On Evey's site, there are a lot of Evison's cultivars that are shorter and good for containers but I noticed a lot of the other ones she carries are also shorter. Lots of yummy choices!

Not sure about the ones on your list, if they are not on Evey's site, this is most likely a good site that lists the heights,
