I wonder what this is?

Hi Penny!

I wanted to ask what this plant is. It came in a seed packet for wildflowers but I don't think they are; they are lovely and have been blooming for several weeks now. They are also spreading, which I like! Thanks, Sherry

Hello Sherry... those are the lovely candytuft or Iberis. When they get tatty, just cut them back a couple inches and they will rebloom in about three weeks. At the end of the season, cut them back down to the ground.
