Ottawa Forsythia is a hardy flowering shrub, the first big splash of yellow before the leaves appear. Ottawa Forsythia flowers in spring in shades of yellow, and performs best in full sun with moderate watering once established. This shrub matures to roughly 5-9 feet tall and 5-9 feet wide. It is ideal for shrub borders, privacy plantings, and larger patio containers, offering seasonal colour and lasting structure. Once established it needs little attention, making Ottawa Forsythia a dependable choice for Canadian gardens. A layer of mulch helps hold moisture and keeps roots cool in summer.
