help - Blue Bird color,, but hardier
I was wondering if anyone out there grows a hardy outdoor hibiscus that has the same coloring and height as Hibiscus Syriacus Blue Bird, but is a zone or so hardier. I adore Blue Bird, but it seem to be just beyond the hardiness limit. I once had one grow for about 8 years, growing in a protected spot, but I guess we had a hard winter and it died.
I've heard of Blue Satin, but don't know if it really is hardier and if the color looks as purple-blue.
If there is such a hibiscus I'd really love to be able to send a SASE - Canadian friends would be easier for obvious reasons - and get some seeds.
