About

Carpathian monkshood is a tall plant with dark blue flowers, easily noticeable at the end of summer in mountain meadows, by streams, in tall grass, and on rocky places in the upper forest zone. The main range of the species is the Western Carpathians in Poland, Slovakia, and the Czech Republic; it is less common in the Ukrainian and Romanian Carpathians.

The plant grows to 1 m and higher with a straight, sturdy stem. The leaves are palmately divided and deeply lobed. The flowers are blue-violet, gathered in a dense elongated raceme. Each flower has a characteristic shape: the upper petal-like sepal forms a 'helmet' or hood under which small nectaries are hidden. Only bumblebees, strong enough to get under the helmet, pollinate the plant. It blooms from July to September.

All parts of the plant, especially the tuberous roots and seeds, contain aconitine — a potent nerve poison. Poisoning causes numbness of the lips and tongue, nausea, heart rhythm disturbances, and can be fatal. Therefore, the plant should not be picked with bare hands, and hands should be washed after contact.

In Poland, Carpathian monkshood, like all monkshoods, is protected. In Ukraine, the species is not listed in the current Red Book, but there are also red-listed aconites in the Carpathians. The best behavior around the plant for everyone is to admire it from a distance and keep children and dogs away.
