Lantana Heads are Clusters of Tiny Flowers in Shades of Red, Pink, Yellow and Orange, Sometimes all in One Cluster

Lantanas are perennials grown as half hardy annuals in most climates, or wintered over indoors. Lantana camera can grow as tall as 10 feet in very warm climates but is usually no more than three feet tall, and dwarf varieties no tall than 18 inches are very popular. Little round flower heads are clusters of tiny flowers in shades of red, pink, yellow and orange, sometimes all in one cluster. Alba is a white variety. Trailing lantana l. sellowiana is less hardy, with trailing stems and flowers that are usually combinations of lavender and yellow. 

Both are excellent container plants but are also grown in gardens, the trailing kind as a ground cover. Lantanas are warm weather plants. Sow seeds indoors in late winter because they take a long time to germinate. In warm climates sow outdoors in the garden, as several gardeners buy plants and then stem cuttings when they need new ones to bring indoors for winter display and for a source of new cuttings for the following season. Plants can also be dug up, cut back to five to six inches, and kept dormant in a frost free basement until early spring with just enough water to keep them alive but not enough to produce new growth.

Snakeroot or Bugbane

This woodland plant, native to the eastern United States, is not well known but really a delight to grow. Its flowers tall fuzzy white spikes. The leaves are attractive and fernlike rather like that of astilbe. Cimicifuga racemosa grows five to six feet tall, sometimes even taller and flowers in mid to late summer and flowers in mid to late summer sometimes earlier. C. simplex grows about three feet tall and blooms in fall. Moreover both species like part shade and moist, woodsy soil, but C. Simplex will do well in full sun. Division is not necessary but the stems often need to be stake up to where the flower begins.

Shasta Daisy

Shasta daisy or Chrysanthemum x superbum (C. Maximum) are always white, but can be tier single or double, tall short. They generally bloom for a long time in summer, especially if the flower stems are cut, and are a good white accent. “Alaska” and “Polaris” are among the hardiest tall varieties both the single and “Marconi is a double variety. Little Miss Muffet is a single that grows about a foot tall. Well, though to provide rich moist, well-drained soil. IN hot climates provide light shade. Pinching the stems in early summer will make the tall varieties bushier. Clumps are sometimes short-lived; established ones respond well to division.

A.tomentosa is a very pleasing low variety that forms a mat of whitish leaves and has flowers less than a foot tall. It is nice in the rock garden or at the front of the border. Yarrows are sun loving and drought resistant. Some are rather spread and need to be divided frequently. All in fact benefit by division every few years in fall or early spring.
