I have Love Pat and Silver Bay, and they don't look anything alike. Love Pat gets round, a bit cupped, and vase shaped, and is a darker blue. Silver Bay is a brighter blue, more of a mound, and has pointy leaves. Love both of them.

Looks like a nice haul. That's a big LS Shoremaster.

I posted a thread about going to Plant Delights open house and posted pics of various hostas in their display gardens. Nefertiti was one of them, if you want to see the pic. I bumped up the post for you. The pic doesn't do it justice, though, it was gorgeous! It was on my list as well and seeing the display just confirmed it. It came home with me, along with a few others as well.

I also got lakeside shoremaster, blue ivory and pewterware earlier in the season from them. They are all doing quite well. Their display gardens are extensive and I can see why most of the workers wouldn't be able to find a particular plant. They have A LOT of people working there. Probably only two or thre of them could have answered that for you. The more knowledgeable people were milling around in the display gardens when I was there this time, although that is not the typical that I see, but am sure they are around more often at the greenhouses. Anyway, I did see pewterware in the display gardens, but don't remember seeing the other two triplets.

I love Plant Delights and haven't found anyone that rivals the sizes that you can get of some of theirs at an open house. The staff is very knowledgeable and friendly, I find, about the specifics of each plant. Everyone's experiences are different, though. Hope you had fun there, anyway, and were able to mill around the display gardens a bit. They are quite impressive.
