Acer shirasawanum ‘Moonrise’
(Revised 23 Nov 2017)
This is a fairly new introduction. It appears to be similar to ‘Autumn Moon’. However, in contrast with ‘Autumn Moon’, it is reputed to have more red spring foliage and green foliage in summer, while ‘Autumn Moon’ retains its red tone in summer. The summer colour can be much paler in more sun.
Here is an extract from a UBC Botanical Garden Forum post:
“… Moonrise™ – ( syn. ‘Munn 001’) multi-trunked, low-branching tree, mature height probably about 18 ft (5.5 m) with a similar spread. New growth emerges carmine red, the leaves cup down, then open and spread out as they turn to yellow in sun, shade leaves are lime-green. In westerm Oregon it withstands full sun with very little leaf scorch. A chance seedling of A. s. ‘Aureum’ discovered by Carl Munn, in Brooks, Oregon, grows more vigorously than ‘Aureum’ (Plant Patent 16,718, June 26, 2006).
