Pear Tree (Pyrus)

Pyrus is a genus of deciduous trees and shrubs, not a single pear cultivar. Members have oval leaves and scented white spring flowers, followed by green or brown fruit; the fruit is edible in some species. A particular tree’s mature size, crop and pollination needs depend on its species, cultivar and rootstock. ## Choosing a pear tree For edible pears, select a named variety suited to the local climate and check whether it needs a compatible pollination partner. Rootstock strongly affects mature size: the [RHS pear-growing guide](https://www.rhs.org.uk/fruit/pears/grow-your-own) describes dwarfing and semi-vigorous options for different garden spaces. ## Growing conditions The [RHS Pyrus profile](https://www.rhs.org.uk/plants/88626/pyrus/details) describes the genus as deciduous, with oval leaves and scented white flowers in spring. A sunny, sheltered site helps fruit trees flower and set a crop. ## Maintenance Prune a pear according to its species, cultivar and training form. For fruiting pears, check the variety’s pollination requirements, thin heavy crops where appropriate, and harvest at the timing recommended for that cultivar. ## FireSmart BC source scope The chart lists pear (*Pyrus* spp.) as requiring more research on its appropriate placement zone. The chart's tree entry does not establish an individual assessment of every species or cultivar. Consult the [source chart](https://firesmartbc.ca/landscaping-hub/fire-resistant-plants/) and local guidance. ## New Zealand — FENZ Moderate/high flammability The [Fire and Emergency New Zealand directory](https://www.checkitsalright.nz/reduce-your-risk/low-flammability-plants) lists Pyrus sp. / Pear with Moderate/high flammability (main-directory entry 410). The scientific cell says Pyrus sp., indicating a pear whose species is not specified. This Pyrus genus record is only a qualified container for that unidentified source entry; it does not assign the band to every Pyrus species or cultivar. The directory separately lists unselected P. communis with High flammability, and that distinct species rating remains separate. No species or nursery clone is inferred from entry 410. The directory includes the full range of flammability bands; presence alone is not a planting recommendation. Higher bands mean more flammable and differ from Idaho's numerical resistance scale. Follow local guidance on plant suitability, spacing, watering, dead-material removal and management of higher-flammability plants. No plant is fireproof. Keep other regional source ratings separate.
