Teresa,
Silverband (Variegata) has variegated leaves. I have purchased from Ensata Gardens, last year and this. They're real pros by all accounts and that's been my experience as well. Polly has a
Vendor List of top notch Iris growers as a sticky at the top of the forum.
Anyone who can grow Hosta like you do Paul is the one I'll put my money on. Just remember what Polly said about Miracide.
