Hawaiian Woodrose Plant Care

Hawaiian Woodrose (Argyreia nervosa) belongs to the Convolvulaceae family within the Argyreia genus. Hawaiian Woodrose is native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Hawaiian Woodrose is also known as Elephant Creeper, Silver Morning Glory, Violets.

Hawaiian Woodrose displays a vining, spreading growth habit, reaching up to 15 ft tall with a spread of approximately 5 ft. Hawaiian Woodrose produces showy trumpet-shaped flowers in various colors.

Leaf size: approximately 6 inches.

Argyreia nervosa requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Hawaiian Woodrose thrives in full sun to partial shade.

Argyreia nervosa grows best at temperatures of 65–85°F. Hawaiian Woodrose prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added organic matter. Good drainage is essential for Hawaiian Woodrose to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hawaiian Woodrose every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Repot annually in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Hawaiian Woodrose can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to wedgeleaf sweetwood plant care, which shares the same genus.
