'Blue Mouse Ears' is a very good grower and will get a LOT larger than those pictured.
If you want solid colour, 'Baby Bunting' is a small blue that's a good grower. 'Tiny Tears' is a fast-growing green mini. Those are just off the top of my head. I'll post more later - all my pics are on my other computer.
As far as the "mice", I personally think they are highly overrated. Unstable with many variations which essentially fall into only a few categories - solid blue or green, white or creamy margin, white or creamy leaf centre and streaked. It's difficult to tell the difference between many of them, if indeed there is a difference. It's quite possible that multiple people experienced similar sports and that plants registered by more than one person may be virtually identical but under 2 different names.
But if you want a nice one, it's not part of the same family. I LOVE my 'Country Mouse'.
