Rose Flaming Peace

FLOWERING

Temperature swings exaggerate the contrast: cool nights deepen the crimson, while hot days lighten the reverse to pale cream. For gardeners who love the classic form of Hybrid Teas but crave modern fireworks, ‘Kronenbourg’ delivers: show-bench-sized blooms, a reliably repeat habit, and that unforgettable crimson-over-gold palette - all wrapped in the romantic pedigree of ’Peace’ / ‘Madame A. Meilland’.
