Known variously as hare’s ear, thorough-wax, and thorowax, Bupleurum rotundifolium is an unusual annual that produces circular clusters of greenish yellow flowers over blue-green leaves on upright stems. It usually reaches 1 to 3 feet tall, but in rich soil, it can get about 4 feet tall. Spring-planted seeds tend to bloom in mid- to late summer; in following years, the self-sown seedlings often begin in late spring to early summer. Both the flowers and developing seedheads are interesting additions to fresh bouquets. Hare’s ear also makes a nice filler in a young perennial or mixed border while you’re waiting for the permanent plantings to settle in and spread out. It pairs well with a wide range of companions but is particularly beautiful with blue and purple flowers and purple foliage partners. Full sun to light shade. Annual.
