Grow Quickly: Hardy perennials are very valuable in the garden and play a major role, as most of them are relatively cheap, grow quickly, and can readily be increased in several ways, including by seed, division, or cuttings. Most of them, like trees and shrubs, live for many years. In addition, most of them, unlike trees and < shrubs, are herbaceous as they have soft stems which die down in the fall and grow again the following spring. A number of them have evergreen leaves, and one or two grow in the winter and die down in the summer. Not all herbaceous perennials are in fact hardy, but here we are concerned only with those that are.
Herbaceous perennials may be used in a variety of ways in the backyard.
Plugs are pieces of sod, one and a half or two inches or so in diameter, of creeping grasses. When planted, they quickly grow together and cover the ground. They differ from sprigs in that each consists of many rather than few of shoots and includes the soil in which the roots grow (sprigs carry little or no soil with them). Zoysia grasses are the ones chiefly propagated by plugs. They make good turf sooner when grown in this way rather than from sprigs.See Also Octidentalis Grow Well:Thuja plicata and T. octidentalis grow well in heavy soils and may be treated as for Lawson cypress. Yew (Taxus)is available in dark green and gold-leaved varieties which may be planted separately or in a mixture. It's slow-growing and so does not need frequent clipping, is very durable and will grow in most conditions including both chalky and limy soils.
Once a framework has been formed, the most important objective is to keep the climber in check—lateral shoots may grow up to 12ft in a single year and unless this over-exuberant growth is pruned, the plant can soon become a jungle of stems and may grow too large for its allotted area. Severely pruning a wisteria during winter will only encourage even more rapid growth.

A greenhouse is the perfect all-weather place to cultivate plants. Not only does it extend the range of plants you can grow, but it provides the right atmosphere to propagate and overwinter less hardy plants, or grow tender ones. As well as the extra heat, factors such as the quality of light and length of day all play a part in helping plant growth.
