An attractive lacecap hydrangea that produces light blue flowers in summer. Flowers can be more pink if the soil PH is more alkaline. 'Blue Billow' is a reliable bloomer! This particular hydrangea blooms on old wood. Prefers full sun to part shade, typically liking afternoon shade. Has a nice burgundy fall color.
