Introduction

A ground cover is any low-growing plant that can be used to cover an area in the landscape. Many woody and herbaceous plants fulfill this role. And as part of passive, energy-saving landscaping (enviroscaping), ground covers can provide a surprising amount of residential energy savings during Florida's 5 to 7 months of high temperatures.

Plants release water through pores in their leaves by transpiration. As warm air passes over leaf surfaces, heat is absorbed by the water, which then evaporates and lowers the temperature of the air. Called evaporative cooling, this interaction lowers air temperature immediately surrounding vegetation by as much as 9°F (5°C). The greater the leaf-surface area in the landscape, the greater the cooling effects.

Paved surfaces around the home contribute substantially to summer heat loads. These surfaces absorb the sun's heat or reflect it back into the

immediate environment, increasing the amount of discomfort experienced by people during the day. Paved areas also store heat during the day, keeping temperatures high around the home even after sunset. Temperatures over ground covers can be 15 to 25°F (8.3 to 14°C) lower than over asphalt or concrete.

Turfgrass

Turfgrass qualifies as a ground cover. Many people find great aesthetic appeal in sweeping, well-manicured green lawn. On the practical side, no other plant can withstand as much foot traffic as turf. Maintaining a lawn in prime condition, however, requires energy-intensive mowing, regular fertilization, irrigation, and, at times, expensive pest and disease control. A quarter-acre lawn requires four times the total energy costs of a landscape of the same size that has a one-sixteenth-acre lawn with the remaining area planted in low-maintenance vegetation (Parker, 1982).

As fossil-fuel prices rise, so do the costs of fertilizing, watering and mowing a lawn. Some

turfgrasses, like bermudagrass, do best with 218 pounds of nitrogen per acre per year, a 7.2 million Btu investment. A medium fertilization level of 174 pounds of nitrogen per acre per year (5.8 million Btu) is recommended for St. Augustine lawns. At the lowest fertilizer level, centipede lawns need 87 pounds of nitrogen per acre per year (2.9 million Btu). Choosing centipede instead of St. Augustine can save 29 million Btu of energy (equal to the energy in 232 gallons of gasoline) per acre over 10 years (Whiffen, 1993).

On average it takes a quarter of a gallon of gasoline (31,250 Btu) [combustion engine] or 1.4 kwh (15,000 Btu) [electric motor] to mow a quarter-acre lawn. Depending on location and fertilizer frequency, the lawn probably gets mowed 10 to 20 times a year. To minimize energy and time inputs, only cut one-third of the grass blade at a time and don't over fertilize (Whiffen, 1993).

Water quality and availability have become important issues in Florida. Depending on location, Florida lawns need 20 to 35 inches of water from irrigation per year. Over 8 million Btu of energy are required to supply water to a one-half-acre lawn in Orlando. If a one-half-acre yard is landscaped so one-fourth is lawn and the rest is planted with ground covers, shrubs and trees in mulched areas, over 4 million Btu of energy can be saved annually along with 224,000 gallons of water (Whiffen, 1993).

Alternatives to Turfgrass

There are ground covers besides turf that require a fraction of the upkeep and are frequently more adaptable to a wider range of environmental conditions. For instance, turf does not grow well in dense shade and is difficult to establish in extremely wet or dry areas. There are several other ground covers adaptable to such problem situations. Lily turf (Liriope muscari, L. spicata) and mondo grass (Ophiopogon japonicus) are excellent, low-maintenance performers in dense shade. Lippia (Lippia nodiflora) has an outstanding tolerance of wet soils. Golden creeper (Ernodea littoralis), a native seacoast species, is highly tolerant of both salt and drought. Proper selection can minimize irrigation, fertilization and mowing after ground covers are established.

Herbaceous and woody ground covers offer a variety of colors and textures in contrast to the uniformity of turf grass. They can unify the home landscape and complement trees and shrubs.

Establishment of Ground Covers

Generally, ground covers are established in two years, although some species require slightly more or less time. During this period, a regular program of irrigation, fertilization and weed control ensures strong, rapid growth. Mulch aids water retention in new plantings and helps the spread of ground covers that root along their stems. Once established, many ground covers need only an occasional trimming to keep them tidy and within their designated area.

Selecting a Ground Cover

The accompanying table will help home gardeners and landscape professionals select ground covers appropriate for south Florida site conditions. Each species has the expected height of the mature plant, along with the color of both leaves and flowers. The drought-tolerance ratings refer to Florida conditions only and should be interpreted as follows - High: survives without supplemental irrigation after establishment; Moderate: requires supplemental irrigation during very dry periods to maintain satisfactory appearance and health; and Low: little or no drought tolerance. Drought tolerance also varies with soil and other environmental conditions. 'X' indicates whether a particular ground cover can be used in each of five landscape situations. Finally, the "Comments" section has special notes about each species.

Turf grass is still the best ground-cover choice for outdoor areas that have heavy recreational use. For situations where turf serves no practical purpose, alternative ground covers perform equally well or better at a fraction of the energy input required by a lawn.
