Opinion
"
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.

| 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 sufficient groundwater levels. Requires bare, wet soil in order to germinate. |
| Shape |
| An erect shrub. Older plants are held upright by flexible lateral roots and it can be sparsely branched. |
