is the best way to keep the plant in check. It re-blooms quickly after pruning during warm months. Flowers are borne terminally on long, stringy
spikes at the ends of the stems. Devil?s backbone is a succulent that adds bright contrast to green or colorful landscapes and requires very little care after establishment. It is tender to frost and freeze, but usually re-sprouts from the roots. Hope this short list is helpful.
