Stewartia monadelpha

Tall stewartia is endemic to Japan and primarily grows in cool, montane temperate rainforest zones; specifically, south-central Honshu, Kyushu and Shikoku islands.[2][3] It is also cultivated in other countries as an ornamental plant.[3]

Its appearance varies from a sturdy shrub too a small tree with orange or cinnamon-brown colored bark.[4] It typically grows to a height of 20–25 ft (6.1–7.6 m) but has been known to reach 80 ft (24 m).[5] As the plant matures its form changes from a pyramidal crown to become more open with horizontal branches reaching outwards.[5] The dark green leaves are elliptic and oblong in shape and have serrated edges, growing to approximately 2–4 in (51–102 mm) long, and turn red in the autumn.[5] In June, small cupped flowers appear, growing 1–1.5 in (25–38 mm) wide the flowers are white with yellow stamens, similar in appearance to camellia flowers.[2]

This plant grows best in partial shade, but having an excellent heat tolerance, is able to grow well in full sunlight. In terms of soil, tall stewartia can tolerate well-drained clay, loam, sandy, and acidic soils.[2]
