Ginkgo biloba 'Troll'
Origin and Habitat
Ginkgo biloba is a living fossil, native to China, where wild populations exist in remote valleys with moist, well-drained soils. It has been cultivated for thousands of years in temple gardens and urban landscapes across Asia. The cultivar 'Troll' originated in Europe as a dwarf selection, prized for its compact size and dense, rounded form. While it shares the ancient lineage of its species, 'Troll' was developed specifically for ornamental use in small gardens, patios, and containers, retaining the resilience and unique fan-shaped foliage of the species in a miniature form.
Description
Ginkgo biloba 'Troll' is a slow-growing, dwarf deciduous tree or shrub that typically reaches 20 to 24 inches in height and width. It forms a tight, rounded ball shape with short internodes and densely clustered branches. The foliage is composed of the classic ginkgo fan-shaped leaves, which are medium green during the growing season and turn a brilliant golden-yellow in autumn before dropping. While it rarely flowers or produces fruit in this compact form, 'Troll' offers seasonal interest and a sculptural presence year-round.
Cultivation
Zone USDA Zones 4–8
Temperature Tolerates a wide range from -30°C to 35°C, though prefers cool to moderate climates.
Growth Rate Very slow-growing; typically 1 to 2 inches per year.
Soil Requires well-drained soil with pumice for improved aeration. Tolerates various soil types if drainage is sufficient.
Watering Water deeply when the top inch of soil is dry. Allow soil to dry slightly between waterings. Avoid waterlogged conditions.
Fertilizing Feed with a balanced fertilizer every 2–3 weeks during the growing season (spring through early autumn).
Light Thrives in full sun to partial shade. Full sun enhances autumn leaf color.
Pests and Diseases Very resistant to pests and diseases. Occasionally susceptible to scale insects; treat with neem oil if needed.
Propagation
Propagated by grafting onto seedling Ginkgo biloba rootstock to maintain dwarf characteristics. Cuttings are rarely successful.
