  • Zone: 4
  • Plant Size: 2-3'
  • Bloom Color: Red
  • Habit: Mounded
  • Culture:

    Very adaptable. Full sun to light shade.

  • Notes:

    Similar to 'Anthony Waterer' but with deeper red flowers. Originated as a sport (a mutation at one point on a plant producing a branch that is different from the parent plant) on 'Anthony Waterer'. This is a sterile cultivar and can be safely used in areas where this species has shown the potential to become invasive.

  • Additional Information on S. japonica:

    Although this species has shown the ability to become an invasive weed in the Eastern U.S. and Europe, it has not yet escaped into natural areas in the upper Midwest. In areas where the naturalization of this species is a concern, there are three sterile cultivars that can be used without risk of escape: Crispa, Dart's Red and Neon Flash.

    Many of the cultivars recorded here are often erroneously listed under the synonym Spiraea x bumalda. Here all of these cultivars are correctly listed under S. japonica.

  • Pruning:Pruning animation

    Annually, cut the entire plant back 1/2 to 2/3's of the way. Following this remove any large, old canes as close to the ground as possible which will stimulate new sprouts to develop below the cuts.

    This type of pruning should be done when the plant is dormant, late fall to early spring.
