Bulletin of Popular Information, Series 4 Volume II number 3. May 14, 1934. Blanche Ames [Ames] (1878-1969) married Arnold Arboretum Supervisor Oakes Ames (1874-1950, and no relation) in 1900. was an American artist, political activist, inventor, writer, and prominent supporter of women’s suffrage and birth control. She often complemented her husband’s published works with illustrations, particularly of the orchid family. Their collaboration includes the seven-volume Orchidicae: Illustrations and Studies of the Family Orchidicae.

April is the perfect month to catch the bright flowering of Forsythia in our Living Collections. Spring is manifest in these golden, deciduous shrubs, and the Visual Archives at the Arnold Arboretum Horticultural Library curates brilliant Ektachrome color photographs of Forsythia, available online.

Forsythia is named after William Forsyth (1737–1804), the Scottish horticulturalist and a founding member of the Royal Horticultural Society.

According to British garden writer Stuart Phillips, Forsythia correlates in plant lore with “anticipation; good nature; innocence.” This link with the anticipation of spring makes perfect sense, and during your visits you can see a cluster of blooming where Bussey Hill Road intersects with Forest Hills Road, near the Bradley Rosaceous Collection.

In 1844, plant explorer Robert Fortune introduced Forsythia to western horticulture. Nautical transport during this era proved a challenge, as the specimens required sunlight and protection from salt water spray. Fortune used Wardian cases (solariums) to protect Forsythia during its long journey to Europe from the Orient by way of Cape Horn.

Forsythia has a long and storied history at Arnold Arboretum, starting with Ernest Henry Wilson’s 1918 introduction of F. ovata, from Korea, and the hybridization endeavors of Karl Sax during the 1930s and 1940s. It is native to Asia and AA cultivars within F. intermedia include ‘Beatrix Farrand,’ which Karl Sax named after the early 20th century landscape gardener (and this particular cultivar is a tall, sought-after landscape hybrid), ‘Arnold Giant,’ ‘Karl Sax,’ and ‘Primulina,’ a seedling that Arboretum research taxonomist Alfred Rehder (1863-1949) discovered by chance in 1912.

These flowering shrubs are also noteworthy for their hardiness in urban settings, superior by comparison with other plants more susceptible to disease. Their early spring bloom also helps distinguish them in the Arboretum landscape. During your visit, also remember to visit the library where we curate a wealth of information about Forsythia and other spring blooms.
