With its round, spreading crown and elegant slender leaves that color beautifully in fall, this native of Southwest Europe and northern Africa makes a terrific deciduous shade tree. The pinnate leaves have 7 to 13 lance-shaped leaflets that are narrower than those of most other ashes, giving the tree a relatively fine, lacy texture. The leaflets are dark glossy green above and paler beneath. Foliage turns yellow or purple in fall. Inconspicuous flowers in spring give rise to winged seeds that mature from light green to pale brown. This straight-trunked tree has light brown bark that is smooth when young but becomes furrowed with age.
This ash grows best in neutral to alkaline, fertile, moist, well-drained soil in full sun. However, it tolerates acidic soil and some drought. It is a beautiful shade tree for a park, large yard, or streetside. (info source: Learn2Grow.com)

|Germination||1. Remove form the ziplock bag and keep the seeds in an paper envelope in the freezer till ready to plant or for the winter. This process, called dry cold stratification, mimics weather conditions outdoors and is necessary for ash seed germination.|
2. Remove the seeds from the refrigerator in mid-April. Fill a seed tray or flat with soilless potting mix and sow the ash seeds on top. Cover with an additional 1/2 inch of potting mix and moisten thoroughly.
3. Set the flat in a sunny, warm room, keeping it moist for the next two weeks. Seeds will germinate and sprout.
Thin the seedlings to 6 inches apart. Transplant them into individual pots full of moist potting soil when they reach heights of 2 inches. (source: ehow.com)
