Outstanding Qualities

A unique selection of our native vine maple, Acer circinatum ‘Monroe’ has attractive, deeply divided leaves. It is well adapted to woodland situations but will tolerate a variety of conditions. Place it in a location where dappled light can play through its branches—its lacy, bright green leaves create a welcome contrast in shady evergreen woodlands. Cutleaf vine maple can be used as an elegant specimen tree combined with shade-loving perennials and small shrubs. It was discovered in Oregon by Portland resident Warner Monroe, brought into cultivation in 1965, and named by Brian Mulligan, former director of Washington Park Arboretum.

Culture Notes
This cutleaf form of our native vine maple thrives in open to deep shade. It is typically grafted onto Japanese maple rootstocks so it is not as drought tolerant as regular vine maples, requiring occasional watering during dry weather. It will grow well in a wide range of soils including sand and clay. It has a graceful wide open branching habit that requires little pruning other than the removal of poorly developed branches, dead wood or broken limbs.
Geek Notes
It was discovered at the headwaters of the McKenzie River in the Cascade Mountains of Oregon by Portland resident Warner Monroe, brought into cultivation in 1965, and named by Brian Mulligan, former director of Washington Park Arboretum, Seattle, Washington.
