Hibiscus sabdariffa is a tropical herbaceous plant (or subshrub in warmer environments) known commonly as Roselle, Jamaican Sorrel, or Florida Cranberry. It features upright, bushy stems with deeply three‑ to five‑lobed leaves. The foliage emerges simple and single‑lobed, maturing into the characteristic lobed form as the plant grows. The flowers are pale, ranging from creamy‑white to yellow, with a dark red centre at the base of each petal, surrounded by a stout calyx. As the fruit matures, the calyx becomes fleshy and deep crimson red, expanding significantly in size.
In the UK, growing Hibiscus sabdariffa indoors requires focusing on light, moisture, and warmth. Given its tropical origin and preference for long, warm growing seasons, this plant makes it perfect for growing indoors, provided you can replicate those conditions in containers or greenhouse settings.
Native to: West Africa, with cultivation spreading to Asia, the West Indies, and beyond.
Water: Keep the growing medium consistently moist but well‑drained. Avoid waterlogging by ensuring good drainage.
Light: Full sun is ideal. The plant does not perform well in shade, if grown indoors, provide a bright, sunny position.
Humidity: As a tropical species, it thrives in warm, humid conditions. Indoor humidity should be kept relatively high for best results; humidifying options or placement in naturally more humid areas (e.g., near a humidifier) are beneficial.
Temperature: Roselle prefers temperatures above around 15 °C (60 °F).
