Magnolia Vulcan

Transform your garden into a springtime showstopper with the breath-taking Magnolia 'Vulcan'. Renowned across Australia for producing some of the deepest, richest magenta-red blooms of any deciduous magnolia, this New Zealand-bred cultivar (M. liliiflora x M. campbellii) is the ultimate cool-to-temperate climate ornamental feature tree.

Before the vibrant green foliage emerges in spring, 'Vulcan' produces massive, upward-facing, ruby-to-port-wine cup-and-saucer blooms (reaching up to 20–25 cm across). Its upright, compact growth habit makes it just as suitable for suburban courtyards and formal driveway avenues as it is for expansive country acreage.

🧑🌾 Planting & Care Guide

• 📍 Positioning: Choose an open position with morning to midday sun, shielded from blustery westerly winds that can bruise the large petals.

• 🪱 Soil Preparation: Dig in generous amounts of aged cow manure, compost, and organic mulch. Magnolias prefer a slightly acidic pH (5.5–6.5).

• 💦 Watering Regimen: Water regularly during the first 1–2 growing seasons to establish deep roots. Mulch well around the drip line (avoid touching the trunk) to retain soil moisture through scorching Aussie summers.

• 🧪 Feeding: Apply a balanced, slow-release fertilizer suited for flowering shrubs and acid-loving plants in late winter and again in early summer.
