Aconitum degenii is a tall spindly erect to scandent forb which is perennial from rhizomes. It has divided leaves. The flowering period extends primarily from July to September. The inflorescence is paniculate and branched. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia; growing in the moisture-retentive but well-draining soils of mountain meadows. Most species are extremely poisonous and must be dealt with very carefully.
