Reviving a Neglected Devil's Backbone (Pedilanthus tithymaloides)

Fifteen months in a dark room without water—and it's still alive. That's the remarkable resilience of Pedilanthus tithymaloides (Devil's backbone, zigzag plant). Here's a step-by-step recovery plan.

Immediate Steps

1. Move to the brightest window. Full sun is ideal; this plant thrives on light.
2. Prune strategically. Cut the two tallest canes back by half, even if leafless. Wear gloves—the milky sap is a skin irritant and contains latex-like hydrocarbons (researched as a potential biofuel source).
3. Fertilize lightly. One application of half-strength houseplant fertilizer now.
4. Water sparingly. Every two weeks until late April; let soil dry between waterings.

Spring Transition (Nights >50°F)

• Move outdoors to dappled shade or a shaded porch.
• Prune entire plant back to ~12 inches.
• Fertilize again in June.
• By September, expect a bushy, well-branched plant ready to come indoors for winter.

Long-Term Care

• Bright light year-round.
• Well-draining cactus/succulent mix.
• Monthly fertilizer during active growth.
• Protect from frost.

This plant wants to live. Give it light and patience, and it will reward you with its distinctive zigzag stems and colorful bracts.
