Gardeners' Notes:

In cool-summer regions this plant needs the warmth and sun of a south-facing wall to do really well - it will produce masses of flowers up to 6cm. across all summer if happy.

In less ideal conditions the flowers will be smaller and fewer.

It's the most popular delosperma in the UK because of its hardiness and willingness to flower. In the UK I've known it to survive -8C (16F).

It's worth saving seed and sowing it because redder forms appear every now and then.

This has succeeded where other plants have failed in a very sunny, hot, dry spot in our garden. It receives a little incidental water when we water the grass - that's it. Not evergreen in our location, but has already started blooming in early May. It never gets tall - plant it at the front of the border.

In my experience, a very nice, long blooming plant great in rock gardens and even super sunny containers. We have terribly dry winters and often the foliage dies back but will return in the spring. If given some winter water, it'll remain evergreen.

Grows really fast. However, we bought this as a long blooming plant, but only had a handful of flowers on it last summer. So only giving it neutral.
