The Metasequoia is part of the redwood family which are the tallest trees in the world. The metasequoia normally tops out at about 100 feet. It is a native to China and is unusual in being a conifer which is deciduous, losing its leaves after they turn bright bronze in the autumn.
It cones are tiny, only about one inch long, bloomy blue when young brown or dark brown when mature. Also, unkike many conifers, it isn't tolerant of frost and prefers a shelterted location like the Pleasaunce provides.
