Overview
Pentas, or Egyptian star flower, is a tender evergreen shrub grown as a summer annual in most regions and as a small flowering shrub in frost-free climates. It produces domed clusters of five-petaled, star-shaped flowers in red, pink, lavender, and white.
It blooms reliably through heat and humidity from late spring to frost and is one of the best pollinator plants available, drawing butterflies, bees, and hummingbirds in droves.
How to identify it
- Habit: Bushy and upright, 1-3 ft as an annual, larger as a shrub
- Flowers: Rounded clusters of small, 5-pointed star-shaped blooms
- Colors: Red, pink, rose, lavender, white
- Leaves: Lance-shaped, deeply veined, slightly fuzzy, green
- Bloom time: Late spring through frost
Care & growing

Water: Keep evenly moist; avoid both drought stress and waterlogging.
Soil: Rich, well-drained soil.
Temperature: Loves heat and humidity; not frost-hardy.
Feeding: Feed regularly through the growing season for continuous bloom.
Propagation: From cuttings or seed. Deadheading spent clusters encourages more flowers.
Habitat & origin
Native to East Africa, the Arabian Peninsula, and surrounding tropical regions, where it grows as an evergreen shrub.
It is grown worldwide as a warm-season bedding and container plant for its pollinator appeal, and as a landscape shrub in tropical and subtropical gardens such as Florida and the Gulf Coast.
Uses & benefits
Ornamental: A standout in butterfly gardens, beds, borders, and containers, valued for long bloom and bright color.
Ecological: One of the most effective nectar plants for attracting butterflies and hummingbirds.
