RM Tarnished

RM Tarnished is a richly nuanced introduction from River Merle Farm, celebrated for its evolving terracotta and rust-toned blooms. The 4-inch flowers blend warm clay, muted copper, and antique rose hues with subtle tonal shifts that deepen as the season progresses. Early blooms may display green centres that gradually close as they mature, particularly in northern climates.

One of the defining traits of RM Tarnished is its colour variability. Light levels and day length influence how the tones present in early August the blooms may read warmer and brighter, while September flowers often deepen into more muted, antique shades. This dynamic quality gives the variety its namesake ’tarnished’ character and makes it especially valued in wedding and romantic floral palettes.

Plants grow to approximately 3-4 feet in height and produce steady flushes of blooms on usable stems throughout the season. The balanced plant habit and reliable performance make RM Tarnished both a designer favourite and a practical addition to cutting gardens. It is also known to be an excellent tuber producer.
