Description Of all the many different upright palmatum-type Japanese maple cultivars, ‘Bloodgood’ is considered the standard for which others are measured. In the landscape “Bloodgood’ leaves retain their deep red color all through the season if they are given partial shade.

This deciduous tree grows to a height and width of 20’ under ideal conditions. It bears 5-lobed leaves (with 2 small lobes at the base of the leaves) borne on red twigs, set in an opposite arrangement. Leaves range in length from 2” to 5”. The tree takes on a globose canopy at maturity. Branches assume a layered look over time, as this species develops multiple stems. Mature trees have muscular limbs which are considered picturesque during the dormant season. Fall color is considered excellent as the leaves turn a bright crimson color before being shed for the winter.

In April, reddish flowers form. By the late summer the flowers have morphed into red, 2-lobed samaras. The seed contained with-in the samara can germinate beneath the tree during the following spring.

As with other cultivars of Japanese maple, ‘Bloodgood’ prefers well drained acidic soils, on sites that receive good air circulation. If exposed to an excessive amount of sun during the day, the foliage can bronze out (sunburn) and develop a tattered appearance.

Verticillium wilt can be avoided by planting this species on a well-drained site.
