How to grow trumpet vine

When to plant trumpet vine

Trumpet vine is a vigorous clinging native vine that blooms all summer (NC State: June to September) with red-orange trumpet flowers hummingbirds favor. Plant in spring on a sturdy structure; it blooms on new growth, so early-spring pruning will not affect flowering, and it suckers aggressively, so site it where you can mow runners back.

Trumpet Vine is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
