Ginkgo biloba 'Lemonlime Spire'

Lemonlime Spire Maidenhair Tree

Botanical Name: Ginkgo biloba 'Lemonlime Spire' PBR
Family: Ginkgoaceae
Origin: China (one of the oldest tree species on Earth; this cultivar selected in cultivation)
Plant Type: Deciduous tree

Overview

A living fossil with extraordinary seasonal colour in a refined, space-saving form, Ginkgo biloba 'Lemonlime Spire' is one of the most distinctive deciduous trees available for Adelaide gardens. Its striking fan-shaped leaves — delicately creased and unlike the foliage of almost any other tree — emerge in a vivid lime-green in spring, deepen to fresh mid-green through summer, and then turn a spectacular clear golden-yellow in autumn before the leaves drop cleanly together in one of nature's most satisfying seasonal displays.
A compact, fastigiate (strongly upright and columnar) male clone, 'Lemonlime Spire' produces no smelly fruit and holds its narrow spire shape naturally without pruning. It is exceptionally hardy, tolerating frost, heat, pollution and a wide range of soils, and its narrow profile makes it ideal for tight spaces, driveways, formal gardens and containers. Ginkgo is one of the most ancient trees on the planet — some specimens exceed 2,500 years of age — and this refined cultivar brings that extraordinary lineage to the modern Adelaide garden.

Key Features

• Mature Size: 5–6 m H x 1.0–1.5 m W (strongly upright, narrow columnar form; holds shape naturally)
• Growth Rate: Moderate; 20–40 cm per year
• Foliage: Distinctive fan-shaped leaves with delicately creased lobes; vivid lime-green in spring, deepening to fresh mid-green in summer; spectacular clear golden-yellow in autumn before a clean single leaf drop; deciduous; no leaves in winter revealing a refined architectural branch structure
• Flowers: Inconspicuous in spring; not ornamentally significant
• Fragrance: Not fragrant
• Seasonal Interest: Vivid lime-green new growth in spring; fresh green canopy in summer; spectacular golden-yellow autumn display; clean simultaneous leaf drop; refined bare branch silhouette in winter — a genuinely four-season tree
• Wildlife Value: Provides seasonal shelter and nesting habitat; spring and summer canopy supports insects and small birds
• Tolerance: Frost hardy (excellent); heat-tolerant; pollution-tolerant and well-suited to urban environments; drought-tolerant once established; wind-tolerant; adaptable to a wide range of soil types; male clone produces no smelly fruit; shelter from severe north-westerly sun and hot dry winds recommended in Adelaide
• Planting Density: Avenue/driveway: 1.5–2.0 m apart; deciduous screen: 1.5 m apart for a closely planted column hedge; specimen: 1.5–2.0 m from structures; suitable for large containers (50 cm+)
• Pet Friendly: Generally regarded as non-toxic to cats and dogs; male clone produces no fruit

Where It Works Best

• Sunlight: Full sun to part shade; best autumn colour and most compact habit in full sun; tolerates light shade; in Adelaide shelter from severe hot north-westerly summer winds will protect foliage quality
• Soil: Adaptable to most well-drained soils; tolerates sandy, loamy and clay soils; excellent urban and pollution tolerance; avoid waterlogging
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: low to moderate; deep soak every 10–14 days in summer; minimal watering in cooler months; drought-tolerant once established
• Maintenance: Very low maintenance; holds columnar shape naturally without pruning; remove dead or damaged branches in late winter if needed; apply slow-release fertiliser in spring if growth is slow; mulch annually; popular as a bonsai subject
• Lifespan: Exceptionally long-lived; Ginkgo is one of the world's most long-lived tree species; this cultivar will outlast most other trees in the garden
• Climate Zones: Well suited to Adelaide's temperate Mediterranean climate; performs best with cool to cold winters and warm summers; shelter from extreme north-westerly heat and drying winds in Adelaide's hottest conditions
• Soil pH: Adaptable; slightly acidic to neutral preferred; tolerates a broad range of Adelaide soil conditions

Landscape & Design Ideas

• Driveway and avenue planting in closely spaced columns for a formal, elegant approach that delivers brilliant green in summer and spectacular gold in autumn
• Narrow garden beds, tight side passages and small courtyard gardens where no other tree of similar visual impact would fit
• Formal garden vertical accent paired with clipped hedges, topiary and structured plantings for a sophisticated garden composition
• Container specimen for alfresco dining areas and courtyard gardens where the seasonal colour transitions create year-round interest in a manageable scale
• Contemporary and minimalist garden designs where the unique fan-shaped foliage and clean columnar silhouette create strong architectural impact throughout all four seasons

Why You Will Love It

'Lemonlime Spire' delivers four genuinely distinct seasons of interest in one of the narrowest tree footprints available — and it does it with the quiet authority of a species that has been growing on this planet for over 250 million years. The lime-green spring flush, the clean summer canopy, the brilliant golden autumn drop and the refined winter silhouette make this one of the most rewarding deciduous trees you can plant in an Adelaide garden.
