Black Gum
Ussurian Pear (Siberian)

Black Gum is a slow-growing ornamental shade tree with a dense pyramidal shape. The foliage is dark green in the summer, and transitions to bright fall colours which include red, orange, purple, and gold. It is commonly used as an ornamental tree in parks and large gardens as a specimen or shade tree.

The small greenish white flowers provide nectar for bees and black tupelo honey is a sought after flavour. The small dark blue fruits which ripen in late summer will attract birds and other animals to your yard. The fruits are edible, but very sour, and are primarily used for pies, flavouring, and drinks. Plant the Black Gum where it will live long-term, as it has a large taproot and does not transplant well.

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.
