Why Climbing 'Peace' Roses Refuse to Bloom: The 5-Year Wait and Better Alternatives

Climbing Peace is notorious for 5–6 years of cane-building before first real bloom. Even then, only one small flush per year. Your raised planter isn't the problem—the variety is.

Recommendation

Replace with a climber that flowers generously: Zephirine Drouhin, New Dawn, Dublin Bay, Aloha, Westerland. You'll get flowers this decade.
