protea plant in pot Leucadendron galpinii 'Silver Cone': A Silver Sensation – Bonte Farm

🤍 Leucadendron galpinii ‘Silver Cone’
Silvery‑White Conebush with Sculptural Form

Leucadendron galpinii ‘Silver Cone’ is a refined evergreen shrub valued for its striking silvery foliage, architectural branching, and distinctive cone display. Unlike brightly colored Leucadendron cultivars, ‘Silver Cone’ offers a cool, elegant palette of pale grey‑green leaves that catch and reflect light beautifully throughout the year. Its prominent silvery cones add subtle texture and seasonal interest, creating a calm yet sculptural presence in the landscape.

Well suited to Leucadendron collections and contemporary garden designs, ‘Silver Cone’ thrives in full sun with excellent drainage and low water once established. Its clean form and neutral tones make it an ideal companion to bold foliage plants and flowering proteas, while its durability suits coastal, Mediterranean, and water‑wise landscapes.
