Originating from Southern and Eastern Africa
- A low, spreading evergreen with dense, mid-green succulent leaves.
- Vivid yellow daisy-like flowers glow brilliantly from summer to autumn.
- Hardy and easy, it thrives in poor, well-drained soil in full sun.
A radiant gem, Delosperma congestum, the Cooper’s Iceplant, bursts with sunny charm. Its succulent, cushion-like foliage hugs the ground, lighting up low spaces. This tough beauty thrives in coastal beds, reaching 5cm tall and 30cm wide in 2-5 years.
Prized for its colour, it shines in intense sunlight for months. Its slender petals have white markings at their bases, where they surround a central cluster of golden stamens, adding to the radiant appearance of each flower. The brilliant yellow blooms scramble around taller plants, dazzling rockeries or pots. It loves Mediterranean or gravel gardens—perfect for Norfolk and Suffolk’s coastal plots.
Care Tips for Delosperma congestum, Coopers Ice Plant
- Soil & Sun: Needs poor, well-drained soil; full sun for best blooms, tolerates light shade
- Planting: Position it where no overhanging foliage competes for light. Exposure to wind is no problem; it hugs the ground tightly.
- Watering: Keep moist while establishing during dry conditions. Drought-tolerant once its roots have spread.
- Pruning: None needed—trim if it wanders too far
Bold and cheerful, Delosperma congestum brings vivid flair to East Anglia’s sunniest corners. Its cushion-like foliage makes it a low-care star for summer-long dazzle, softening gravel or slate mulches. Ideal for pots or rockeries, particularly where it can be viewed close-up.
Planting suggestions for Cooper’s Iceplant
Create a riot of colour in your garden, from the ground up! When the floral displays and bold foliage of Mediterranean plants are lit up from below, a truly spectacular ‘wall-to-wall’ composition of flowers is possible. Add Carpobrotus edulis and Lampranthus spectabilis orange-flowered to the mix. Add a dash of Lampranthus spectabilis ‘Tresco Red’ for extra heat, and set your garden ablaze for the summer.
Alternatively, its especially intense shade of yellow can complement other golden cultivars, rather than adding to a cacophony. Scrambling harmoniously around clumps of Hemerocallis ‘Bonanza’, Hemerocallis ‘Hyperion’, or Kniphofia ‘Wrexham Buttercup’, it underpins planting compositions.
