Dormancy
3-4 monthsBulb is resting; foliage may be minimal or absent.
Provide cool, dry conditions during winter rest period (typically November-February in Northern Hemisphere). Minimal watering required.
Emergence & Foliage Growth
4-6 weeksGrass-like green leaves emerge from the bulb as temperatures warm; roots establish.
Resume watering gradually as growth begins. Ensure excellent drainage. Begin light feeding with dilute fertilizer.
Budding & Flowering
6-10 weeksThin flower stems emerge bearing trumpet-shaped buds that open into pink or red blooms.
Maintain consistent moisture but avoid waterlogging. Support tall stems if needed. Deadhead spent flowers to encourage more blooms. Feed with phosphorus-rich fertilizer.
Post-Bloom & Senescence
4-6 weeksFlowers fade; foliage may begin to yellow as the plant prepares for dormancy.
Allow foliage to mature fully to replenish bulb reserves. Continue light watering. Cease fertilizing.

Fun Facts
- 🌱 Habranthus bagnoldii is sometimes called the 'Rain Lily' because it often produces a spectacular flush of flowers after warm summer rains, a trait that helps it thrive in its native South American habitat with distinct wet and dry seasons.
- 🌱 Unlike many bulbs, Habranthus prefers frequent division and grows best when bulbs are somewhat crowded, producing more blooms in a dense planting.
- 🌱 The genus Habranthus belongs to the Amaryllidaceae family, which includes popular ornamentals like amaryllis, hippeastrum, and daffodils, yet remains relatively uncommon in cultivation outside of specialist bulb collections.
