Griselinia Green Horizon 10 Litre Pot 110-120cm

Griselinia littoralis 'Green Horizon' – Broadleaf | Hardy Evergreen Shrub for Hedging & Screening Griselinia littoralis 'Green Horizon', commonly known as Broadleaf, is an outstanding improved selection of this classic New Zealand native, bred specifically for superior cold hardiness and even greater resilience in the UK climate. Combining the characteristic glossy apple-green foliage and dense, upright habit of the species with enhanced toughness, 'Green Horizon' is an excellent choice for evergreen hedging, privacy screening, and windbreaks in coastal, exposed, or inland garden settings. Its naturally neat growth and lustrous foliage give it a clean, architectural presence that works beautifully in both contemporary and traditional gardens. Habit & Appearance Foliage and form. 'Green Horizon' produces smooth, oval, leathery leaves in a fresh and vibrant apple-green, retaining their rich colour and gloss throughout every season. The habit is strongly upright and bushy, naturally building a dense canopy of well-furnished branches that makes it particularly effective as a privacy hedge or boundary screen. In spring, a flush of bright lime-green new growth adds a lively freshness to the plant, and in summer small, inconspicuous clusters of flowers may appear on established specimens, occasionally followed by tiny purple-black berries on female plants. As a fully evergreen shrub, 'Green Horizon' maintains its structure, colour, and screening value throughout the winter months when many other plants have lost their foliage entirely. Growing Conditions Position. Griselinia littoralis 'Green Horizon' thrives in full sun or partial shade and performs exceptionally well in exposed, coastal, or windswept sites where salt-laden winds and difficult conditions can defeat less robust shrubs. It tolerates urban pollution readily and is equally well suited to sheltered inland positions. As a specially selected variety for improved hardiness, 'Green Horizon' is more cold-tolerant than the straight species, though young plants in particularly cold inland areas will still benefit from a little frost protection during their first winter while they establish. Soil. Broadleaf is adaptable to a broad range of soil types, including chalk, sandy, and moderately heavy soils, provided drainage is reasonable. It performs best in a moist but well-drained, moderately fertile soil and, once established, develops a good degree of drought tolerance. Consistent watering during prolonged dry spells in the first growing season will help the plant settle quickly and build a strong root system. Care Pruning and maintenance. 'Green Horizon' is a low-maintenance shrub that requires very little attention once established. When grown as a formal hedge or screen, trim once or twice a year — ideally in late spring and again in late summer — to maintain a neat shape and encourage a dense, bushy habit. As an informal specimen or border shrub, only minimal pruning is required: remove any wayward or frost-damaged stems in spring to keep the plant looking its best. Like the species, 'Green Horizon' responds well to harder renovation pruning if an established plant needs reshaping or cutting back more substantially. Feeding and mulching. Apply a balanced, general-purpose fertiliser in spring to promote healthy new growth and maintain the vibrancy of the foliage. An annual mulch of well-rotted organic matter around the base of the plant helps to conserve soil moisture, suppress weeds, and gradually improve soil fertility. Griselinia littoralis 'Green Horizon' is generally resistant to common pests and diseases, making it a straightforward and rewarding choice for gardeners of all levels of experience. Garden Uses Versatile and stylish. 'Green Horizon' excels as an evergreen hedge, boundary screen, or coastal windbreak, and its naturally upright, well-furnished habit means it can also be used as a bold structural specimen in a mixed border. The clean apple-green foliage provides an elegant, neutral backdrop that flatters flowering shrubs and perennials of all colours. It pairs beautifully with other coastal-hardy plants such as Escallonia, Pittosporum, and Phormium, and combines well with ornamental grasses, Hydrangeas, and Hebes for year-round garden interest and texture.
