  1. White White Ash “Autumn Purple” (FraxinusAmericana)

  2. Scientific Classification • Kingdom: Plantae • Division: Magnoliophyta • Class: Magnoliopsida • Order: Scrophulariales* • Family: Oleaceae • Genus: Fraxinus • Species: Americana

  3. Tree Description • Height 60-80 ft • Extreme 90 ft • Trunk 2-4 fta • Hardwood Tree • Wood is hard, strong and elastic • The bark is rough dark gray, deep diamond shaped furrows and forking ridges.

  4. Leaf Description • Deciduous • Opposite • Compound • Pinnately compound • Margins toothed • Leaflets similar in size and shape • Leaflets with short stems • Leaflets irregularly toothed, or only near tip • Twigs and leaf stalks smooth

  5. Root System • White ash generally forms a taproot that in turn branches into a few large roots • vertical roots, single lateral branches develop at intervals

  6. Reproduction • flowers appear with or just before the leaves in April and May • Pollen shedding from an individual tree usually takes 3 or 4 days • The pollen is carried by wind as far as 328 ft from the point of dispersion • Female buds are completely open a few days after they begin to swell • Almost 99 percent of the fruits (samaras) contain one seed, about 1 percent contain two

  7. Fruit • Single winged • Elongate • Seed cavity round or flattened • Fruit straight to 3 inches • Tan • Attracts birds; fruit, twigs, or foliage cause significant litter; showy

  9. White ash grows most commonly on fertile soils with a high nitrogen content • Soil moisture is an important factor affecting local distribution • White ash is found in various topographic situations • In the Central States it is most common on slopes along major streams World distribution

  10. Habitat/growth environment • Deep, moist, well drained soil, pH adaptable, full sun

  11. Economic importance • juice from the white ash leaves can be topically applied to a mosquito bite to relieve swelling and itching • best known as the wood most often used • baseball bats hockey sticks, billiard cues, skis and oars, and as tool handles because of its strength, light weight, and shock absorbency • also used for chairs and other furniture pieces because it is one of the best woods for steam bending due to its flexibility
