The Callery pear (Pyrus calleryana) is a deciduous tree native to China and Vietnam. It produces year long interest as it puts on a spectacular show in spring when it’s covered with clusters of white flowers. Then again in Autumn when temperatures cools, its leaves turn bright yellow, mahogany and red before dropping off for winter. These trees are not grown for their fruit, they do fruit but the fruit is small, hard and inedible.
There are a number of cultivars grown commercially but the thing that differentiates them is their shape. The cultivated varieties such as the Pyrus calleryana ‘Bradford’ or Pyrus calleryana ‘Capital’ are grafted and are grown to be true to type (exact clones). This means they are guaranteed to grow in the same shape and form as the parent plant.
The variety we propagate and sell here is the straight Pyrus calleryana. This is a seed grown variety and is the root stock on which the cultivated varieties are grafted onto. It’s chosen as root stock because it has vigorous roots which tolerate a wide range of soils. The only difference between these and the grafted cultivars is there may be slight differences in growth habit due to genetic variation of the seed. They flower them same, have the same tolerances and have great Autumn colours.
Unfortunately the grafted varieties have to be a certain size before they can be grafted and because we specialize in tube stock and young plants that are easily packed and shipped around the country, we’re unable to offer these varieties as a standard stock item.
