These flowers are celebrated for their long vase life and are a favourite for dried and fresh floral arrangements. Native to arid climates, they thrive in South Africa’s sunny conditions and are perfect for water-wise gardens.

Care & Handling

Vase Life

• Expected vase life: 10–14 days when fresh, indefinite when dried.

Handling Tips

1. Harvest early in the morning when blooms are half-open for the longest life.
2. Recut stems at an angle underwater to prevent air blockages.
3. Use clean vases and fresh water with flower food for maximum freshness.
4. Replace water every 2 days to prevent bacterial growth.
5. For drying, hang stems upside down in a dark, dry place for 2–3 weeks.

Planting Instructions

Ideal Planting Time

• Spring to early summer.

Location

Harvesting Tips

1. Harvest blooms when they are half-open for fresh use.
