Gardeners' Notes:

A very hardy and reliable early season bloomer. Striking color combination. Easily divided after blooming to increase the size of the colony. Mine are thriving in half shade, getting some strong early morning sun. They are near some mature Spruces so it is not a very moist area. A memorable and generous gift from a fellow gardener.

This plant over-wintered great here in Geneva, Ohio. It is very cold and windy in my area and especially in my yard.
We had tons of snow and this came right back. It was one of the first things to look good and healthy. It bloomed a week ago and is growing each day. I bought 3 babies from Bluestone nursery, down the street and they are great. They are only 3 inches tall yet, but they haven't reached their height yet. The other species like this that I bought, (Cabrillo), is already 6 inches and growing daily, too. They are so cute. I love them.
