Grows well well north of its native range.  Documented in very southern counties with an outlier in Martin County -- that outlier is also unique in that it was collected near a cypress dome. Closely related to corn, this species has been crossed with maize to produce a corn that is resistant to Helminthosporium turcicum, the fungus that causes northern leaf blight  (Wikipedia). Listed as Threatened in Florida. Informal borders.

Specimen tree, street or parking lot tree.

The author treats this as a friendly weed. Pull them if where there is something more desirable. Back of a wildflower garden in a casual setting. Grown en-masse, this plant can be used as a temporary groundcover.

Use along streams or edges of retention areas. Can be a screen or specimen tree in moist areas. Blooms better in moderate to high light settings.

The cells of the stamen hairs of some Tradescantia are colored blue, but when exposed to sources of ionizing radiation such as gamma rays, the cells mutate and change color to pink; they are one of the few tissues known to serve as an effective bioassay for ambient radiation levels. Border plantings.

Some literature sources suggest that this species may have some salt tolerance as it apparently grows along the upper edges of some salt marshes, but so far as we have seen recorded, not in Florida. Moist/wet wildflower garden.

Specimen shrub. Fine foliage. Does well adjacent to structures or woods.

This is one of Florida's most showy and most under-appreciated wildflowers. Look for it along disturbed roadsides in mid-late winter and early spring. This is a personal favorite of one of the authors -- it grows and bloom early and attracts lots of insects.  The only issue is the prickles, so I wear gloves when weeding around it.  It reseeds readily so long as there is good sun and  bare ground where the seeds land. Don't let the name fool you, this is a Florida native. Wildflower garden. Roadside wildflower areas. This plant blooms from late winter into spring displaying its large flowers when little else is blooming in the garden.

Small specimen plant in wet areas.  Does well in bog gardens and rain gardens or bioswales.

Wildflower garden, groundcover

Understory tree, use as a background plant or screen.

Multi-stemmed. A single stem is a curiosity. A large multi-stemmed plant is a long-blooming wonder. Despite the common name, this species has sweet-smelling flowers. The range of this species extends from central Texas east and north into southern New England.  It is represented in Florida by a few isolated occurrences in northwest Florida. Specimen shrub

Fruit is a white berry with indigo pulp. Specimen plant. Shrub border or foundation plant. Will tolerate shearing. Valued for its shiny foliage and dense branching.

Used for wetland restoration. Attractive for planting in surface water management ponds.

The herbarium specimen from Polk County almost certainly has a wrong location.  Lithia is in Hillsborough County and the most likely translation of a wrongly written latitude and longitude is also in Hillsborough County -- but the exact location would have been agricultural in 1962. Hedges, back borders. Blooms in summer.

Trellis or fence

In a managed garden, gamagrass can be trimmed back at the end of winter. Hedge, foundation planting, individual large grass clump, background screen for a flower garden. Rain garden or bioswale.

Red/orange fall color is excellent. Leaves have three separate shapes: ovoid, tri-lobed, or mitten-shaped (left or right). Mature trees tend to have fewer lobed leaves. Subject to laurel wilt disease.  Please be careful not to move firewood or dead wood around.  Best not planted in areas where laurel wilt is present. A relatively small tree that often forms thickets. Best used in informal settings.

The Emerald Ash Borer (Agrilus planipennis)is a very destructive wood-boring beetle native to Asia. It was discovered in North America in July 2002, and has become established in Michigan, New York, Ohio and Ontario (Canada). Millions of ash trees have been killed in the northeastern US. Although the borer has not been detected in Florida (Dec. 2011), the presence of ash trees and the ongoing movement of wood, trees and cargo into the state make Florida an area where the beetle could potentially become established. Your help is needed to detect possible infestations so they can be quickly eradicated...if you see it, contact the Florida Division of Forestry. Appropriate for edges of lakes and ponds. Will also grow as a shade tree in uplands, but white ash has better form. Can be used in settings with soil disturbance.
