About
Bupleurum rotundifolium is an upright, branching annual that reaches up to 30 cm in height. It features rounded leaves, with the upper leaves encircling the reddish stem. At the tips of each stem branch, you will find clusters of small yellow flowers surrounded by leaf-like bracts. Once a common weed in cornfields, this species has become rare in its natural habitat but is now valued as an attractive addition to garden settings.
About the genus
