Acer oliverianum

Acer oliverianum, the Oliver maple, carries the look of a Japanese maple on a tougher frame. Named for Daniel Oliver, the Victorian Kew botanist, this small Chinese and Taiwanese tree wears smooth jade green bark finely lined with white, and palmate, five-lobed leaves so like Acer palmatum that the two are easily confused. The difference shows in the constitution: the Oliver maple takes more heat and more drought than the Japanese maples, a welcome trait for warmer gardens that long for that filigree foliage.

New leaves open with a bronze cast, deepen to medium green through summer, and close the year in a superb mix of orange, red, and yellow that often holds late into fall. Small whitish flowers, set off by purplish sepals, appear in modest clusters and pass without fanfare before ripening to the winged samaras of the genus. The foliage has drawn comparison to sweetgum as much as to maple, a reminder that this is a tree of subtle, second-look beauty rather than instant flash.

Modestly scaled at roughly fifteen to twenty-five feet, the Oliver maple suits a sheltered border, a courtyard, or a woodland edge in zones 7 through 9, set where the jade bark and fine foliage reward a close look. Offer light shade in the hottest gardens and shelter from harsh, drying wind. Lovely among camellias, ferns, and other broadleaf evergreens that frame the airy canopy, this is a rare maple for the gardener who already knows the Japanese kinds and wants something quieter and more durable.
