Whoa, I just stumbled upon doublefile viburnum at a local nursery and I'm totally hooked! Those horizontal branches with the double rows of white lacecap flowers look like something out of a fairy tale garden. Has anyone here grown this shrub successfully in zone 6? I'm dying to know the best spot for it-partial shade like they say, or can it handle a bit more sun? Also, do the red berries attract birds without becoming a mess? Planting my first one this weekend!
