Parrotia persica 'Vanessa' (Columnar Persian Ironwood)
Upright form of a tough small tree that requires almost no care in return for its year-round appeal. Patchy bark, spring bronze-green foliage, exceptional month-after-month autumn color, and attractive winter branch structure put it into a class that almost approaches the perfection of Paperbark Maple and Stewartia. What it lacks in flower appeal is balanced by its extreme drought tolerance and overall tough character.
Soft needles, pleasing form, and kind of pre-historic in its overall appearance, Umbrella Pine is somewhat slow-growing, but always in demand from those suppliers who invest in liners annually and hold them for 4-5 years. Best if not crowded or planted in a wet spot, or simply "let go". This is an expensive plant to buy but a profitable one to sell if you're patient and want to offer something other than red maples, crabapples and honeylocust.
