This is a beautiful white flower, especially in contrast to it's deep green foliage. It has a little more trouble in a colder climate, I think. Anything that can survive a winter like our last winter here is certainly hardy to zone 3b, but the plant is smaller and will take a couple season to completely recover itself. When it blooms, it's worth it.

In North Central Texas I have had 3 candytuft "Snowflake" for 3 years planted beneath a crape myrtle. It gets 3/4 day sun in the winter and it blooms profusely starting in early March.

It is planted behind veronica georgia blue which blooms at the same time and makes a beautiful white and blue carpet. I also have some yellow hoop petticoat narcissus within the planting that adds just a dash of yellow. Beautiful show. I prune it after the first flush of heavy blooms. I've heard candytuft is hard to grow in the harsh heat in Texas, but maybe the description of my conditions will encourage other Texans t... read more

A very nice looking plant year round. I takes the heat of summer well. I have a couple of varieties of this and am happy with both. My information says it is hardy in zones 3-10.

Iberis 'Snowflake' is beautiful in mid to late spring, blooming with the tulips. The evergreen foliage is attractive all year round. Shear the plants back by half after blooming to keep them compact. Or let them go to seed, then cut them back later in the summer.
