Brighamia (common name: Hawaiian palm or cabbage on a stick) is a small genus of flowering plants in the Campanulaceae family, best known for Brighamia insignis. These succulent, rosette-forming perennials have thick, fleshy stems topped by a crown of narrow, straplike leaves and produce tubular, trumpet-shaped flowers in shades of yellow or cream. Native to the Hawaiian Islands, they evolved for pollination by native hawk moths and are critically endangered in the wild due to habitat loss and loss of pollinators.

Light

Bright, indirect light; tolerates some direct morning sun. Indoors place near an east- or south-facing window with a sheer curtain.

Water

Allow top 1–2 inches of soil to dry between waterings. Water thoroughly, let excess drain. Reduce watering in winter.

Humidity & Temperature

Prefers moderate to high humidity; mist occasionally or use a humidity tray. Keep temperatures between 65–80°F (18–27°C). Protect from drafts and cold below ~50°F (10°C).

Soil & Potting

Use a fast-draining, gritty cactus or succulent mix. Repot only when rootbound, every 2–3 years.

Fertilizer

Feed lightly during the growing season (spring–summer) with a balanced, diluted fertilizer every 4–6 weeks.

Special notes

Brighamia enjoys bright, airy conditions and sparse watering; it's sensitive to overwatering and cold.
