Establishment
2-4 weeksYoung plants are small and compact with thin stems and needle-like leaves starting to form
Water lightly and infrequently; avoid overwatering which causes rot. Ensure excellent drainage. Protect from heavy rain initially.
Vegetative Growth
4-8 weeksPlant spreads horizontally, developing more stems and foliage; dense mat of needle-like, gray-green to reddish leaves forms
Water sparingly; allow soil to dry completely between waterings. Apply balanced fertilizer diluted to half-strength if needed. No pruning required.
Flowering
6-12 weeks (summer through early fall)Abundant bright red-magenta daisy-like flowers (1-2 cm diameter) cover the plant; blooms open in sunny conditions
Continue minimal watering. Deadheading encourages more blooms but is not essential. Blooms close in shade or cool temperatures.
Dormancy
3-4 monthsPlant growth slows significantly in fall and winter; foliage may take on deeper reddish tones in cold; minimal flowering occurs
Reduce watering to minimal amounts; water only if soil is bone-dry. No fertilizing during dormancy. In zone 5, mulch lightly with sand or gravel (not organic matter) to protect from winter moisture.
Spring Renewal
2-4 weeksGrowth resumes as temperatures warm; new green foliage emerges and plant spreads further
Begin watering more regularly (but still sparingly) as growth resumes. Apply light compost or balanced fertilizer. Remove any dead winter foliage.

Common Pests
-
Remove with rubbing alcohol on a cotton swab; spray with insecticidal soap; improve air circulation to prevent infestations
-
Scrape off manually; apply horticultural oil spray; isolate severely infested plants
-
Increase humidity slightly and air circulation; spray with water to dislodge; use miticide if severe
-
This is primarily a cultural issue; ensure excellent drainage, reduce watering frequency, remove affected plants, repot in fresh dry soil if caught early
Uses
Edible Flowers & Ice Plant Leaves
CulinaryRed Iceplant flowers and foliage are edible and have a mild, slightly salty taste due to their succulent nature. The petals can garnish salads or desserts, adding color and a crunchy texture. Traditionally used as a novelty ingredient in gourmet cuisine. [source]

Harvest Tips
Delosperma cooperi is an ornamental and is harvested by cutting stems for flower arrangements or propagation. Harvest flowers in early morning when fully open for longest vase life. Stems can be propagated by cuttings taken in spring or summer; allow cuttings to air-dry for 1-2 days before inserting into well-draining propagation medium.
Fun Facts
- 🌱 The common name 'Iceplant' comes from the distinctive glistening, water-filled papillae (small hair-like structures) on the leaves and stems that catch light and resemble ice crystals or frost, giving the plant a sparkling appearance in sunlight.
- 🌱 Red Iceplant is native to South Africa and can survive extended periods without water by storing moisture in its succulent tissues, making it one of the most drought-tolerant flowering ground covers available for temperate gardens.
- 🌱 In colder zones (5-6), Red Iceplant is technically herbaceous perennial or semi-tender perennial, dying back to the ground in winter but reliably returning in spring; hardiness increases in zones 7 and warmer where it persists as a true evergreen.
