The above is the original cultivar that is generally a well-priced low spreading groundcover. The flowers close up at night, reopening when the light reappears in the morning.

We only occasionally stock the original variety, preferring to offer the newer versions from PGA. These have the same shaped flower but a slightly larger leaf and more variation in colour selection. The newer cultivars also seem to be denser and less "gappy" in growth habit.

'Purple Moon' and 'New Blue Moon' for instance are much deeper in colour -

What’s the go with convovulus cnorem, it’s more of a low shrub than ground cover like the ones you have pictured.
They tick all the boxes in the nursery with silver foliage but out of 10 you plant six will die off within the first couple of years. Not sure if that’s Adelaide soil specific.
