Very showy flowers in the early spring. I use it to slightly drape over my wing walls. In good dirt mine are every bit of 3 feet tall and dense. The neutral comes from the fact that the branches will easily take root where they even come close to the ground. While not overly aggressive they do spread. Cutting the rooted branches back a couple of times per year takes care of this.
Had my forsythias for 4 years now. I have 8 plants in clusters around our patio, and they are beautiful in bloom, light green foliage in summer, and great yellow/purple/red fall color. Extremely hardy, and fantastic for smaller spaces as they grow to just about 3 ft height. Very low maintenance required, and thrive in my clay soil regardless of weather. My favorite forsythia.

I've grown this plant for about 5 years, through several years of drought, and one heavy, extended snowy period. It is tough as nails, stays knee high or lower, and blooms well. I have combined it with Phlox subulata 'Emerald Cushion Blue' in front, and Spirea prunifolia 'Plena' behind for an almost effortless beautiful combination that thrives and survives with little care.
