C. xgrandiflorum (C. x morifolium). FLORISTS' CHRYSANTHEMUM. Perennial. Zones US, MS, LS, CS; USDA 6-9. The most useful of all autumn-blooming perennials for borders, containers, and cuttingand the most versatile and varied of all chrysanthemum species. Hundreds of selections are available in many flower forms, colors, plant and flower sizes, and growth habits. Colors include white, yellow, red, pink, orange, bronze, purple, and lavender, as well as multicolors. Not browsed by deer.

It's easy to grow florists' chrysanthemums, not so easy to grow prize-winning ones. The latter need more water, feeding, pinching, pruning, grooming, and pest control than most perennials (see care box above). But if you're not planning on competing in the local flower show, choose from the following old-fashioned florists' chrysanthemumsall longtime border favorites that have survived at old homesites without a gardener in sight. Most have an open, casual look and bloom later than their modern counterparts. Try the following: 'Cathy's Rust', 23 ft., rich rusty red; 'Clara Curtis' ('Country Girl'), 23 ft., rosy pink; 'Ryan's Pink', 1122 ft., soft pink; 'Emperor of China', to 4 ft., silvery rose-pink flowers and red-flushed foliage; 'Hillside Sheffield' ('Sheffield Pink'), 212 3 ft., clear pink; 'Mrs. Hathaway', 212 ft., yellow; 'Single Apricot Korean', 23 ft., pale apricot; 'Venus', 23 ft., pale pink to white; and 'Virginia's Sunshine', 2 ft., soft yellow flowers as late as November.

Flower forms. Following are flower forms as designated by chrysanthemum hobbyists.

Anemone. One or more rows of rays with large raised center disk or cushion. Center disk may be same color as rays or different.

Brush. Narrow, rolled rays give brush or soft cactus dahlia effect.

Reflex. Big double flowers with rays that curl in, out, and sideways, creating a shaggy effect.

Spider. Long, curling, tubular rays ending in fishhook curved tips.
