Hibiscus radiatus

Hibiscus radiatus | Monarch Rosemallow, October Rose, Ruby Hibiscus, Rayed Hibiscus

Hibiscus radiatus, is often called 'October Rose' because of its flowering season in the northern hemisphere. This is one of the 'cannabis leaved' types of Hibiscus as can be seen in the photo. This beautiful Hibiscus can grow to 10' by bloom time and is covered in deep burgundy colored blooms (color may vary). This plant is perennial in USDA zones 9-11 or a self-sowing annual in other zones. Prefers full sun and well drained soil (but will grow in the shade). Also an excellent plant in drought conditions ―it will grow almost anywhere with little care. Caution: In certain areas with favorable conditions, this species becomes weedy. As with many species in Hibiscus section Furcaria, the stems and seed pods have small spines.

Historical Reference: Hibiscus Radiatus, vor. FLORE PURPUREO, (Purple-flowered rayed Hibiscus). — Common in the Calcutta Gardens, but raised from seeds received from Mr. Wilson, superintendent "of the late Botanic Garden at Bath", in the Island of Jamaica. I say late, an awful avalanche of stones having recently overwhelmed the Garden.
