Spring Glory Forsythia is completely covered in large bright yellow flowers in early spring. It is one of the great harbingers of spring, and reliably opens the gardening season each year. Spring Glory is an upright round shrub with slightly arching branches.
Forsythia Spring Glory is easily grown in loose, medium moisture, well-drained soils in full sun to part shade. Best flower production is in full sun. Tolerates average to poor garden soils. Moderate drought tolerance once established. Shrubs are vegetative winter hardy to USDA Zones 3-8, but may not always flower well in Zone 5 because of harsh winter temperatures or late winter freezes of unopened flowers. Flower buds are typically lost when winter temperatures fall below -5 degrees F. Development of unkempt growth often occurs if shrubs are not regularly pruned immediately after spring flowering (pruning done after mid-July will remove flower buds for the following spring). A wide range of pruning options exists for 6-10’ tall hybrids, one option being (a) an annual post-flowering removal of old wood combined with cosmetic shaping of the shrub, and (b) a major cut back of stems to almost ground level every 3-4 years for rejuvenation. Shrubs have good tolerance for urban conditions.
Forsythia is a genus of about 7 species of mainly deciduous shrubs from Eastern Asia with one species form Southeast Europe. They are great harbingers of spring with their early yellow flowers produced before the plants leaf out. Several hybrid selections have been made.
Genus name honors William Forsyth (1737-1804), Scottish superintendent of the Royal Gardens of Kensington Palace and author, among other works, of A Treatise on the Culture and Management of Fruit Trees which in its day was probably the most widely read work on the subject.
