Gardeners' Notes:

The variegated leaves and lighter blue flowers on Emerald Mist are just stunning. This is an early bloomer in Minnesota and it is such a welcome sight in the spring. This is a solid performing perennial for any shade garden. The foliage remains very attractive all season. I suggest wearing gloves if you have to handle this plant; the leaves are rather thistle-like. Update spring 2012: love it even more. I've had difficulty finding this variety, and I'm frustrated because I want more of them.

I have 2 cultivars, 'Hadspen Creme' and 'Looking Glass' growing in 2 different spots in my garden. These plants have become a staple, as they are some of the first plants to come up in the spring, and they are some of the most beautiful! I love the dainty blue flowers, and the foliage is lovely. These are low-maintenance plants, and I have never had any pest or disease problems with them. I highly suggest them as a wonderful addition to any garden!
