Lynwood Gold Forsythia (Forsythia x intermedia 'Lynwood Gold') is a vigorous, deciduous shrub renowned for its early spring display of bright yellow, bell-shaped flowers that bloom profusely along its branches. It is a fast-growing, low-maintenance shrub, typically reaching 6–10 feet in height and width, making it ideal for hedges, screens, or specimen planting in USDA zones 5-8. 
Key Characteristics and Growth
Bloom Time: Early spring, often before leaves emerge.
Growth Rate: Rapidly grows 2–4 feet per year.
Size: Mature height is usually 6-10 feet with a 6-10 foot spread.
Foliage: Deep green summer foliage that may turn to a bronze-purple color in the fall.

Planting and Care Instructions
Sun Requirements: Full sun (6+ hours) is best for maximum blooms, though it tolerates partial shade.
