    This stand of Umbrella pines in the Bronx Botanical garden was planted in 1908. It is called Tanyosho pine in Japanese.

    I've seen several specimens of this cultivar of the Japanese Red Pine, (a species that is similar to the Scots Pine of Europe and Siberia), : two old, large ones at arboretums over 60 years old, one maturing tree of maybe 30 to 40 years old in a yard, two smaller specimens about 8 to 10 feet high in well-to-do neighbourhoods, and I saw 2 or 3 plants sold from nurseries where I worked about 4 or 5 feet high. Like the mother species, the Tanyosho Pine has stiff needles about 3 to 5 inches long in bundles of 2. It often bears lots of oval cones about 1.5 to 2 inches long. I've never seen it self-sow, but any seedlings would not be like the cultivar. The foliage can become yellowish in winter. The Tanyosho cultivar is a compact form that slowly grows, about 6 to 8 inches/year, to 15 to 30 feet high. Its branches divide low near the trunk base and it forms a wide, umbrella-like crown. Its bark is orange and flaky over much of the branches and trunk. It is an expensive plant that some diverse or specialty nurseries sell. Being a Japanese Red Pine, there is a chance of the Pinewood Nematode spread by Sawyer Pine Bark Beetles finding and killing it; but being an infrequent plant in the east half side of the US, it mostly likely won't be found.
