A number of the trees that The Morton Arboretum's Head of Collections Kunso Kim and others have brought back from plant-collecting expeditions are planted on the Arboretum grounds.
Miaotai Miyabe's maple (Acer miyabei ssp. miaotaiense) is a rare Chinese tree whose native habitat is rapidly diminishing. It has been planted on the Arboretum’s East Side near the Buckeye Collection. It is closely related to the Miyabe maple, a native of Japan with corky-barked branches. The State Street™ Miyabe maple (Acer miyabei ‘Morton’), an excellent, tolerant shade tree for urban sites and a Chicagoland Grows selection, was derived from a tree at the Arboretum.
Sinowilsonia henryi is an unusual witch hazel relative native to the banks of mountain streams in China. It has been planted in the China Collection and the Witch Hazel Dell.
Lacebark pine (Pinus bungeana) is another rare and threatened Chinese tree. Its smooth gray bark is gradually shed in scales, revealing inner bark and giving it an intriguing lacelike appearance. It has been planted in the China Collection and the Conifer Collection.
The locations of these and every other tree in the Arboretum grounds can be pinpointed using the online plant database. Perhaps you’re thinking of planting a tree and you want to see how big the species is at maturity, or what it looks like in winter. Search the database by the botanical name to find whether the Arboretum has it and, if so, precisely where — complete with Google map.
