Quick Overview:

‘Suminagashi’ is a broad upright cultivar. Trees are vase-shaped when young, but gradually broaden with age. This is a fast-growing cultivar that typically grows to 8-10′ tall over the first ten years, eventually maturing to 10-15′ tall and as wide. Branches may weep at the ends. Palmate leaves (to 4″ long) are deeply cut into seven (less frequently 9) elongate-ovate lobes each having toothed margins and pointed tips. Foliage emerges purple red in spring, matures to deep maroon in summer and finally turns bright red in fall. Small reddish flowers in spring are somewhat attractive on close inspection, but are not showy from a distance.  (Courtesy of Missouri Botanical Gardens Plant Finder)

One of the best large-leaved red cultivars in the Matsumurae Group of Japanese maples.Easily grown in moist, organically rich, slightly acidic, well-drained soils in full sun to part shade. Grows well in sandy loams. May be grown in full sun in the northern parts of its growing range, but prefers some part afternoon shade in the southern parts of its growing range. New foliage may scorch in full sun locations in hot summers areas, particularly if soils are not kept consistently moist. Mulch helps retain soil moisture and keep roots cool. Avoid hot and dry sites. Site in locations protected from strong winds. Pruning is best kept to a minimum, but if needed should be done in late fall to mid winter.  (Courtesy of Missouri Botanical Gardens Plant Finder)
