Japanese angelica tree is a deciduous shrub or small tree native to China, Korea, Japan and the Russian Federation. It occurs in Ontario, Canada and throughout much of the northeastern U.S. from New Hampshire south to Maryland and west to Michigan and Illinois. It also occurs in Oregon and Washington. It can grow to 30 ft. in height. It has prickly stems and large compound leaves that are 2 or 3 times pinnate. The leaf stalks and flower stalks may have prickles. The main lateral veins of the leaflets continue all the way to the teeth at the leaflet margin. Flowering occurs late July through August and fruits mature in August and September. Flowers are small and white and emerge from tips of stems in broad umbels 1-2 ft. across that lack a central stalk. Fruits are black and about 1/10 in. across. Angelica-tree is becoming increasingly common in the mid-Atlantic and should be watched and controlled as needed.
