Carnival is an attractive form of the Field Maple, featuring variegated leaves with cream-white margins and light pink growing tips. In spring, from a distance, you could almost mistake it for a white-blossom cherry tree, such as the extent of the white variegation.
In good conditions in the UK it will become a small tree of up to 5m - or a large bush in less favourable conditions - making it a good choice if you are looking for a Field Maple for a smaller garden. It is also suitable for planting in parks and community spaces.
This is also a good tree to plant if you want to help your local bees - the dull green / yellow flowers are not particularly attractive, but produce large quantities of nectar and are sought-after by bees.
