Growing Ocotillo in Cold Climates: A Kansas Experiment

Ocotillo (Fouquieria splendens) is a Chihuahuan Desert native—but with protection, it can survive Zone 6 winters.

Seed Germination

• Sow fresh seeds on surface of sandy mix; light required.
• Keep warm (80°F); germinates in 1–3 weeks.
• Seedlings need excellent drainage, full sun, minimal water.

Winter Survival Strategy

• Plant in protected microclimate: south-facing wall, gravel mulch, excellent drainage.
• Establish 1–2 years in pot; move to shelter (unheated garage) first winters.
• Mature plants in SW US survive 0°F if dry and established.

Other Out-of-Zone Successes

• Vitex agnus-castus (chaste tree): Dies back yearly, resprouts, blooms July.
• Magnolia grandiflora: Protected east wall in Kansas City, 20 ft tall for decades.
