A well known medium-sized tree that flowers very early in spring and has bright autumn leaf colour that is held well on the branches. Pyrus ussuriensis is suitable for many landscapes, including parks and large gardens.
Habit: Dense, rounded. Pyramidal when young.
Foliage: Glossy, dark green rounded leaves turning to varying autumn tones of plum-red, scarlet and gold. Foliage is held on the tree well into late autumn.
Flowers: White flowers to 3 cm across in early spring are pale pink in bud. One of the first ornamental pears to flower in spring.
Fruit: Edible, greenish-yellow, globose pomes up to 3 cm in diameter.
Bark: The young branches are purplish-brown.
Tolerances: Adaptable to a variety of conditions including moderate drought, air pollution and exposure. May struggle in very warm regions and in compacted soils.
Is steadily being superseded by new introductions of ornamental pear that are superior in growth habit, structural stability and form. Best in full sun. (source: flemings.com.au)

|Germination||1. Fill a plastic bag with moist peat moss. Bury the pear seeds 2 to 3 inches in the peat moss and close the bag. Place the plastic bag in the bottom crisper drawer of the refrigerator for up to three months, or until the last frost date has passed. Ensure that the peat moss stays damp but not soggy the entire time it is stored in the refrigerator.|
2. Remove the seeds from the refrigerator and plastic bag when outdoor temperatures remain steady above 40 degrees Fahrenheit. Soak the seeds in a bowl of warm water for two days to help soften the hard outer shell of the pear seeds.
3. Place biodegradable peat pots on top of a plastic water tray. Fill the peat pots 3/4 full with organic potting soil. Remove the pear seeds from the bowl of water and lay one pear seed on top of the potting soil in each peat pot. Cover the pear seeds with a 1/2-inch layer of potting soil.
4. Water the pear seeds until the soil is moist. Cover the peat pots loosely with plastic wrap to raise the humidity. Set the plastic tray and peat pots indoors in a warm location that receives plenty of indirect light. Keep the soil moist until the pear seeds germinate. The rate of germination will depend on which variety of pear seed you have.
5. Remove the plastic wrap when the pear seeds have sprouted above the soil line in each peat pot. Move the water tray and peat pots to an indoor location that receives brighter light, such as a windowsill. Continue keeping the soil moist for several months, or through the winter months.
6. Feed the growing pear seedlings a liquid houseplant fertilizer as directed on the package label.
7. Plant the pear seedlings in well-draining soil, in a location that receives full sunlight when the threat of frost has passed. Break up the soil in a planting area twice the size of the peat pot the pear tree is growing in and mix in organic compost. Dig a hole the same size as the peat pot. Trim off the top edge of the peat pot so it is even with the soil level inside. Place the peat pot into the planting hole and backfill with soil. Water the soil well. Space multiple pear seedlings at least 20 feet apart from each other to accommodate the growing root systems. (source: ehow.com)
