Description
Perennial that grows 6-12 inches in height including the elongated spike of pink or rosy flowers. Flowers average width of less than half an inch.[1]
Distribution
Ecology
Habitat
This species has been found growing within calcareous glades, upland pine woods, longleaf pine-scrub oak sand ridges, savannas, and sandhill communities (Deyrup et al 2002, FSU Herbarium). It has also been observed growing in swales of slash pine plantations (FSU Herbarium). P. grandiflora responds negatively to soil disturbance by agriculture in Southwest Georgia.[2]
Phenology
This species has been observed flowering and fruiting in May (FSU Herbarium).Cultivated plants may be in continuous bloom from earliest spring to late autumn, or even year round in southern Florida.[3]
Seed dispersal
This species is thought to be dispersed by ants and/or explosive dehiscence. [4]
Seed bank and germination
Fire ecology
Flowers within two months of burning in early summer (Robertson).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Polygala grandiflora at Archbold Biological Station (Deyrup 2015):
Megachilidae: Anthidiellum notatum rufomaculatum
Use by animals
Deyrup observed this bee, Anthidiellum notatum rufimaculatum, on P. grandiflora (Deyrup et al 2002).Lilliputian moths pupa have been observed consuming the seeds inside the capsules.[5]
