Bright yellow male catkins. Reddish cone-like female flowers. | 15 feet | Tag alder is a suckering, multi-stemmed shrub or small tree found along stream banks, pond margins and in wet meadows in the eastern US. This species is tolerant of prolonged flooding as well as temporarily dry situations. Monoecious, tag alder produces both pistillate (female) and staminate (male) flowers on the same plant, making for a attractive show in early spring. The fruit, a woody dark brown cone like catkin, ripens in late fall and persist thru the winter. Tag alder leaves turn yellow and orange in color in the fall. | Bright yellow male catkins.
