Crocosmia × crocosmiiflora (Montbretia): Vigorous Orange-Gold Perennial

Montbretia (Crocosmia × crocosmiiflora) is a vigorous, naturalizing hybrid that resembles a small gladiolus until late summer, when it erupts in abundant sprays of orange, gold, or yellow star-shaped flowers on gracefully arching, zigzag stems. Its pale green, sword-shaped leaves form attractive clumps. Excellent cut flowers, but be aware: it can be invasive in favorable conditions.

Growing Notes

• Site: Warm, south-facing location with good drainage; near a wall where not fully hardy.
• Winter: Thick mulch; lift and divide clumps in spring to maintain vigor and control spread.
• Propagation: Divide in spring.

Potential Issues

Spider mites; invasive tendency in some regions.
