I remember someone here ID'ing this for me a while ago and I generally tag pages with an ID but all my tagged pages seem to have disappeared. This plant has a distinct blue cast and it stays low, this one is less than 10" tall. The leaves are about 5".
BegoniaDude, Can you provide some pictures of D.M. and Frosty and the differences? They look very much the same by the pictures on the web. I was thinking Don Miller has a bit more green in the leaves compared to Frosty or the other way around.
Here is one I bought as Don Miller years ago (R.I.P.) The mallet class is so hard to keep through winter due to being mildew magnets.
