The Arnold Arboretum crabapple collection has long been recognized for its importance to the horticultural and scientific worlds. Because of the Arboretum’s many introductions and broad distribution of both cultivars and previously undiscovered Malus species from wild origin, it has been hailed as the “ ‘Mother Arboretum’ for flowering crabapples” (Fiala 1994). This collection remains popular with Arboretum visitors, especially during spring bloom and fall fruit display. Join the Arboretum on Sunday, October 19 from 1 – 3 in the crabapple collection on Peters Hill to enjoy a fall afternoon amid this historic collection. Activities will include a tour of the collection by our curatorial staff focusing on Arboretum-bred hybrid introductions, and information about pruning techniques and timing.
