All Dressed In White

May Tour 078

Many visitors have asked about the Snow-in-summer found in the Shade Garden and the Forget-Me-Not Pond.   It’s putting on quite the show right now – I encourage you to come out to see this pretty little groundcover, as well as the many other spring bloomers!

Snow-in-summer, Cerastium tomentosum, is an excellent flowering groundcover found in the Caryophyllaceae family (same as dianthus and carnations).  It is best grown in sunny, well-drained locations and will spread to fill in most areas quite nicely.  The silver-gray leaves will grow to about 6” and will form a dense mat of foliage.  In late spring to early summer, small white flowers will develop and reach to about 6-8”.

Snow-in-summer is relatively maintenance free, and rarely has disease or pest problems.  Root rot, however, is a possibility in constant wet conditions.   After several years, you might find dead patches but often the short-lived perennial reseeds and fills in the patches.

See you in the gardens.

  1. Hi, Mollie,

    Is this ground cover good around other plants? Say I have a little patch with a bush and some other flowers in it. Will Snow in Summer choke these out? Or can they co-exist?
