A great harbinger of spring, Forsythia ‘Happy Centennial’ is a compact, spreading, deciduous shrub with a profusion of bright-yellow, four-petaled flowers that appear before the leaves in early to mid-spring. The foliage of leathery, ovate, dark green leaves remains attractive throughout the growing season. Developed in Canada at the Ottawa Experiment Station, this Forsythia cultivar is recognized for its extreme flower bud hardiness (to approximately -30°F or -34°C). It will bloom heavily after even severe winters when many other Forsythia cultivars would not. Its low and horizontal branching makes it a very graceful shrub. Ideal for small gardens.
