Interesting Facts
The most distinctive feature of bear's breeches is its flowers. There are dozens of flowers on a bear's breech, but its flowers do not bloom proudly all at once, but hide shyly under the leaves, only showing small heads, looking like the tail of a shrimp. Its peculiar flower pattern makes it irresistible to not stop and take a look.
Name Story
Bear's breech: According to the plant taxonomy expert William Stearn, the name Bear's Breech comes from the medieval (Pre-Linnaean) latin name "Acanthus sativus branca ursina" which means "Cultivated Spiny Bear Bract". This is because they felt that the curved bracts on the flower stalk looked like a bear claw.
