A native of the Himalayas, Aconitum ferox is known as blue aconite in India. In fact, the blue of its bloom is so rich that it's said to have turned the Indian god Shiva blue. As a high altitude mountain flower, it's one aconite that can thrive in rocky soil and full sun. It's also the most toxic of the Aconitums, so wear your gardening gloves with it.

Aconitums are commonly known as monkshood, because the upper
sepal of each flower resembles the hoods of medieval monks. They
attract a variety of butterflies and moths, and are the primary food
source for Old World bees. Another common name, wolfbane, refers to the
poison made
from this plant's roots, which was used to tip hunting arrows.
Medicinal (and poisonous) uses of this plant date back to ancient times.
