Candytuft

Here is a very nice short perennial.   Candytuft - Iberis sempervirions is a great border plant that only blooms in the Spring.  I used to not like it very much because of that.  But look at it in one of my clients' gardens in South Pasadena.  It has brighter whiter flowers than Alyssum, grows about 6 inches tall and stays to itself.  Pretty :-)
