What is a <strong>Ground</strong> Cover?<br />

• Essentially it is any low-growing plant that can be<br />

used in the landscape to cover bare ground.<br />

• It is a functional name as a plant may function as a ground<br />

cover for one person be used as a bedding plant for<br />

someone else.<br />

• They can be used to fill in between adjacent accent plants<br />

or to frame/border a grouping <strong>of</strong> similar shrubs.<br />

• <strong>Ground</strong> covers are <strong>of</strong>ten thought <strong>of</strong> as having a creeping<br />

or climbing habit, but there are many low growing plants<br />

which serve this purpose.<br />

• They probably should be less than 3 feet tall.<br />

• Probably should not include annuals or short lived<br />

perennials.


How do they benefit the homeowner?<br />

• Can provide a surprising amount <strong>of</strong> energy savings<br />

5-7 months per year.<br />

• Evaporative cooling can lower the temperature<br />

immediately surrounding the plants by as much as<br />

9 degrees F. and can be as much as 25 degrees F.<br />

cooler than paved surfaces.<br />

• Water savings plus fertilizer and pest control savings<br />

can be significant.<br />

• Some will grow in deep shade others in full sun – some<br />

grow in both.<br />

• Apart from their value as a filler and weed suppression,<br />

many ground covers have inherent ornamental value (showy<br />

flowers attractive foliage).


Perennial peanut<br />

• Arachis glabrata<br />

• Non-native<br />

• Zones 8-11<br />

• Height – ½ to one foot<br />

• Width – one to eight feet<br />

• High drought tolerance<br />

• Make sure to purchase rhizomal type – Ecoturf<br />

or Needlepoint which are drought tolerant.<br />

• Stoloniferous type like “Repens Golden Glory”<br />

are commonly for sale in central <strong>Florida</strong>.<br />

• Flowers summer thru fall.


Perennial Peanut<br />

Advantages<br />

• Requires little to no fertilizer or water.<br />

• Does not need regular mowing.<br />

• Forms a dense mat <strong>of</strong> rhizomes when established.<br />

• Very few to no pests and diseases.<br />

Disadvantages<br />

• Does not grow well in shade and does not traffic well.<br />

• Does not take cold.<br />

• Takes an extended period to establish particularly<br />

from sprigs may give weeds a chance establish.<br />

only a few registered herbicides.<br />

• Basagran and Cadre DG will control yellow nutsedge and<br />

• some broadleaves.<br />

• Fusilade, Poast, Select and Prism are labeled for grassy<br />

weed control.


Pinto peanut – Arachis pintoi.<br />

Locally called Repens Golden Glory.<br />

Forms roots at the nodes, does<br />

not form rhizomes as does Arachis<br />

glabrata – Ecoturf/Needlepoint.<br />

Studies around the world<br />

indicate that Pinto Peanut<br />

is more prone to have winter<br />

kill, spider mite damage and<br />

have nematodes issues. Logic<br />

would dictate that they are<br />

also less drought tolerant.

A couple <strong>of</strong> possibilities as ground covers:<br />

• Peace lilies<br />

• Spider plant


Peace Lily - Spathiphyllum cochlearispathum<br />

• Central and possibility south <strong>Florida</strong><br />

• Not known to stand cold temperatures.<br />

• Medium to fast growth.<br />

• Filtered light to full shade.<br />

• Reach 3-4 feet tall.<br />

• Produces a pr<strong>of</strong>usion <strong>of</strong> white flowers.<br />

• Some maintenance required to remove spent flowers.<br />

• Require minimal amounts <strong>of</strong> water and fertilizer.<br />

• Generally pest and disease free.<br />

• A number <strong>of</strong> landscapes in the Lakeland area have<br />

these plantings.<br />

• The following photos are peace lilies which have<br />

survived outside winters at a Lakeland residence<br />

under a large sand live oak tree for 3-4 years.


The parents <strong>of</strong> these plants<br />

were kept in pots for many<br />

years in a lanai in which the<br />

temperature did not go<br />

below freezing. They were<br />

transplanted to the outside<br />

landscape about 3 years ago.<br />

have shown little to no cold<br />

damage.<br />
