Crinum ‘Stars and Stripes’ is a captivating ornamental plant known for its unique beauty and impressive presence in any garden. Its elegant form and striking blooms create an appealing focal point.
Distinctive Features of Crinum ‘Stars and Stripes’
Crinum ‘Stars and Stripes’ features striking, large, trumpet-shaped white blooms with vibrant red stripes. These flowers measure 5 to 6 inches long, named for their distinct, flag-like pattern. Individual blooms are fragrant and emerge in succession from mid-summer, continuing their display into late fall, with some reblooming.
The blossoms rise above a clump of narrow, pleated, glossy green leaves. It grows 2 to 3 feet tall and spreads 18 to 24 inches wide. New bulbs may take a season to establish before blooming, but their long-lasting flowers and robust foliage are reliable.
Ideal Growing Conditions
Crinum ‘Stars and Stripes’ thrives in full sun, at least six hours daily. In regions with intense summer heat, light afternoon shade can protect the plant. It adapts to various soil types, provided they offer good drainage, as waterlogging is detrimental.
Soil should be rich in organic matter (humus or compost) with a slightly acidic to neutral pH (6.0 to 7.0). Good drainage prevents bulb rot. Crinum ‘Stars and Stripes’ is hardy in USDA zones 8 to 10; winter protection can extend hardiness to zone 7 or 6.
Planting and Establishment
Plant Crinum ‘Stars and Stripes’ bulbs in spring or early summer, after frost danger and soil warming. Before planting, amend the soil with organic matter to enhance fertility and drainage. Crinum bulbs are large; ensure the planting location accommodates their mature size.
Dig a hole 4 to 6 inches deep, with the bulb’s neck just visible above ground. Space bulbs 12 to 24 inches apart for expansion. After placing the bulb, backfill the hole, firm the soil, and water thoroughly to settle it.
Routine Care and Maintenance
Once established, consistent watering is beneficial, especially during dry periods, though mature bulbs tolerate some dryness. Water deeply, allowing topsoil to dry slightly between waterings to prevent sogginess and bulb rot. Container-grown plants require more frequent watering.
Fertilization supports robust growth and prolific blooming. Apply a balanced, slow-release granular fertilizer in early spring, summer, and fall, working it into the soil. Alternatively, apply a half-strength liquid fertilizer monthly from spring through summer. Deadheading spent blooms can improve appearance and encourage further flowering.
Winterizing and Propagation
In colder climates outside USDA zones 8-10, winter protection is necessary. Where temperatures drop below freezing, lift bulbs in fall before the first hard frost. Dry them for a few days, then store in a cool, dark, dry place (e.g., in peat moss or shredded newspaper) with good air circulation. In marginally hardy zones, a thick layer of mulch (leaves or straw) over the crown can help bulbs overwinter in the ground.
Propagation occurs by dividing offsets (“pups”) that form around the mother bulb. Best done in late winter or early spring when dormant, this can be challenging due to bulb size. Carefully separate offsets with roots attached, and replant them at the appropriate depth and spacing. While Crinum can also be grown from seeds, division results in quicker flowering.
