This iris and I. hexagona were considered to be a single species until recently.  I. savannarum is the most common iris species in Florida. Moist wildflower garden. Sometimes grown under the drain for an air conditioner. Excellent as a wetland edge flower.

As the name infers, the flowers of this plant open at night. Once the sun starts coming up, the flowers will begin to wilt. By night fall the flowers are spent. Can be grown as a groundcover but probably best welcomed into a multi-species planting where its flowers bring color to an planting of low greenery.

Specimen plant, screen plant, understory tree/shrub.

The plant is listed as Endangered by the FDACS.  Please acquire from reputable nurseries with appropriate permits for propagating and selling this species. Can be a specimen tree or use in a fairly bright understory. Its irregular branching pattern and large leaves make it best suited to fairly large yards.

To avoid introgression with other H. debilis subspecies, do not grow them in a common garden. Ground cover in sandy, open environments.

Can be pruned either as a small tree or a large shrub. Can also be used as a hedge.

Seeds float and can be dispersed by water. Noted as a sand stabilizer being one of the first plants to colonize active dunes. Pan-tropical. Makes a nice groundcover in an informal dry yard. In nature, it is an important stabilizer of beach dunes.

Difficult to transplant. Clonal. May be used as a hedge and takes to pruning.
