Fothergilla major (Fothergilla, Witch Adler, Mountain Witch Alder)


Michael's Opinion

An outstanding shrub that does not get the attention it deserves and would serve as an excellent border or screen in the landscape. The flowers are displayed as airy bubbles waiting to float away giving the shrub an enchanting feeling. The autumn colour is an added beauty dazzling the eye with hues of yellow, orange and red. Having minimal problems and easy to care for this shrub should be used in residential settings more frequently.

OriginA Scottish physician named Dr. Alexander Garden (1730-1791) who came to Charleston, South Carolina, USA and was a friend and correspondent of the Swedish botanist Carl Linnaeus (1707-1178) discovered several 'new' plants in the area. Initially one of these discoveries was named Anamelis since it was related to Hammamelis. However in correspondence with Linnaeus in 1774 the new genus of plant was named Fothergilla in honour of Dr. John Fothergill (1712-1780) an English physician who took part in many scientific discussions with Garden, Linnneaus and the prominent Philadelphia Quaker botanist John Bartram (1699-1777). F. major is generally found in the Piedmont plateau, from northern North Carolina and Tennessee to northern Alabama.
