Selection of a suitable plant for groundcover depends on the area where it will be grown. Some groundcover plants prefer shade. Others thrive in full sun. Some prefer moist soil, while others need dry or well-drained soil. To work well as groundcovers, plants have to be tough, durable, and relatively fast-growing but not invasive.
All groundcovers are perennial and most are evergreen .
Because groundcovers live for many years in the same spot, it is worth the effort to prepare the soil well before you plant them. This allows plants to establish good root systems. Perennial weed areas should be cleared before planting groundcovers, since most cannot compete against established weeds. Improper soil preparation is a frequent cause of groundcover failures. The soil should be worked to a depth of 8 to 10 inches.
