Roselle Seeds, Hoa Bụt Giấm, Asian Sour Leaf Red Sorrell Hibiscus sabdariffa

Roselle, also known as Hibiscus sabdariffa, is a tropical plant that is primarily grown for its vibrant red calyces, which are used to make a popular beverage known as hibiscus tea or sorrel. Roselle seeds are the seeds of this plant and are used for various culinary and medicinal purposes. Here's how to grow and use roselle seeds:

Growing Roselle:

1. Climate: Roselle thrives in tropical and subtropical climates but can be grown as an annual in temperate regions. It requires plenty of sunlight and warm temperatures.

2. Planting: Start by obtaining roselle seeds, which can be found at garden centers or online. You can also collect seeds from mature roselle plants. Plant the seeds directly in the ground or in pots after the last frost date in your area. Space the plants about 3 feet apart, as they can grow quite large.

3. Soil: Roselle prefers well-drained, loamy soil with a slightly acidic to neutral pH (around 6.1 to 7.0).

4. Watering: Keep the soil consistently moist but not waterlogged. Roselle plants are relatively drought-tolerant once established, but they thrive with regular watering.

5. Fertilization: Apply a balanced fertilizer or compost to the soil at planting time and again during the growing season.

6. Pruning: Prune the plant to encourage bushier growth and remove any dead or diseased branches.

7. Harvesting: Roselle typically starts producing calyces (the part used for tea) about 3-4 months after planting. Harvest the calyces when they are bright red and fully developed. Simply cut them off the plant.
