The plants normally selected by most landscapers and designers are by nature low-growing, rampant, spreading, creep-crawly things and yet the concept of ground cover demands no such thing. The ideal description of a groundcover plant includes:-

• a bold dense mass of leaves completely covering the ground most of the year; evergreens gain gold stars.
• They should require little or no maintenance - if you have to give the plant more than its share of attention, you might as well save your money and spend the time weeding.
• use the plant on ground areas that are difficult to maintain, such as steep banks or boggy patches.
• use the plant to cover areas where not much will grow, such as deep shade or sandy soils.

Ground Cover a thousand beautiful plants for difficult places by John Cushnie (ISBN 1 85626 326 6) provides details of plants that fulfill the above requirements.

Using these groundcover plants in your planting scheme (either between your trees/shrubs in the border or for the whole border) will - with mulching your beds to a 4 inch depth and an irrigation system - provide you with a planted garden with far less time required for border maintainance.

The groundcover list is sorted in the following pages under the following height of plant range:-

• Below 2 feet (24 inches = 60 cms) in height in Groundcover List 1
  Between 2 and 6 feet (24 - 72 inches = 60-180 cms) in height in Groundcover List 2
  Above 6 feet (72 inches = 180 cms) in height in Groundcover List 3

Surface soil moisture is the water that is in the upper 10 cm (4 inches) of soil, whereas root zone soil moisture is the water that is available to plants, which is generally considered to be in the upper 200 cm (80 inches) of soil:-

• Wet Soil has Saturated water content of 20-50% water/soil and is Fully saturated soil
• Moist Soil has Field capacity of 10-35% water/soil and is Soil moisture 2–3 days after a rain or irrigation
• Dry Soil has Permanent wilting point of 1-25% water/soil and is Minimum soil moisture at which a plant wilts
• Residual water content of 0.1-10% water/soil and is Remaining water at high tension
• Available Water Capacity for plants is the difference between water content at field capacity and permanent wilting point

Sun Aspect:-

• Full Sun: At least 6 full hours of direct sunlight. Many sun lovers enjoy more than 6 hours per day, but need regular water to endure the heat.
• Part Shade: 3 - 6 hours of sun each day, preferably in the morning and early afternoon. The plant will need some relief from the intense late afternoon sun, either from shade provided by a nearby tree or planting it on the east side of a building.
  Dappled Sun: Dappled sunlight is similar to partial shade. It is the sun that makes its way through the branches of a deciduous tree. Woodland plants and underplantings prefer this type of sunlight over even the limited direct exposure they would get from partial shade.
• Full Shade: Less than 3 hours of direct sunlight each day, with filtered sunlight during the rest of the day. Full shade does not mean no sun.
