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. When the crape myrtle leafs out it gets only dappled sun, but it has usually finished its major bloom by then, however I get sporadic light blooming during late spring and early fall. 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 to try it. It makes a beautiful early display.

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.
