What its natural habitat tells you

Flower color. Usually orange to yellow-orange; yellow forms and yellowish to vermilion tinges are also recorded by the source. Source

Preferred light. Prefers full sun. Partial shade is a recorded tolerance, rather than the preferred flowering condition. Source

Safety has not been reviewed for this plant; check toxicity and thorns before planting.

Leave its deep taproot undisturbed. Avoid wet soil; seed-grown plants may need several years to flower. NC State Extension
