Origin
IPP, Florence, Italy

San Zanobi is an elm cultivar raised by the Istituto per la Protezione delle Piante (IPP), Florence. Derived from a crossing of the Dutch hybrid Plantyn and the Siberian Elm Ulmus pumila clone N15, it was released for sale in 2003. It is a fastigiate tree, with a straight, long trunk and glabrous, bright green leaves up to 150 mm long, with a high resistance to Dutch Elm Disease. In Italy, San Zanobi begins flowering in its fifth year.

The tree was introduced to the UK by Butterfly Conservation in 2003, and is being evaluated at several sites in Hampshire. It has so far proven very fast growing on well-drained soil, increasing in height by over one metre per annum, but is intolerant of heavy ground waterlogged in winter.

[edit] Etymology

The hybrid is named after Saint Zenobius (San Zanobi in Italian), a saint noted for many miracles. After his death in AD 417, his body, whilst being carried from the cathedral for burial, is supposed to have glanced a dead elm, restoring the tree to life.
