Hello. I recently bought 2 quart-size containers of delosperma (ice plant) to start a ground cover. It has tiny white flowers that look like miniature daisies. 1) Is this plant evergreen and 2)can I divide the plants from the containers into several plants each? I haven't found exactly what I need when I researched it on the internet. Thanks so much for any information anyone can give. To all who read this, have a wonderful week.
