Clematis has a shrubby side, where stems grow upright instead of twining and vining. ‘Stand By Me’ clematis features a shrub form that doesn’t need a trellis, although it may benefit from a little support. The blue blooms dangle like bells, opening from late spring through midsummer. Flowers fade to form fuzzy seedheads that are eye-catching and fun. Plants grow 34 to 38 inches tall by 24 to 28 inches wide. Cut stems back in early spring to 6 inches tall. Hardy in Zones 3-7.
