1. About the Morrison Garden
(Transcription of the text in Photograph 3.) This garden is named in honor of the late Benjamin Y. Morrison, first director of the U.S. National Arboretum and originator of the Glenn Dale hybrid azaleas. Between 1940 to 1952, 445 cultivars of Glenn Dale azaleas were introduced.
The primary purpose in breeding the Glenn Dale azaleas was to obtain evergreen types with flowers as large and varied as those of the
Breeding of the Glenn Dales began in 1930 at the U.S. Plant Introduction Station, Glenn Dale, Maryland at the time Morrison was Chief, Division of Plant Exploration and Introduction and Acting Director of the U.S. National Arboretum. Several species and their varieties or cultivars were used in developing the Glenn Dale azaleas. These included Rhododendron kaempferi, R. mucronatum, R. indicurn, R. phoeniceum, and R. simsii.
As a result of this varied parentage, the Glenn Dales exhibit a wide range of flower size, form and color, blooming time, plant habit and hardiness. There are single, hose-in-hose, semi-double and double forms of flowers. Some cultivars have flowers up to 4¼ inches across. Flower colors are various shades of pink, rose, red, orange, purple, lavender and white, including some with stripes, flecks, variegated margins and throats. By selecting early, mid-season and late flowering Glenn Dales, bloom can be had in the garden from mid-April to mid-June. Plant habit
Dedicated May 3, 1954.
