Mesa Verde Ice Plant, a cultivar of Delosperma, is a durable and visually appealing groundcover. This low-maintenance, drought-tolerant plant is an excellent choice for various landscape designs, particularly where water conservation is a consideration. Its vibrant blooms and spreading habit add color and texture to sunny garden spaces.
Understanding Mesa Verde Ice Plant
Mesa Verde Ice Plant (Delosperma ‘Kelaidis’) features radiant, daisy-like flowers, typically salmon-pink or coral with golden centers. This succulent forms a dense, low-growing mat, reaching two to three inches high and spreading up to 18-24 inches wide. Its fleshy, gray-green leaves resemble jellybeans and can develop a burgundy tint in cooler fall temperatures. ‘Mesa Verde’ is notably cold-hardy, thriving in a broad range of climates.
The common name “ice plant” comes from the unique, ice-like flakes on its succulent leaves. Native to South Africa, this perennial blooms prolifically from late spring through summer, often until the first frost, providing a long season of color.
Optimal Growing Conditions
Mesa Verde Ice Plant thrives in full sunlight, needing at least six hours of direct sun daily for optimal growth and flowering. Partial shade is tolerated, but insufficient light reduces bloom abundance.
Well-draining soil is crucial, as the plant is highly susceptible to root rot in waterlogged conditions. Sandy or gravelly soils are ideal, and it tolerates poor soil quality. A slightly acidic soil pH (5.5-6.5) is beneficial. For heavy clay soils, amend with coarse sand and gravel to improve drainage.
Once established, Mesa Verde Ice Plant is drought-tolerant and requires minimal watering. During the first growing season, water regularly to establish roots. Afterward, water deeply but infrequently, allowing the soil to dry completely between waterings to prevent rot. Overwatering is a common cause of decline for this plant, which prefers drier conditions.
This plant is well-suited for USDA Hardiness Zones 4 through 10, withstanding winter temperatures as low as -30°F (-34.4°C). In colder zones, a layer of mulch in late fall helps protect the plant through winter. Its ability to tolerate harsh winters and hot, dry conditions makes it a versatile choice for various landscapes.
Planting and Ongoing Care
When planting Mesa Verde Ice Plant, space plants 8 to 12 inches apart to create a continuous groundcover. Ensure excellent drainage before planting. In colder climates, plant by mid-summer for establishment before winter; fall planting suits warmer regions.
Ongoing care for Mesa Verde Ice Plant is minimal due to its inherent hardiness. Fertilizing is rarely necessary; a light fall feeding with organic fertilizer is sufficient if needed. Excessive fertilization can lead to winter damage. Light pruning maintains tidiness or controls spread, and winter-damaged stems can be removed in mid-spring.
This plant is highly valued for its versatility in the landscape. It serves as an excellent groundcover, forming a dense mat that suppresses weeds. It is suitable for rock gardens, xeriscaping, border edging, and erosion control on slopes due to its preference for dry, well-drained conditions.
Troubleshooting Common Issues
Most problems with Mesa Verde Ice Plant stem from improper moisture. Overwatering is common, causing mushy leaves or stem rot. If waterlogged, reduce watering and allow soil to dry between applications.
Poor drainage worsens overwatering, as standing water causes decline. Planting on a slope or in raised beds improves drainage. Amending heavy soils with grit or sand also creates a porous environment.
Insufficient sunlight hinders flowering, resulting in fewer or smaller blooms. While the plant grows, its vibrant display diminishes in shade. Full sun exposure maximizes blooming potential.
Mesa Verde Ice Plant is generally resistant to pests and diseases. However, consistently wet or shady conditions can increase susceptibility to fungal rots.
