Goza (Salix caprea 'Kilmarnock') – a deciduous ornamental tree, grafted on a trunk with a small weeping or umbrella-shaped crown, featuring branches that hang down to the ground. The height of the willow is usually 1.5–2 m, the width is similar, however, growth after grafting may be limited to just 20 cm, while branches rise upwards by 50 cm and immediately droop downwards. With regular pruning, the crown acquires a lush, umbrella-shaped form, making the tree especially attractive in small gardens, topiary ensembles, avenues, and as a solitaire near water bodies.
The leaves of Goza are weakly crinkled, elongated-elliptical, matte green with gray-hairy undersides. Autumn leaf coloration is bright yellow. Flowering occurs in March–April before leaf emergence: bare branches are covered with fluffy gray tufts («pussies»), which over time turn into golden-yellow catkins with a delicate aroma, creating an early spring effect.
The stems have dark reddish-brown bark, turning gray with age. The root system is superficial and tolerates heavy planting in the root zone well. The plant is undemanding but requires plenty of light and water; it prefers moderately moist sandy-clay soils from slightly acidic to slightly alkaline. Goza is resistant to air pollution, frost, and does not require winter protection. To maintain the umbrella-shaped form, spring pruning after flowering is recommended.
The cultivar was discovered in the UK in 1850 and received the Garden Merit (AGM) award from the Royal Horticultural Society, confirming its popularity and reliable ornamental qualities. Due to its compactness and bright spring flowering, the tree is ideal for greening gardens and parks, as well as as a potted plant on patios.
