Kilnashee's Snow-In-Summer
Cerastium tomentosum

My grandparents have snow-in-summer in their rock garden. I admired it one day, and they offered to give me some. I planted it at our old apartment, and despite the poor soil and lack of rain (because of an overhand), in flourished! Unfortunately when we moved, my husband turned in our keys before I had a chance to dig up my plants, so I lost it. I just bought some again this year, and I can’t wait to see how it does here.
