Establishment (Year 1)
3-4 months first seasonYoung vine with sparse foliage and limited growth; focus is on root development rather than flowering
Water regularly; mulch well; prune lightly to encourage branching; provide sturdy support structure; do not expect significant flowering
Vegetative Growth (Late Winter-Early Spring, Year 2+)
2-4 weeksNew shoots emerge from old wood; foliage develops with small leaves; vine begins climbing support structure
Prune in late winter to remove dead wood and shape plant; thin crowded stems; apply balanced fertilizer; install support if needed
Flowering (Spring)
4-6 weeks (April-May, depending on zone)Profusion of nodding, ruby-red bell-shaped flowers, 1.5-2 inches long, appear along the vine; delightful fragrance
Do not prune during flowering; deadhead spent flowers if desired to encourage tidiness; water consistently; avoid overhead watering to prevent disease
Seed Development & Summer Growth (Post-Flowering)
6-8 weeksFlowers fade; attractive feathery, silvery seed heads (achenes) form and persist; vine continues vegetative growth
Leave seed heads for ornamental interest; can deadhead for neater appearance; water during dry spells; apply balanced fertilizer in early summer
Dormancy (Fall-Winter)
4-5 monthsFoliage yellows and drops; vine becomes woody and bare; seed heads persist and eventually weather away
Minimal watering needed; no fertilizer; apply 2-3 inches of mulch for winter protection in colder zones; inspect for winter damage
