Overview & Specifications
Italian Alder - Alnus cordata
Alnus cordata is a fast-growing deciduous tree delivering immediate structure, strong vertical presence, and reliable canopy at scale. At advanced sizes, it hits the ground running, establishing quickly where lesser stock would spend years catching up.
Why Italian Alder
Rapid establishment: One of the faster-growing deciduous species available, generating canopy and presence well ahead of comparable trees.
Glossy, refined foliage: Heart-shaped leaves with a clean, lustrous finish that reads well across large-scale landscapes.
Nitrogen-fixing root system: Actively improves soil biology over time, adding long-term value to the planting site.
Broad site tolerance: Performs across a wide range of soils including heavy, wet, and low-fertility conditions.
Strong upright architecture: Naturally columnar form suits formal and structured compositions without extensive training.
Ideal Applications
Avenue and boulevard planting: Uniform upright habit creates disciplined, high-impact corridors on residential and commercial properties.
Large-canopy shade: Fast coverage over entertaining areas, car parks, and open landscapes where results are needed without delay.
Windbreak and shelterbelt: A proven performer for rural and semi-rural projects requiring structural protection at scale.
Difficult or degraded sites: Soil-improving qualities make it a sound choice for remediation planting or challenging ground conditions.
