  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Oct 24, 2020 7:57 AM concerning plant:
    This Japanese David Elm is native to Japan. I am not sure if they are including it into parts of the east Asian continent or not. Its leaves are large for an east Asian elm of being about 3 to 4 inches long by 1.5 to 2 inches wide, and it has 16 or less pairs of veins on the leaves. Selections of it that grew taller with an upright, arching form were used to bring forth hybrid elms that resemble the wonderful American Elm that was mostly lost by the Dutch Elm Disease. From the perhaps one out of a thousand American Elms that did have good resistance to the new Asian fungus disease, cultivars of the American Elm have been selected as 'Valley Forge' and 'Princeton' to be planted once again in landscapes. There also is work to bring forth natural trees that are not cultivars to restore the American species. The only Japanese Elms being grown in North America are cultivars, not the straight species.
