Delosperma Plug Plants: the “Ice Plant” Groundcover That Loves Sun
If you’ve got a sun‑baked border edge, a gravel patch that dries out fast, or a pot that always seems to need watering, Delosperma plug plants are one of the easiest upgrades you can make. Known as ice plants, these low, spreading, succulent perennials are built for bright light and lean soils—making them ideal for modern, low‑water gardens and classic rockery planting alike.

Why start with Delosperma plug plants?
Plug plants are a smart way to get strong, established young plants without paying for larger pots. With Delosperma, plugs let you:
- Plant in groups for faster groundcover (great along edging or on slopes)
- Fill gaps in gravel gardens and sunny raised beds
- Create a carpet of colour that’s tidy and low growing
- Save watering once established, thanks to their succulent leaves
If you’re already comfortable growing plug plants, Delosperma will feel refreshingly straightforward.

Where Delosperma grows best
Delosperma thrives when you match it with the right conditions:
Best conditions
- Full sun (the more light, the more flowers)
- Free‑draining soil (gritty, sandy, or improved with gravel)
- Raised beds, slopes, gravel gardens, pots (all excellent)
Avoid
- Heavy, waterlogged clay (especially in winter)
- Low, boggy spots where water sits after rain
Tip: If your soil is heavy, plant Delosperma on a slight mound or in a raised pocket with added grit.

How to plant Delosperma plugs
- Harden off plugs if they’ve been under cover (a few days of sheltered outdoor exposure).
- Prepare the area: mix in grit or fine gravel if drainage is slow.
- Spacing: plant plugs around 20–30cm apart for a filling, carpeting effect (closer for faster cover).
- Water in once, then water lightly during the first couple of weeks while they root in.

Watering & feeding
Delosperma is happiest when it’s not over‑pampered:
- Water: regular light watering at first; once established, only water during prolonged dry spells (especially in pots).
- Feed: a small amount of balanced feed in spring is plenty; too much nitrogen can reduce flowering.
Winter care in the UK: keeping Delosperma happy
Many Delosperma varieties are reliably hardy, but winter wet is the real enemy.
- Prioritise drainage (pots with grit, raised beds, gravel mulch)
- Avoid thick organic mulches that hold moisture around crowns
- In containers, use a gritty compost mix and raise pots slightly so water drains freely

Design ideas: where Delosperma really shines
Delosperma is one of those plants that looks “designed” even when you barely try. Great uses include:
- Border edging: crisp, low colour at the front of sunny borders
- Gravel gardens: pairs beautifully with silver foliage and drought‑tolerant perennials
- Rockery pockets: spill it between stones for a natural look
- Pots and troughs: ideal as a trailing “skirt” around upright plants
- Sunny slopes: helps knit soil and reduces bare patches
Companion plants
These are classic partners for Delosperma’s sun‑and‑drainage preferences:
- Sedum
- Sempervivum (houseleeks)
- Thyme (creeping thyme)
- Armeria (sea thrift)
- Campanula (for rock garden pockets)
Common issues
Not flowering well?
Usually needs more sun (or less feeding).
Going mushy in winter?
Almost always too wet—improve drainage, add grit, or move to a raised/gravel pocket.
Patchy growth?
Plant a little closer, and keep lightly watered until fully rooted in.
