The flowers in today's photos are known as vinca. I set out a few years ago to look for a creeping plant to cover a fairly steep bank behind the lower pond, and had this in mind. I didn't think it would be hard to find, but the nurseries I went to didn't have it. I finally found 10 little plants at Walmart of all places - their total stock. I didn't think I had nearly enough, but I planted them and those 10 plants now cover the entire bank, and then some!
As a bonus, they're very early bloomers, and the plants were quite green already when the last of the snow disappeared. I was lucky to find 2 different colours and the bank is now covered with these pretty flowers.
