-31% Black Locust (Robinia Pseudoacacia) 20 seeds (#32)

Though pretty and fast-growing, black locust is weak-wooded, short-lived and generally weedy. It is hardy, deciduous and forms a broad, upright canopy when mature. Some are more shrub-like. Natural populations are believed to have originated from the eastern United States, particularly along the Appalachians and Ozark Mountains, but have spread across much of the United States and up into Canada.
Green to blue-green compound leaves (leaves comprised of many small leaflets) cover its coarse, thorny branches through summer and turn shades of yellow and tan in fall. In spring, it produces pendulous clusters of fragrant, ivory, wisteria-like blossoms. Pink-flowered cultivars are also available. The fruits are dark brown, flattened pods filled with seeds that mature and split open by fall. Its deeply furrowed bark is variable in color and moderately attractive.
Black locust requires full to partial sun and withstands many well-drained soil types. It tolerates difficult sites, infertile soil and self-sows aggressively—factors which help explain its weedy success. The brittle branches of black locust break easily in storms and high wind and damaged trees tend to sucker.

GERMINATION INSTRUCTIONS
1. Use a pair of baby nail clippers to pinch off a piece of each Robinia seed's outer seed coat. Don't cut too deep — just enough to allow water to penetrate to the embryo.
2. Heat water until it is hot to the touch and pour it into a shallow bowl. Place the Robinias seeds in the water and let them soak for 48 hours. They should swell during this period. If they don't, cut the seed coats again and repeat the hot water soak.
3. Fill a small nursery pot with sand and set the Robinia seeds on the surface. Cover it with a 3 mm (1/8") layer of moist sand.
4. Place the pot on a heat mat set at +30c (86F). At sundown, lower the temperature to +20C (68F). Raise it to +30C (86F) in the morning. Continue this until the Robinia seeds germinate in 10 days to five weeks. (source: ehow.com)
