Forsythia x intermedia
Border Forsythia
Beloved for its prolific yellow flowers in very early spring, this mid-sized shrub is a hybrid of two Asian species.
It is tough and highly adaptable but has a tendency to sucker in the garden and even spread into natural areas.
Grows in sun or shade but best flowering occurs in full sun.
Tolerant of drought and urban conditions and deer resistant.
Because of its potential invasive qualities, consider planting a native alternative to forsythia.
