Crocosmia sp.

USDA Plant Hardiness Zone Map

Close

Crocosmia are a beautiful, long-lasting perennial that brings vibrant colors, and buzzing life to any garden. Crocosmia are deciduous, cormous perennials with erect, sword-shaped leaves and branched spikes of showy, funnel-shaped flowers in summer. Varieties produce blooms in a range of colors, including orange, yellow, red, crimson and vinous tones. Generally, these plants are resilient, thriving in full sun to semi-shade and tolerating a wide range of soils provided they are well-drained, with a preference for those containing loam, gravel and sand.

Crocosmia require moderate to regular watering, and benefit from fertilizer during the growth period in the spring and summer and a layer of mulch to protect corms in cooler periods. When planted in a warm, temperate climate, these hardy plants tolerate temperatures down to around 30 degrees Fahrenheit and usually bloom from October to May. However, if growing Crocosmia in colder climates, it is best to grow them in pots and bring indoors or cover during the winter, when temperatures dip into the low 20s Fahrenheit.

These vibrant plants not only restore color to gardens but also provide a home to butterflies, bees and hummingbirds. To further attract these species, ensure a sunny location and a reliable water source and adding a few mealworms.

Crocosmia can be grown in garden beds or pots; for colder regions, choose a container-grown plant and use a well-draining, sandy, loamy soil mixture. Additionally, provide plenty of sunshine, keep soil moist, and fertilize with general-purpose compost in the spring for vibrant, long-lasting blooms all season.
