Plectranthus argentatus: Velvety Silver Spurflower for Foliage Contrast

Silver Spurflower (Plectranthus argentatus) is an Australian native shrub grown primarily for its stunning velvety, silvery-gray succulent leaves. This fast-growing plant reaches 1–3 feet tall and wide, forming a spreading mound that adds instant elegance to containers, borders, and indoor displays. While it produces small white flowers in summer, the foliage is the star. Grow in dappled shade with moderately fertile, well-drained soil; indoors, provide bright light but shield from hot sun.

Growing Conditions

Keep soil evenly moist but well-drained; reduce watering in winter. Propagate by seed at 66–75°F, division in mid-to-late spring, or stem-tip cuttings anytime. Watch occasionally for mealybugs, spider mites, leaf spots, and root rot.
