How to Grow Flowering Pear – Pyrus

Sharing is caring!

Ornamental flowering pears are grown for their profuse flowers that appear in late winter and early spring.

Pyrus are medium to large deciduous trees valued for their upright form. Most grow well in tight urban or street settings although some with closely angled branches can be susceptible to wind damage if not trained or pruned.

Pyrus are relatively fast-growing trees; they reach goo size in 10 years and full maturity in another ten. Flowers appear in spring before leaves unfurl. Leaves are glossy and green from late spring to late summer. In autumn, leaves turn yellow, orange, scarlet, and purple and hold on to the trees for several weeks.

Flowering pears can be used in lawns, large planting beds as specimens. They are well suited for patios, courtyards, entries, lining driveways, and street trees. Generally, their roots are well behaved and won’t buckle paving.
