Common Names: Thorow-wax, hare's ear, hound's ear Seeds of B. rotundifolium are sold for gardening and the plant is used in flower arrangements. A member of the carrot family (Apiaceae), B. rotundifolium possibly originated from Asia. Stewardship summary Most of the information available on this species concerns how to grow it since it is useful for its medicinal constituents. Numerous papers about the secondary compounds (saponins) of Bupleurum falcatum were available and most information below is on this species. Natural history The seeds of B. falcatum often have a low rate of emergence and require a long emergence period. High and constant soil moisture increased the number of emerging seeds and also the time period for emergence. Seed germination rates were highest at 15° C. The germination rate was very low at 25° C and zero germination was observed at 35° C. Management/Monitoring Preventative measures Mulches are not recommended because they increase soil moisture and may result in higher germination of seeds. Dry stressing 7-month rosettes and bolting plants of B. falcatum (keeping the plant near the wilting point) demonstrated that the aerial parts of the rosette were reduced but dry stress did not affect the growth of the root in both the rosettes and bolting plants. Mechanical Control If hand pulling, the use of gloves is recommended since the secondary compounds common in the Apiaceae family can irritate skin. Clipping the aerial part of the plant may actually increase the weight of the root. Techniques such as deep ploughing may also increase root weight. Disbudding increased the viability of plants and increased the weight of the root. Chemical Control A dicamba and 2,4-D mixture may provide control. 2,4-D alone will reduce populations but not kill all plants. Roundup may also be an effective control measure (J. DiTomaso, personal communication). For wild carrot ( Daucus carota ), glyphosate did provide >74% control when applied at 0.84 kg ai/ha. 2,4-D ester was less reliable when applied at 1.12 kg ai/ha, providing 18% control at one site and 88% at another (Stachler and Kells, 1997).
