Brief Description

An annual or perennial shrub known for its lobed green leaves often featuring reddish veins and stems. It is primarily grown for its edible, fleshy red calyces that develop after the flowers fade.

Care Instructions

Plant in a sunny spot with at least 6 hours of direct light. Use well-draining soil and water regularly to keep the soil moist but not waterlogged. Apply a balanced fertilizer during the growing season to encourage flowering.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Full sun, 6 to 8+ hours per day

Watering

Moderate to high; requires consistent moisture. Drought tolerant once established but produces better calyces with regular watering. Avoid soggy roots.

Soil

Rich, well-draining sandy loam with a slightly acidic to neutral pH (6.0-7.0)

Hardiness Zone

9-12 (grown as an annual in cooler climates)

Growth Habit

Upright, woody-based subshrub reaching 5 to 7 feet in height and 3 to 4 feet in spread.

Bloom Season

Late summer to fall; flowers are pale yellow to cream with a dark maroon eye, followed by the distinctive bright red fleshy calyx.

Toxicity

Generally non-toxic to humans; however, excessive consumption of tea may affect some individuals. Generally considered safe for pets, but always monitor for individual reactions.

Propagation

Propagated by seed (best started indoors 6-8 weeks before last frost) or by stem cuttings in early summer.

Common Pests & Issues

Susceptible to root-knot nematodes, aphids, and mealybugs. In wet conditions, it may develop mildew or root rot.

Similar Species

Okra (Abelmoschus esculentus) has similar leaves and flowers but produces long green seed pods. Other Hibiscus species lack the fleshy edible red calyx of H. sabdariffa.
