Bush to large tree, rarely medium-size. Somewhat resembles A. griseum at first sight, but differs from this in (among other things) its brown-grey, only slightly scaling bark. With A. griseum, the bark is reddish brown and profusely scaling. The leaves of A. triflorum are hairy and rather more blue-green on the underside. In summer they are green, but in autumn they turn a splendid orange to purplish red. The species name is derived from the fact that each flower corymb comprises only three flowers. A. triflorum should mainly be used as a solitary tree in a garden or park. It prefers a slightly acidic soil.
