We saw this bush in the park, and my Seek app told me that it is Witch Alder.  Never heard of it, but it's so pretty, I thought we'd explore it together.    

 

My Wildflowers of North Carolina book says:
 

Fothergilla major or Witch Alder is a native colonial shrub.  It is a narrow endemic, meaning it naturally occurs in this area and not found anywhere else.  (How big "this area" is differs with each plant.)  Fothergilla major is found in the Piedmont and mountains of the Carolinas, Tennessee, Alabama, and Georgia, and is listed as threatened in North Carolina.  

 

North Carolina Gardener's Guide describes Fothergilla gardenii as a native deciduous ornamental boasting showy two-inch white "bottlebrush" flowers and dazzling fall colors.  It also suggests planting them alongside azaleas and rhododendron in a woodland garden, as they have similar growing conditions:  well-drained acid soils.  

 

Not sure if our local nurseries carry Fothergilla; but you may be able to find them in a nursery that specializes in native plants.  Or just go to Meeks Park this week and see one in bloom.  It's near the main entrance, as you start down the trail.

 

HAPPY GARDENING!!!
