"

A widely distributed tropical/subtropical shrub that attracts multiple pollinators, p. carolinensis has several traditional medicinal and cultural uses. It has prolific wind dispersed achenes and is considered invasive outside its natural range. Easy to cultivate and hard to kill, caution should be used when considering this plant for your garden.

Landscape
It is a successional nurse crop and can be used for re-vegetation, dune stabilization, and for erosion control. It is considered invasive outside of its natural range, competing with native plants for space and resources.
Cultivation
As an early successional species it is shade intolerant and commonly thrives in disturbed habitats. Tolerant of salt and compaction, it grows in areas with at least 1000 mm of annual rainfall or where there is sufficient groundwater levels and requires bare, wet soil in which to germinate.
Shape
An erect shrub. Older plants are held upright by flexible lateral roots and it can be sparsely branched.
Growth
Fast
ID Characteristic

It grows from around sea level to an elevation of 1000 m.
Bark/Stem Description
The basal stem can be up to 6 cm in diameter. P. carolinensis stems are glandular tomentos and moderately soft and brittle.
Leaf Description
