Trees and plants are called ornamentals if their main job is to add beauty and interest to a garden. Dogwood trees, for example, are a popular ornamental in some areas because of their white or pink blooms in the spring. Cherry and plum trees can also add beauty to landscaping even if they never produce fruit.

Ornamental trees and bushes or shrubs can serve other useful purposes besides just looking good. Some also smell good and can be used to make scented oils -- for example, lavender and lilac.

Ornamentals can be used to mark the border of a property or to provide privacy from neighbors. They can be used to hide trash cans and storage sheds.

Most ornamentals have the same needs as other plants -- water, mulch, pruning for shape and inspection for pests. But master gardener Bob Orazi says, "Most of them take care of themselves after the first six months."

Bob Orazi is a horticultural adviser in Howard County, Maryland. Years of experience have shown him that people often decide to plant an ornamental bush when they see one in bloom. They might see the yellow blooms on a forsythia bush -- one of the first signs of spring -- and decide to plant one. But he says most ornamentals are better to plant just before their leaves open.

Some ornamentals and other plants are sold with their roots in a ball of dirt held together with burlap. But David Robson of the University of Illinois Extension says more and more plants are grown in containers. They are easier to ship that way.

However, the roots may become encircled by growing around and around in the pot. So his advice is to pull the plant out of the container, then cut the bottom half of the root ball into four parts.

This process is known as "butterflying." The bottom of the root ball will look something like the spread-open wings of a butterfly. David Robson says planting the root ball this way will improve growth.

DAVID ROBSON: "It is amazing on a tree or shrub how much faster growth you will get. But you do have to remember by butterflying, you are cutting down the overall height of that root ball. So maybe butterfly it first and then measure how tall your root ball is. Then dig your hole. Make sure you do not dig it too deep so the plant is sitting below the soil line."

He also advises against letting shrubs grow taller than four and a half meters.

DAVID ROBSON: "[If] some shrubs get too tall, you start losing their ability to produce good flowers."

In that case, your ornamental plant might not be so ornamental.
