Taxonomic notes

Synonym: Garberia fruticosa (Nuttall) A. Gray

Description

A description of Garberia heterophylla is provided in The Flora of North America.

G. heterophylla is a perennial species that reaches a height of 4 to 8 feet. The obovate leaves are alternately on the vertical stem.[1]

Distribution

It is native to Florida.[1]

Ecology

Habitat

In the Coastal Plain in Florida, G. heterophylla occurs in sand pine-oak scrub ridges. [2] Associated species includes Quercus virginiana and Pinus clausa. [2]

Phenology

Fruits November through December and flowers October through December. [2]

Seed dispersal

Seeds are dispersed by wind. [3]

Seed bank and germination

Smoke does not stimulate germination. [4]

Fire ecology

Carrington (1999) found G. heterophylla to be a strong resprouter post-fire, with a high percentage of individuals flowering. This study also found seedlings were established between 4 to 16 months post fire. This contradicts Weekley and Menges (2003), who found that survival was lower for burned individuals than for unburned individuals, suggesting G. heterophylla was a weak resprouter.
