Establishment
3-6 monthsYoung plant or rooted cutting with minimal growth; stems are thin and upright or spreading
Keep in bright, indirect light and allow soil to dry between waterings. Do not fertilize during first year. Protect from cold temperatures below 50°F.
Vegetative Growth
1-2 yearsMature plant develops characteristic fleshy, 4-sided stems with a gray-green color and small tooth-like projections
Provide bright light, occasional watering, and minimal fertilization. Stems may reach 6-12 inches tall and produce side shoots.
Flowering
3-4 weeks per flower; blooming season is summer (June-August)Large, deep burgundy-brown star-shaped flowers emerge at the base or sides of stems, often with hairy, wrinkled petals and intricate patterns
Ensure plant is well-established (at least 2-3 years old) before expecting flowers. Provide bright light, cooler winter temperatures (50-60°F), and slightly more frequent watering during bloom season.
Post-Flowering
4-6 monthsFlowers fade and may develop seed pods; plant energy redirects to stem growth and vegetative expansion
Reduce watering as temperatures cool in fall. Allow plant to rest over winter with minimal water. Keep in cool conditions (50-60°F) to promote flowering the following year.
