Trumpet Vine Propagation: Seeds vs. Layering for Las Vegas

Campsis radicans: Easier Vegetative Methods Than Seeds

Trumpet vine seed pods (string bean-like) contain viable seeds but require 60-90 day cold stratification.

Seed Method

1. Seeds in damp towel, bag, refrigerate 60-90 days
2. Pot up, 70-75°F, germinate in weeks
3. Harden off 10 days post-frost
4. Full sun

Better: Layering or Suckers

• Dig suckers from base of mother plant
• OR: wound low branch, peg to soil, weight with rock
• Roots in 2 months
• Sever and transplant

Las Vegas Timing

Don't start seeds now (late summer)—winter kill risk. Start January indoors. Layering can begin now in warm climate.
