Sienna Glenn Maple

Sienna Glenn tends to run more cold-hardy than other maple cultivars. At maturity it features a pyramidal form with nicely uniform branching, reaching around 55 feet tall and 35 feet wide with 2-3 feet of growth a year.

Showy red flowers line the branches each spring before the leaves appear, and the foliage turns a striking yellow, orange, and burgundy in fall. It’s an adaptable tree that tolerates moderately wet and dry conditions and shows good disease and mildew resistance, a reliable choice for its hardiness, adaptability, and low maintenance.
