Two in the medium range which are growing nicely for me are Paradise Island and Volcano Island, which is its sport. Paradise Island in May 2013 PI in July 2013 and in Oct 2013 While not of heavy substance, it seems that it has no troubles with slugs.... ....and then my Volcano Island which says "Large" on my tag, it is a tetraploid, and the dark green margins look hand painted, early in the season and later with the midleaf darkening in the last picture, note that Teatime is a really sweet medium that never seems to have a problem either. I'll work on uploading more Mediums.

I can raise the beds no more than 60 cm (2ft) on any side to be able to keep the beds a uniform height. This is because the window sill begins at 60cm from the ground along the house. I was coming to the same conclusion that you had just mentioned about the 3 ft not being large enough to accommodate a plant the size I would like so I have reworked the design a bit and got rid of the back portion that was 3ft wide and opted to plant in large planted atop an end table that is 4ft long by nearly 3ft wide which will allow me to create the height I want flanking the sofa. On 2 other end tables I will have smaller variety variegated hosta in planters. I've enclosed a screen shot of the new design idea

hey thunderbolt is an IMPROVED GE ... it will probably die.. but the peeps who have success tend to be up your way ... lots of bright light for this one... otherwise.. you have some old classics .. some new.. a nice selection .... but do understand.. size is more about leaf size.. rather than clump size ... the clump can get large.. and cover ground.. even on what you might call medium ones ... i have .. one of my favs.. a 15 year old clump of tiny tears.. that is about 8 inches round .. i wouldnt be surprised that there werent 50 crowns in there ..... you might put that in the mini category .... in fact a lot of what you have marked as large .. i would tend to call med-large .... like ERC .... i would move krossa regal more toward the large group.. rather than giant .... because of its vase shape ... since it holds it leaves upright.. it doest cover as much space as some giants who tend to umbrella them in a large circle .. ken

Empress Wu is marketed as the tallest hosta and not necessarily the biggest. Mr. Big can be huge but really needs a lot of water to do it. Sum and Substance clumps have been some of the widest recorded. And recently there have been quite a few hostas shown on the web even bigger than any of the records however those have been beefed up with tons of artificial fertilizers, so I'm not sure how that gets accounted for when taking size measurements... Most of the official sizes I've seen have been based on height but personally I think of them as a rough generalization without any exact measure - I just know when I see a huge hosta that it is huge or when I see a tiny hosta that it is tiny... And does anyone really care about the medium sized ones?
