Blue Shadow Fothergilla

Fothergilla gardenii 'Blue Shadow'

The Story

Plant Bio

Fothergilla gardenii, or Dwarf Fothergilla, is a small, slow-growing deciduous shrub native to the southeastern U.S. It is prized for its fragrant, bottlebrush-like spring flowers and brilliant fall color.

'Blue Shadow' is a sport of 'Blue Mist' with much more intense, powdery blue summer foliage that provides striking contrast in the garden. It also features the typical brilliant yellow, orange, and red fall color of the species.

Uses & Benefits:

Ornamental UsesOffers exceptional multi-season interest: fragrant white bottlebrush flowers in spring, stunning icy-blue foliage throughout summer, and a spectacular fall display of yellow, orange, and scarlet. Its rounded habit is neat and tidy.
Practical UsesIts compact size makes it a versatile choice for small gardens, foundation plantings, and mixed borders where it won't overwhelm other plants. It requires very little pruning to maintain its shape.
Ecological BenefitsThe honey-scented spring flowers are an excellent early food source for native bees and other pollinators. Its dense branching provides cover for small birds and wildlife.
