Rowallane Yellow Montbretia

Crocosmia masoniorum 'Rowallane Yellow' displays graceful, arching stems adorned with golden-yellow, funnel-shaped blooms that brighten the garden from mid to late summer. Each vibrant flower opens sequentially along tall spikes, creating a layered effect that brings a lively energy to borders, where it pairs beautifully with other late-season bloomers.

Design tip

Late flowers extend the season, so set it behind or beside plants that finish in midsummer. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
