The older leaves are wider and the new growth is narrower. Often new leaves have a much different look than the more mature ones. Since this one is not listed in the Hosta Library or the Hostapedia it is difficult to tell the mature size of the leaves or the plant. Since it is a sport of a seedling of Justice it has the potential to be large.

This one keeps catching my eye on the hosta forum also. It's so cool!!

If you like it, get it soon. According to the Naylor Creek website, this one is likely to be available only this year, because it's the result of a failed attempt to tissue culture Justice. Not surprising, as Justice is known to be quite unstable. It's interesting that it's being listed as a medium, when, as peren.all points out, it has the potential to be quite large. I think it's going to be a very attractive plant at maturity, but then I like solid green hostas more than most people.

I saw this Justice about 7 years ago and it was 5 feet in diameter. I should have used something for scale because the leaves were HUUUGE which makes this pic misleading...

...and this was in May so not fully expanded yet.

Pity TC failed.

Agreed with others.....young leaves generally look different than mature.

tj, that is one humongous hosta!
