Montbretia

Crocosmia

Also called Tritonia. These Iris relatives are corms, forming fast growing clumps composed of sword shaped, semi-evergreen leaves.
The funnel-shaped flowers, from 1 to 2 inches in length, are borne on arching spikes during mid summer. Crocosmias are great plants for attracting hummingbirds and butterflies. They make great cut flowers.
These perennials are easy to grow in full sun ( or partial shade ) on just about any light, humus-rich, fertile, well drained soil and are propagated from division during mid-autumn or early spring. Plants bloom best when divided every 2 to 3 years, they multiply rapidly with ideal conditions. Some species are so vigorous, that they may even become invasive in some places including New Zealand. The ideal planting depth for the bulbs is 4 inches.
Prune old and tattered leaves off during early spring.
Deep winter mulch or snow cover is essential during winter to protect the roots. Mulch heavily during the first winter.
Planting during late spring is recommended to give the plant time to establish before the following winter.
In zones 1 to 4; the fleshy roots can be lifted and wintered indoors in the same way as Cannas. The corms should be planted back out in the garden 6 inches deep on light,
fertile, well drained soil during spring after the last frost. In mild climates, the corms can also be planted during autumn.
Crocosmias are not eaten by deer and are not usually bothered by pests or disease either though spider mites may sometimes occur.
