Lemon Princess Spirea

Spiraea x bumalda 'Lemon Princess'

The Story

Plant Bio

Spiraea x bumalda is a hybrid group of compact, deciduous shrubs, resulting from a cross between S. japonica and S. albiflora. They are valued for their long bloom time and ease of care.

'Lemon Princess' is distinguished by its vibrant lemon-yellow new foliage that holds its color well through summer, contrasting beautifully with the clusters of pink flowers. It also offers attractive orange-red fall color.

Uses & Benefits:

Ornamental UsesThe primary appeal is the season-long bright yellow foliage, which acts as a constant spot of sunshine in the garden. The delicate pink flowers provide a lovely contrast in early summer, and the plant offers a final burst of coppery-orange fall color.
Practical UsesThis compact shrub is an excellent choice for filling gaps in borders, creating low-maintenance mass plantings, or defining a walkway with a low, informal hedge. Its toughness makes it suitable for a wide range of landscape situations.
Ecological BenefitsThe flat-topped flower clusters are easily accessible to a variety of pollinators, including bees and butterflies, making it a good addition to a pollinator-friendly garden.

Care Guide

Do

  • Provide full sun for the best foliage color.
  • Prune annually in late winter for best form and flowering.
  • Water regularly during its first season.
  • Deadhead after the main bloom for a tidier look.

Don't

  • Don't plant in waterlogged soil.
  • Avoid planting in deep shade, as foliage color will be poor.
  • Don't prune in late spring or summer, as you'll remove flower buds.
  • Don't over-fertilize, which can cause leggy growth.
