reaches 4-5 feet high by 6-7 spread. A plant in my yard in 6 years went from a 24-30" plant to a 4-5 feet high by equal spread. It is starting to develope a slight pyramidal form. Reported to reach up to 25-30 feet tall.
Given to the Hew York Botanical gardens by RH Montgomery of Coscob, Connecticut prior to 1949.
This plant is purchased as small plants and they slowly out grow their intended space. They are truly a sleeping giant.
