Identifying a Once-Blooming White Climber: Likely 'Frau Karl Druschki'

Clues from Your Description

A vigorous, once-blooming climber in Zone 7a (Alabama) with pure white, huge double tea-form flowers, pink-tinged buds, light green foliage, black spot susceptibility, and balling in low sun strongly matches 'Frau Karl Druschki' (Hybrid Perpetual, 1901).

Why ID Is Tricky

Over 300 new roses debut yearly; commercial lifespans average 5 years. Many old varieties look similar. 'Frau Karl Druschki' is a classic "white climber" often found in older gardens.

Verification

Compare photos at HelpMeFind Roses. If it matches, embrace its glorious spring show—just don't prune in spring (blooms on old wood). Prune only after flowering.
