Malus sylvestris, the crab apple, is a species of the genus Malus, native to Europe. Its scientific name means "forest apple", and the truly wild tree has thorns.
In the past, M. sylvestris was thought to be an important ancestor of the cultivated apples (M. domestica), but these have now been shown to have been originally derived from the central Asian species M. sieversii.
The flowers are hermaphrodite and are pollinated by insects. Its leaves are food of the caterpillars of the Twin-spotted Sphinx (Smerinthus jamaicensis) and possibly the Hawthorn Moth (Scythropia crataegella). (info source: wikipedia.org)

|Germination||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.
