The vigorous, large-growing hybrid Siberian crabapple covers itself in mid-spring with pink-tinged white blossom that become cherry-like red or yellow fruits later. This deciduous tree has a tall spreading habit to almost pyramid-like, making it a nice blend of ornamental flowering fruit tree and attractive shade tree. It is a hybrid created with the cross of two east Asian crabapples, Malus baccata and Malus prunifolia.
The slender oval leaves are dark green with teeth on the edges and emerge just after flowering starts in mid- to late spring (depending on climate or elevation). The white flowers and tinged with pink and are fragrant, attract bees, and give way to small fruits that turn either red or yellow or a blend of both. Birds relish the early autumn ripening fruits, which persist for months and are produced annually, sometimes in heavier flushes in alternate years. In autumn, the leaves turn shades of yellow.

1. Soak the seeds in water for 24 hours, to soften the outer layer.
2. Place the seeds in a damp paper towel and then fold it into quarters. Place the towel into a plastic bag and place into the refrigerator. Keep the seeds inside the refrigerator for 60 to 80 days.
3. Sow 2 mm deep in soil. After approximately 6 weeks the seeds should begin to sprout. Only about 30-50% of the seeds will germinate so plant enough!
4. Plant the sprouts into 6-inch containers filled with a well draining potting soil. Select a container that drains. Be careful not to injure the root system when planting the apple seedlings. Water to keep the soil moist, but not soggy and place the container in a sunny window.
5. When the plant is six months to one year-old, plant it outside in a location situated in full-sun and with well-drained soil. Select a planting site where the tree won't be crowded and gets good air circulation. Constantly wet soils and crowded conditions leads to disease problems and possible death.
