English hawthorn is a small, low-branched, round-headed deciduous tree from Europe. It bears showy clusters of white flowers in late spring, followed by small spherical fruits that ripen red in fall. The small, lobed, glossy dark green leaves do not brighten in fall. The stiff spreading or ascending limbs brandish long spines, which are beautiful when frosted with snow.
Although tolerating a wide range of conditions, this tree does best in well drained soil and full sun. It fares poorly in regions with hot humid summers. In moist climates it often suffers from leaf blight, which can defoliate trees by midsummer. Where it does well it makes a lovely specimen tree with year-round interest. Site this tree where its spines will not harm pedestrians and vehicles. It sometimes escapes gardens, and is considered a weed in some areas. (info source: Learn2Grow.com)

|Germination||1. Wrap the hawthorn seeds in a moistened paper towel. Place the paper towel inside a sealable plastic bag. Store the seeds this way for 90 days inside a refrigerator to cold-stratify them.|
2. Fill a 1-gallon plastic pot with a mixture of equal measures potting soil and compost. Sow two hawthorn seeds in the pot to a depth of 1/4 inch. Water the pot to a depth of 1 inch.
3. Place the pot outdoors, either against a south-facing wall or in a cold frame, where they will be exposed to normal outdoor temperature fluctuations and precipitation.
4. Water the hawthorn seeds only during extended periods of dry weather to keep the soil moist, at a depth of 1 inch. Avoid overwatering the hawthorn seeds since they might rot.
5. Check the pot periodically to ensure no birds or rodents have taken the hawthorn seeds. Place mesh over the top of the pot if it appears that creatures are foraging for the seeds.
6. Watch for signs of germination starting 18 months after sowing. Thin the hawthorn seedlings once they reach 2 inches in height. Remove the less vigorous of the two seedlings.
7. Keep the hawthorn seedling in the pot with evenly moist soil until it reaches 12 inches in height, then plant it in a permanent bed with partial sun. (source: eHow.com)
