'Blue Mouse Ears' is my favourite of its large family. I've found that too many of the sports look alike or nearly alike and too many of them are unstable. Most of the ones I've had with white or light leaf centres have reverted to solid blue. BME seems the fastest growing and the most stable of the family.
This picture is from early July. I missed most of the bloom by being away for two weeks in July. You see around it, a few other of the BME family. To the right, a slow growing 'Royal Mouse Ears', behind it there are 'Frosted Mouse Ears' and 'Mighty Mouse'. To the left you see a bit of a 'Snow Mouse' which has reverted to solid blue, but seems slower growing than BME. And in front, you see a bit of 'Pure Heart' which has, so far, done well.
Please feel free to post your own pictures of this hosta.
