Calendula : White Chiffon™ Hibiscus Rose of Sharon Shrub
This tough customer puts up with heat and humidity to bloom from June through October!
Large bush...althea
Large, double blooms of pure white with a lacy center dot this charming little shrub from June through October! One of the longest-blooming as well as most prolific Hibiscus, White Chiffon is a carefree joy you'll want for the hot, sunny summer garden.
From June through October, this rugged shrub is simply a blizzard of fully double 3-to 4-inch blooms, each with a frilly center that adds texture and impact to the flower. They arise on handsome shrubs 8 to 12 feet tall and 4 to 6 feet wide. Few shrubs are more heat- and humidity-tolerant than Hibiscus, which basks in temperatures that make others wilt and brown out! Give this shrub plenty of water and nonstop sunlight and you've got a bloom machine 5 months out of every year!
White Chiffon is a nice choice for a foundation planting, accent in the patio or other garden nook, or hedge. It makes a fine companion to Lavender Chiffon, and a nice background planting to Dwarf Russian Sage and other low-growing shrubs, as well as colorful annuals and perennials of all description. No shrub is easier -- this is one tough plant, untroubled by pests and disease and able to maintain itself through good weather and poor alike. No wonder it was awarded the prestigious Green Thumb Award by the Mail Order Gardening Association!
Space these shrubs about 4 to 5 feet apart for a dense "wall" of showy color. Zones 5-8
