How to Start It
★ Recommended for beginners
Roots very easily from cuttings — almost too easily, which hints at its vigour.
A rampant, tough climber with trumpet-shaped flowers that hummingbirds and bees adore. The warning: it's extremely vigorous and spreads by underground suckers — wonderful for quickly covering a big fence or pergola, but it can overwhelm small spaces and pop up in the lawn. Give it a strong support, full sun, and room, and be ready to cut it back hard each year.

How to Harvest
- 1Mostly your job is restraint: cut it back hard in late winter to a permanent framework (it flowers on new growth, so hard pruning means more flowers AND a contained plant), and remove unwanted suckers as they appear.
- 2Tie the main stems to a strong support while young.
- 3Once established it needs little water or feeding.
