Acer palmatum 'Red Dragon' (Red Dragon Japanese Maple)
Unlike most "red" selections that are in fact purple this is more true red. Its color remains vibrant throughout the summer. Smaller than most dissectums, with black bark and a slower growth habit, this maple is a good choice for bonsai or a container.
Acer palmatum 'Twombly's Red Sentinel' (Twombly's Red Sentinel Maple)
This Ken Twombly introduction has a unique narrow upright shape, attractive in many situations where space is limited, particularly close to a building or walkway. Plants in our landscape are more appealing with each passing season. It remains a strong maroon color all summer long here in NW Oregon.
