''Pyrus cordata'', the Plymouth pear, is a wild species of pear belonging to the Rosaceae family. It is a small tree, often found growing in hedgerows or at the edge of woods. The Plymouth pear is considered to be either a sub-species of ''Pyrus pyraster'' (European Wild Pear) or a distinct species. ==Description== ''Pyrus cordata'' is a deciduous shrub or small tree growing up to 10 meters in height. It is hardy to zone 8 and is not frost tender, but its ability to bear fruit and thus seed is dependent upon favorable weather conditions. It is in flower from Apr to May. The flowers are hermaphrodite and are pollinated by Insects. The trees have pale cream blossom with some pink. The smell of the blossom has however been described as a faint but disgusting smell compared to rotting scampi, soiled sheets or wet carpets. The odour attracts mainly flies including some more often drawn to decaying plant matter such as Bibio marci. ''Pyrus cordata'' prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil. It prefers acid, neutral and alkaline soils. It can grow in semi-shade (light woodland) but prefers full sun and often grows in hedgerows and at the edges of woodlands. It requires moist soil and can tolerate drought. It can also tolerate atmospheric pollution. It is common in Brittany, Northern Portugal and Galicia where it occurs at woodland margins on acid soils. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pyrus cordata」の詳細全文を読む スポンサード リンク
