Overview & Specifications
Alta Southern Magnolia - Magnolia grandiflora 'Alta'
A refined columnar evergreen delivering year-round structure and large, fragrant white blooms from late spring through summer. Magnolia grandiflora 'Alta' offers the full grandeur of a Southern Magnolia in a disciplined, narrow form, purpose-built for high-end landscapes where space and aesthetics are equally demanding.
Why Alta Southern Magnolia
Columnar Habit: Narrow, upright growth to 6–9m tall and just 2–3m wide, delivering height without sacrificing footprint.
Exceptional Flowering: Large, creamy-white blooms with intense fragrance from late spring through summer.
Evergreen Structure: Glossy, deep green foliage provides year-round presence and visual weight in any composition.
Climate Resilience: Established specimens are drought and heat tolerant, well suited to Australian conditions with minimal intervention.
Screening Density: Tight, dense canopy development makes it one of the more effective evergreen screening specimens available at advanced sizes.
Ideal Applications
Formal Screening: Planted in line, 'Alta' creates a tall, structured green barrier suited to boundary treatments on prestige properties.
Avenue Planting: Symmetrical rows along driveways or entry corridors deliver immediate formality and scale.
Architectural Feature Specimen: Used as a singular statement within a curated planting scheme or courtyard setting.
Constrained Urban Sites: The columnar form is well suited to narrow side passages, rooftop terraces, and high-density residential projects where canopy spread must be controlled.
