‘Northern Gold' Forsythia (Forsythia ‘Nothern Gold')
The arrival of brilliant yellow forsythia blooms are a true harbinger of spring. Now this yellow jubilation can be reliably enjoyed in northern gardens even as cold as Morden, Manitoba. ‘Northern Gold', developed from Forsythia ovata ‘Ottawa' and F. europaea parents by Felicitas Svejda of Agriculture and Agri-Food Canada, is one of the most bud-hardy cultivars available. Its golden yellow blooms cover arching branches in mid-spring (not just below the snow line, as is the case with some of its inferior cousins), shining like a beacon. This cultivar has a traditional upright vase shape (2 m high by 1.5 m wide) and blooms best in full sun. Plant this forsythia in moist, moderately fertile, well-drained soil. ‘Northern Gold' can look somewhat straggly as it ages (as do most forsythia), so keep its shape in check by pruning out up to one-third of the oldest branches after flowering. Plant in groups for added drama. Zone 3b.
