10 Seeds Roselle Hibiscus sabdariffa Calyces Tea Garden Ornamental Annual

Roselle is a tropical hibiscus grown for its striking crimson calyces and lobed green foliage, adding a bold tropical look to warm-season gardens and containers. The fleshy red calyces develop after the pale yellow flowers fade and are the part most often harvested for culinary use.

The young leaves and calyces are used in teas, jams, jellies, and syrups, while the plant itself works well as a tall annual accent in beds and large pots. It grows quickly in warm weather, reaching shrub-like size in a single season and thriving in full sun with consistent moisture.
