MAIN INDEX | Retention Ponds | Aquascaping | Plants and Aquascaping |
|
Many Florida counties promote and even require aquascaping of necessary man-made retention ponds.
Aquascaping may be used in a variety of settings, such as in projects to beautify
natural and man-made lakes and water retention ponds, especially in urban areas. The
aquascaped
shoreline of Lake Butler (left picture) enhances the value of lakeside homesites of
central
Florida; the aquascaped retention pond in a shopping center in Tampa (right
picture)
provides wildlife habitat and eye-candy in a high-traffic urban setting.
Retention and stormwater management ponds are a permanent fixture on much of
Florida's
landscape. Without them, Florida would not be able to support its growing population safely or
efficiently.
Many areas of Florida that are flood-prone are also paved with asphalt or covered in concrete,
thus preventing rainwater from absorbing into the ground to replenish our aquifers. After a heavy
rain, retention ponds
collect excess water as it runs off of the paved areas. Another function of retention ponds
is to catch and trap pollutants, preventing their runoff into natural waterbodies.
Runoff water
gathers oil, gas, pesticides, heavy metals, fertilizers, bacteria, and nutrients as it flows
over roadways and parking lots. These pollutants could cause serious harm if they flowed directly
into waterbodies
without any filtration or decomposition.

Though retention ponds are a necessary
part of Florida's landscape, they often look unnaturally
bleak. What's more, these man-made ponds are easily invaded by non-native plants, and are
further uglified by algae blooms.
But there are ways to make these ponds more visually appealing while maintaining their
utilitarian functionality.
While the main goal of aquascaping retention ponds is to beautify the constructed
pond and its shoreline and to hide the runoff areas, aquascaping also aids in pollutant
filtration, controls erosion of the pond banks, attracts
wildlife and increases much-needed wildlife habitat in urban settings, and helps control
invasive non-native plants.
Even though most retention ponds cannot be used for recreational purposes, aquascaping allows
these wet places to contribute to the aesthetic value of their surrounding areas. A lush
pondscape breaks up the seemingly endless view of concrete and asphalt in highly developed
areas.
PLANTS AND AQUASCAPING
Instead of settling for generic, uninspiring retention ponds surrounded by
chain-link fencing, aquascaping with Florida's native aquatic plants offers a glimmer of
beauty that stands out against the gray and black of roads, parking lots and urban development.
As in gardening and landscaping, aquascaping must be maintained. When aquascaped
waters are left untended, non-native invasive plants will take over. In this aquascaped waterway,
water hyacinth plants, brown with decay, have been treated with herbicides to make room for the
native plantings.
Given Florida's abundance of native aquatic plants, and except for the actual hard labor
involved, it is not so difficult to create a beautiful and unique man-made pond that also achieves
its intended water management functions.
| Get to Know Your Aquascaping Possibilities! Since there are varying water levels in retention ponds, different types of vegetation need to be planted according to water depth. In the deeper parts of the pond, submersed aquatic plants such as baby's-tears, pondweeds, bogmoss and eelgrass will help keep the water clear and provide oxygen to the water. The floating-leaved plants such as water lilies, cow lilies, and water shield offer colorful, fragrant flowers. In more shallow water emersed aquatic plants such as duck potato, lemon bacopa, and American lotus add color and beauty. As well in the shallow areas, grasses such as maidencane, sedges such as bulrush, and rushes such as spikerushes, provide fish with hiding places and mosquito-eating dragonflies with habitat. Trees such as swamp tupelo, swamp dogwood and lobolly bay provide birds and mammals with food sources. |
However aquascapers tend to use the same very few types of plants in most of their designs, and don't branch out to discover what other plants are good-looking, suitable and available.Instead, why not develop your own aesthetic, look at other plants, large and small, with a fresh eye, and create a uniquely personal aquascape.Too many retention ponds are aquascaped using just a very few species, such as pickerel weed (Pontederia cordata); blue flag (Iris species); the orange canna hybrids (Canna flaccida) and duck potato (Sagittaria lancifolia). While these native plants certainly carry out their intended function as decoration, their overuse causes many aquascapes to have the same uniform look.
Utilizing a variety of plants would offer more to wildlife in the way of food and shelter, would provide better defense against invasive plants, and would appear to be more natural-looking.
Aquatic nurseries offer a greater variety these days - find plants that appeal to you and specify them in your aquascape plan.

Have a look at Florida's native aquatic plants and see just how creative you can get at designing your own aquascape. This page includes pictures of aquatic and wetland plants that you might consider (scroll down to click on the grasses, sedges, rushes, floating-leaved, submersed and emersed plants). Choose native plants you feel would look good in your aquascaping project (don't forget the small ones!) and call the nurseries and vendors to order them.Find nurseries and vendors of native Florida aquatic plants on another page of this web site.
Plants for Freshwater Shores, Streams and Ponds, a Pinellas County Extension publication, includes basic planting requirements for a nice selection of Florida native aquatic plants which may be used in aquascaping.
