Pentas lanceolata
Egyptian star cluster, an old-fashioned upright shrub, is hard to acquire these days. Egmont Seeds does a colour mix called ‘Graffiti‘ in purples and whites, and though compact and attractive, these seed-grown plants can be less long-lived than the original tall, red species.
Pentas are not hardy shrubs, and need milder climes and a well-drained soil with plenty of sun where they will flower all year.
