Any of the white edged Sum and Substance sports.

I believe that the largest white edged green hosta that is widely available is Victory. There are some larger ones, but they aren't in production, as I understand it.

To illustrate that, I have Winter Snow, a sport of S & S, with a fairly narrow white margin and a light green or chartreuse leaf. This is what it looks like in its second year:

A question though:
How white do you require? I think Sagae has a creamy border and it is a fantastic big guy, but whether you think it is a light enough margin is up to you to say. Look for it because I do not have a Sagae--yet. :)

I have Victory in 3 pots now, wish I'd planted them all in one. A really smooth plant in its first year with me.
Here is the 2-eye pot:

and one of the 1-eye pots with a medium-sized quick growing fragrant Iron Gate Delight (white margins) in the background.

I recently won this plant on HL Auction from the breeder, Stuart Asch, and it might wind up being a big dude. Sure is looking fine: Nathan's Nirvana

It also depends on your idea of big. Frosted Jade makes a nice large leaf with a rippled edge.

It's probably Victory. It emerges yellow and then goes to cream and then white. The pic below was taken at the end of June.

Well antioch is a pretty big showy white edged hosta for me....but looking at pictures it's not as white as mine.

Any large ones that emerge white, not cream or yellow?

I have a green/white section, and I think the creams clash with the whites. (Even though the creams eventually turn white)

Parhelion may not be the biggest but it is big. Mine is pictured two years in my Theresa's Angel Garden under a black walnut tree. This progeny of S&S is growing like crazy. That is a mature silver maple treein front of it.

psst: that's a lie, it is just a seedling. See the 6" ruler?

Gee, Les, Parhelion looks a lot like Winter Snow, another S&S progeny. They both have a very fresh look to them. I'll concede that Parhelion is much bigger than the Winter Snow I have.

Time will tell. "My Hosta Base" in HL has Winter Snow rated as VL and Parheliion as L. Regardless, they both are a striking light green with white margins and good substance. I like them better than my S&S.
I was down on G/W variegated hostas for a while, but within the past year have added Dianna Remembered, Liberty, El Nino and Sweet Innocence, and would like Victory. My 3 year old Fragrant Bouquet is stepping out and developing wider white margins this year and Regal Splender shows promiss. But if any of these get really large it will be a surprise.

Les

My Parhelion is the largest green and white I have. My Sagae is bigger,but the edges stay yellow-to cream,not white. Excuse the hail holes,please. Phil

Spartan Glory is a nice fast growing large one, I also like His Honor. Many of the Sum and Substance sports are nice but also not that different from one another. Rob
