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 />
