Which plant is also known as Montbretia?

Montbretia is the common name for Crocosmia, a genus of flowering plants in the iris family. This plant is particularly known for its vibrant, trumpet-shaped flowers that bloom in shades of red, orange, and yellow. Crocosmia is often used in garden landscapes for its striking appearance and ability to attract pollinators such as hummingbirds and butterflies.

Montbretia is typically associated with Crocosmia because the species Crocosmia x crocosmiflora was historically known by this name. The plant is hardy and can thrive in a variety of garden settings, making it a popular choice for both home gardeners and landscape professionals.

The other plants listed do not match this common name. Aquilegia, known as columbine, features different flower shapes and colors. Astilbe is recognized for its feathery, plume-like flowers and prefers shaded areas. Aster is a group of plants known for their daisy-like flowers, which bloom in late summer to fall. Therefore, Crocosmia stands out as the correct association with Montbretia due to its distinct flowering characteristics and historical nomenclature.
