Safety Overview
1.Pentas Red — Overview
Pentas lanceolata 'Red', commonly known as Egyptian Starcluster or simply Pentas Red, is a captivating and robust perennial belonging to the Rubiaceae family. Native to tropical East Africa and Arabia, this specific cultivar is highly prized for its exceptionally vivid, intense red flower clusters. The plant typically forms a bushy, upright mound, generally reaching a height and spread of 1 to 3 feet (30 to 90 cm).
Its foliage consists of medium to dark green, lance-shaped leaves, which are often slightly hairy, providing a rich, verdant backdrop that accentuates the brilliant blooms. Each inflorescence is a dense, rounded cluster composed of numerous small, five-petaled, star-shaped florets, creating a continuous display of color from spring through fall, and often extending into winter in frost-free environments. Pentas Red is a highly adaptable plant, thriving in full sun and requiring well-drained soil conditions.
Its continuous blooming habit and low-maintenance nature make it an outstanding choice for various horticultural applications, including borders, mass plantings, containers, and as a vital component in gardens designed to attract pollinators such as butterflies and hummingbirds. While primarily cultivated for its ornamental beauty and ecological role, its robust growth habit and extended flowering period are key characteristics.

11.Pentas Red — Growing Guide
- ✓Site Selection — Plant Pentas lanceolata 'Red' in a location that receives full sun, ideally six or more hours of direct sunlight daily, to ensure prolific blooming.
- ✓Soil Requirements — Thrives in well-drained soil; sandy loam or loamy soil enriched with organic matter is ideal. Avoid heavy, waterlogged conditions.
- ✓Planting — Best started from rooted cuttings or purchased as nursery plants. Space plants 1 to 2 feet apart to allow for mature spread.
- ✓Watering — Provide consistent moisture, especially during dry periods and hot weather, as young plants establish. Established plants show moderate drought tolerance.
- ✓Fertilization — Fertilize regularly during the active growing season (spring through fall) with a balanced liquid fertilizer to support continuous flower production.
