Distribution

Distributed from New Jersey, west to Wisconsin and Kansas, and south to Texas and Florida.[1]

Ecology

Habitat

This species has been observed growing in dry woods, hammocks, along the edges of river banks, floodplains, and streams, slash pine-palmetto woodlands, and pine woodlands. It is also found in areas disturbed by humans such as roadsides, ditches, and clearings. Thriving in light from shade to full sun, this species grows in moist sands or drying loamy sands and has even been recorded to grow in water along edges of springs.[2]

Associated species include oak, beech, cypress, slash pine, saw palmetto, sweetgum, Cyrilla, Pinus taeda, Pinus echinata, Quercus nigra, Trichostema dichotomum, Helianthus angustifolius, Agaratina aromatica, Solidago odora, S. nemoralis, Pityopsis aspera var. adenolepis, Sorghastrum nutans, Andropogon virginicus var. virginicus, Chamaecrista fasciculata, Chamaecrista nictitans, Eupatorium hyssopifolium, Liatris graminifolia, Rubus cuneifolius,[2] and Hibiscus grandiflorus[3]

Phenology

C. coelestinum has been observed flowering from June through January with peak inflorescence in October.[2][4] Spreads by long, underground rhizomes.[5]

Seed dispersal

Seeds are dispersed by wind.[1]

Fire ecology

This species can grow in areas that are regularly burned.[2]

Use by animals

Caterpillars of the moths Haploa clymene, Phragmatobia lineata, Carmenta bassiformis, and Schinia trifascia eat on the foliage.[5] The bitter foliage defers mammalian herbivores.
