Autumn Wood is a favorite of mine - such a beautiful mix of colors. I'm in Zone 4b and it's not a big increaser here, but it blooms reliably and is always a bright spot in the garden when it does. I'm also including a picture of another, perhaps lesser known, intro by Dougherty in the same vein, called Golden Globe. I heard the hybridizer thought GG was even better than Autumn Wood - it's certainly beautiful and I'm glad to have both. I think I would also say GG increases and blooms a bit more vigorously here than AW. Very nice plants, both of them. (first pic is AW, second pic is GG)
