This rare and beautiful variety of our native mountain mahogany offers larger, birch-like leaves with fuzzy and whitish undersides. The highly useful from generally reaches 8 – 15 ft. tall, but only spreads to about 6 ft. wide, making it ideal for narrow locations where a screening, evergreen, fast-growing bush is needed. Small, disk-like, creamy flowers appear in the spring, followed in summer by seed pods with hairy, grey tails which curl upwards, giving the plant a silver halo. Over time, the trunks are covered in a smooth, grey bark. The Island mountain mahogany typically grows much more rapidly than our local variety and is tolerant of moist or dry soils once established and part shade to full sun. Heat isn’t an issue. A great candidate for a container, where it is very amenable to pruning.
