Acer cappadocicum 'Rubrum'

Rubrum Caucasian Maple, Coliseum Maple, Cappadocian Maple

synonym Acer colchicum 'Rubrum'

Description

Acer cappadocicum ‘Rubrum’ (Rubrum Caucasian Maple, synonym: Acer colchicum ‘Rubrum’) was marketed by Baumschule Booth in Germany in 1838. This cultivar was selected for its beautiful leaves that bud red-violet and its red hue that you can still see on the leaves that turn dark green in summer. As a standard or multi-stem tree, the Rubrum Caucasian Maple can reach a height of 15 metres, with a round to wide, egg-shaped, semi-open crown that is up to 9 metres wide. 

The Rubrum Caucasian Maple is a sight to behold with its decorative leaves that bud in tones of deep red and violet. In the summer, the leaves turn dark green with a red sheen, and its deep golden yellow autumn colours are truly phenomenal. The tree blooms in May with bright yellow standing corymbs. Acer cappadocicum ‘Rubrum’ produces a lot of nectar and pollen for bees. Young twigs are dark purple with white stripes; later on, they turn green. In its younger stages, the grey-brown bark has vertical stripes, and in older trees, the bark peels off. 

Acer cappadocicum ‘Rubrum’ is an elegant tree for avenues and as a solitary tree, it is perfect for parks and large gardens. The species can also be planted in wide streets if there is enough space in the planting area. Furthermore, with its dense branches, the selection is perfect for use as a shade tree. The Rubrum Caucasian Maple is not suitable for use in sealed pavement. The Rubrum cultivar can tolerate periods of draught, but the tree is not very wind-proof. Acer cappadocicum ‘Rubrum’ has quite a shallow root system, and the tree thrives in humous, moist environments in sun or partial shade.
