Ussurian Pear (Siberian)
Lewis Mock Orange

Ussurian Pear is the most cold hardy of all pear species. It is frequently used as a rootstock or as a pollinizer for other pear varieties. The pinkish-white flowers that bloom in the spring and the striking fall colours make it well-suited as an ornamental addition to your landscape.

Ussurian Pear can also be used for forming hedges as it tends to branch quite low.

While the Ussurian Pear is considered self-pollinating, planting with another pear variety will increase yields. Can be paired with Krazulya Pear or Beedle Pear.

Lewis Mock Orange is a flowering ornamental shrub that produces an abundance of white, fragrant blooms. The flowers have a sweet scent similar to orange blossoms, with a hint of pineapple. They bloom for several weeks from late spring to early summer, attracting pollinators and other beneficial insects.

Native to North America, Lewis Mock Orange is found from the southernmost portions of Alberta and British Columbia, and south into the northwestern United States. It makes an attractive shrub and can be used in hedgerows, pollinator gardens, and naturalization projects. Blooms occur on the previous year’s wood, so it is recommended to prune after it has finished flowering.
