Culture Notes Tolerant of a wide-range of soil types, Pentas prefers fertile, well-drained soils, regular moisture, and will grow quickly in full sun or light shade. Plants will flower fairly well with as little as 2 to 3 hours of sun each day. Plants can be dug, cut back, and stored in a container of soil over the winter in climates that receive freezing temperatures. Water occasionally to keep roots from drying out and replant and fertilize in the spring. Heavy mulch applied over the crown of plants cut back to the ground will help plants survive winter in hardiness zone 8. In most years, plants regrow from the partially buried stems in the spring. Plants can be clipped as a hedge but flower production will suffer. They are best left unclipped so flowers are free to develop on new growth. Plants serve as butterfly nectar sources.
