Ecology
Habitat
It is extremely vulnerable to disturbance. One reason for this might be that it relies heavily on native species of ants for dispersal.[1] It can be found in longleaf pine communities.[2] It can also be found in sandhill communities.[3] It has been found on the edges of sandy oak-palmetto scrub, clobbered, cutover flatwoods, and pine-turkey oak flatwoods and sand ridges.[4] It has also been found to grow along disturbed areas like the wooded edges of powerline corridors. Growing in either moderate shade to full sun, this species grows in drying sandy loam in the uplands. C. argyranthemus responds both negatively and positively to soil disturbance by roller chopping in Northwest Florida sandhills.[5] However, it responds negatively to soil disturbance by agriculture in Southwest Georgia.[6]
Associated species includes Crotonopsis, Paronychia, Tetragonotheca, Berlandiera, and Onosmodium.[4]
Phenology
It is a summer forb.[1] This species has been observed to flower from March to October with peak inflorescence in May and June; it has been obsereved to fruit from April to September.[4][7]
Seed dispersal
Seeds have elaiosomes, and can be dispersed by ants such as fire ants.[2] The seeds can also be dispersed explosively.[1] Three of the ballistic euphorbs (C. stimulosus, C. argyranthemus and S. sylvatica) produce seeds with elaiosomes and all of the ballistic species are collected by ants, in particular Pogonomyrex badius Latreille (Long and Lakela 1971; N.E. Stamp and J. R. Lucas, personal observation).”[3] This species is thought to be dispersed by ants and/or explosive dehiscence. [8]
Fire ecology
This species is fire tolerant and is included in the flowering plant survery – post burn – in Heuberger’s study.[9]
Pollination
Pollinated mostly by small bees.[10]
Use by animals
Ants are an agent of seed dispersal.[2] C. argyranthemus is an important game food plant: it is consumed by doves, quail, and deer.[11] It is the larval food plant for the goateed leafwing butterfly. It produces a milky sap to help defend from herbivory.[10]
