Ironwood ' Golden Bell Tower ' Parrotia

Parrotia persica ‘Golden Bell Tower’ — Persian Ironwood

Most people notice flowers first in a garden. Ironwood earns attention another way — by foliage, structure, and autumn spectacle. ‘Golden Bell Tower’ is an upright, narrow selection of Persian Ironwood chosen specifically for smaller properties where a full-spreading shade tree would be too much of a good thing.

In spring, fresh leaves emerge soft green edged in bronze. Summer brings a dense, tidy canopy that casts light shade without heaviness. But the real performance arrives in autumn: gold, orange, scarlet, and burgundy often appearing on the same tree at the same time. Few trees match it for fall color reliability in warm climates.

Winter does not end the show. As the tree matures, the bark exfoliates into a patchwork of gray, tan, and olive — subtle but handsome, especially against low winter light.

Despite its refined appearance, Persian Ironwood is unusually tough. It tolerates heat, urban soils, humidity, and short dry spells once established. Deer typically leave it alone, insects rarely trouble it, and it asks very little pruning. In other words, it behaves like a tree used to surviving without gardeners.
