It is the standard white blossom stuff with a little yellow blossom clover mixed in to add hardiness and color. They put in a great root system so that it stays green even during those short periods when we go a week or more without rain.
If it’s like the clover that loves to invade my yard. If you don’t eradicate it before it flowers, then forget about going barefoot in the yard with all the burrs it puts out.
