RECOMMENDED USDA GROWING ZONES: 5–9
1. Choose the right location
Choose a location with full sun to partial shade and well-drained soil. Lucifer Crocosmia flowers most heavily in sunny locations, although some afternoon shade can be beneficial in particularly hot climates.
Allow enough room for the plants to develop into substantial clumps. Mature Lucifer Crocosmia typically reaches approximately 3–4 feet tall, with upright, sword-like foliage and tall flowering stems.
2. Prepare the soil
Loosen the planting area and remove weeds, rocks, and debris. Crocosmia grows well in moderately fertile soil that retains some moisture while still draining freely.
Avoid locations that remain waterlogged, particularly during winter dormancy. Adding organic matter can help improve both moisture retention in sandy soil and structure in heavier soil.
3. Plant the corms
Plant Lucifer Crocosmia corms in spring after the danger of severe freezing has passed and the soil can be worked.
Plant the corms approximately 3–4 inches deep and 4–6 inches apart, with the slightly pointed end facing upward. If the growing point is difficult to identify, the corm can be planted on its side.
For the strongest garden display, plant several corms together in groups or drifts rather than scattering individual plants widely throughout the garden.
Water thoroughly after planting to settle the surrounding soil.
4. Water and care for your Crocosmia
Keep the soil moderately and consistently moist during active growth, particularly during dry summer weather. Do not allow the planting area to remain continually saturated.
Once established, Crocosmia is relatively easy to maintain. A layer of mulch can help conserve moisture during summer and provide additional winter protection in colder parts of its growing range.
Lucifer is a tall cultivar. Its stems are generally sturdy, but plants growing in exposed or windy locations may benefit from discreet support once the flower stalks become tall.
5. Enjoy the flowers and maintain established clumps
Lucifer Crocosmia produces arching stems of vivid scarlet-red flowers in mid to late summer. The tubular flowers open progressively along the stems above the plant's upright, sword-shaped foliage.
The flowers are attractive to hummingbirds, butterflies, and other pollinators and also make excellent cut flowers.
After flowering, spent flower stems can be removed for a tidier appearance. Leave the foliage in place while it remains green so the plant can continue storing energy in its corms. Once the foliage naturally yellows and dies back, it can be cut down.
Lucifer Crocosmia gradually multiplies underground and develops into larger clumps. If flowering begins to decline or the planting becomes crowded after several years, lift and divide the dormant clumps in spring and replant the healthiest corms.
In Zone 5 and colder exposed locations, apply a generous layer of mulch for winter protection. Where winters are too severe for the corms to remain reliably hardy, they can be lifted after the foliage dies back and stored in a cool, dry, frost-free location until spring.
Growing Lucifer Crocosmia in containers:
Choose a large container with excellent drainage and fill it with a well-drained potting mix. Plant the corms approximately 3–4 inches deep and position the container in full sun or partial shade.
Container-grown Crocosmia may require more frequent watering during active summer growth. Because containers provide less insulation than garden soil, protect the pot from prolonged hard freezes in colder climates.
