ID Features: Pinnately compound leaves resemble those of Fraxinus, but leaflets. are irregularly shaped. Green twigs with reddish brown upper surface have waxy bloom that can be. rubbed off. Broken twig has a strong, acrid smell. Buds covered with silky white hairs. White, solid pith in twigs. •

Landscaping

Landscape Uses: An "alley cat" tree. Often used in shelterbelt plantings in the Northwest. Has possibilities on difficult sites and areas that flood seasonally. Huge flocks of migratory birds (Evening Grosbeak, Cedar Waxwing) usually. strip all seeds from this tree as they pass through. • Liabilities: Susceptible to a wide range of diseases and insect pests: leaf spot. diseases (anthracnose can be extreme in rainy weather); cankers, sapstreak and. trunk decay; caterpillars (including forest tent caterpillar, green striped. maple worms; boxelder bug; assorted leafhoppers, borers, mites, aphids and. scales. Trunks can "weep" from internal decay for 15 years or more before the. tree disintegrates in a storm.. Seeds germinate well, creating a weed problem. Weak wood breaks easily in storms. A short-lived tree.

Habitat

Occurs natively on stream banks, edges of swamps and lake shores.

Reproduction

Duration: Perennial

Growth

Culture: Transplants easily. Performs well on poor, wet or dry sites, in areas or soils of extreme pH. levels; withstands flooding.
