Use All Your Spaces By Planting In The Shade

Shade is measured by the amount of light cover an area receives. Depth of shade can be measured from total to partial and various degrees of light and dappled. Areas may have shade for only a short period of the day, but dense shade is by far the most difficult type of shade in which to garden. The problem is that plants need light to photosynthesise and produce food; so only those plants with low metabolism are able to survive.

You have no doubt noticed that most of the woodland perennials flower in the spring. This is an evolutionary adaptation that was derived by the lack of leaves on deciduous trees in springtime. Plants that grew underneath the large deciduous trees found that they had to grow and flower while the leaves were absent and light was abundant. Once the trees leaf out and the amount of light diminishes, the flowers are through with their moment of glory and once again retire until the following year.

Light or partial shade is an ideal condition to grow a wide variety of garden plants. Light shade occurs where there are smattering of large and small trees, where indirect rays of light can filter through the canopy of branches. Increased light can be accomplished by selective removal of trees and shrubs, or through removal of many of the lower tree limbs.

Generally, plants that prefer cooler conditions benefit from sun in the morning and afternoon shade during the heat of the day, while plants that love heat benefit from shade in the morning and prefer to bask in the hot afternoon sun. Plants do not fall into neat groups, but by careful selection even the most shaded garden can enjoy colour and interest at some point of the day or season.
