Ice Plant

Delosperma spp.

Ice Plant is a low, mat-forming perennial succulent that brings daisy-like flowers over a broad, ground-hugging canopy from late spring into summer. At roughly 6 inches tall and 2 feet wide, it reads as a living carpet rather than a vertical feature. Use it where a sunny planting needs a low layer that will not block views, cover the base of taller plants, or overwhelm a narrow bed edge.

Placement and use

Place Ice Plant at the front of sunny borders, along the top or face of a dry slope, or through rock-garden pockets where its spreading stems can knit open ground together. Keep it outside the main line of travel: its low mat is better treated as a planting surface than as a walkable path. On slopes and banks, arrange plants in staggered rows so their mature spread can cover the grade without creating a rigid grid.[1][3]

Spacing and mature footprint

Set plants 18 inches apart, center to center, for a continuous groundcover planting. Each plant can ultimately spread about 2 feet wide, so neighboring mats may meet and overlap slightly as they fill in. In a mixed bed, reserve a 2-foot-wide zone for each plant and keep taller or more upright neighbors behind it, rather than placing them through the middle of its intended carpet.

Three plants set 1.5 ft apart, center to center; shaded circles show the 2 ft mature spread.

Sun, water, and soil

Give this groundcover full sun and use it in a low-water part of the plan. It suits sharply drained soil, including sandy, gravelly, or shallow rocky areas, where water does not linger around the crown. Avoid placing it at the bottom of a bed, beneath a downspout, or beside plants that need regular irrigation; those positions work against the dry, free-draining conditions it needs.[1][2]

Seasonal notes

Flowers occupy the mat from late spring into summer, adding color without changing the plant's low profile. Leave enough open space around the planting edge for the bloom display to remain visible rather than being shaded or covered by taller seasonal growth. The persistent groundcover footprint makes it useful for holding a bed's front edge between flowering periods.

Planning caveats

Winter performance can be less dependable where plants sit wet or remain under prolonged snow cover. Build drainage into the site before planting, especially in heavy soil, and favor a raised pocket, rocky slope, or bed edge that sheds water. Do not use Ice Plant to bridge a route through the garden; provide a path or stepping surface beside the planting instead.[2][3]
