Thousands of young plants are raised from seeds every year, the Ash being a valuable timber tree as well as an ornamental one. There are several varieties, such as aurea, with yellowish bark; also a golden-leaved weeping form, laciniata, with deeply cut leaves. The Flowering or Manna Ash (F. Ornus) makes a fine tree. It has drooping clusters of white flowers. There are other species, like americana, the White American Ash; and pubescens, the Red or Black Ash. The choice varieties are grafted on common stocks.
