Bring early spring color to your landscape with Forsythia × 'Show Off®'. You will get a naturally tidy, upright shrub that is densely lined with bright yellow, bell-shaped flowers on bare stems in early spring, then finishes the season with clean green foliage that can show purple tones in fall.
Plan for a mature size of about 36-60 inches tall and roughly 60-72 inches wide. Give it room to arch slightly as it matures, and use it as a specimen, in mixed borders, or as a flowering hedge. It performs best in full sun for the heaviest bloom, but it also handles part shade well.
Plant in average garden soil with good drainage and water regularly the first season to establish roots. After that, it is adaptable and can handle short dry spells once established. A 2-3 inch mulch layer helps keep roots evenly moist and reduces summer stress.
Pruning is simple: because forsythia blooms on old wood, trim immediately after flowering if you need to shape it. Remove a few of the oldest stems at the base to refresh the plant over time, and avoid late-summer pruning that can remove next spring's flower buds.
