Native to Japan, Korea, eastern Russia, and Mongolia
Ken Twombly in the late 1970s saw a large specimen of the "Bloodgood" Japanese Maple variety while visiting a church in eastern Connecticut — took it to his nursery nearby
What differentiated this tree was an unusual clump of compact, upright branches
After being cultivated, their upright form was so dramatic that they resembled red sentinels on guard, hence the name
To this day, it's the only columnar Japanese Maple out there
