Montbretia

Also known as Crocosmia, this bold and beautiful perennial belongs to the iris family and grows in upright clumps with long arching flower spikes. Each stem bursts into vibrant red-orange blossoms that attract hummingbirds and pollinators all summer long. Montbretia is a striking addition to perennial beds and ornamental landscapes and thrives in a wide range of growing conditions. It readily naturalises in the garden and is easily divided once established.

Where Can You Grow Montbretia?

Montbretia grows best in Zones 5-9, preferring full sun and well-drained soil. It performs well in both garden beds and containers, especially in sheltered sunny spots.

History and Historical Uses

Native to southern Africa, Montbretia was brought to Europe in the 19th century and became popular for its vivid colour, unique form, and adaptability. It has long been cultivated as a garden ornamental and is valued for its visual impact and long vase life as a cut flower.
