Summary

Sickle-leaved hare's-ear Bupleurum falcatum subsp. falcatum is an umbellifer that has a very limited distribution (currently one native locality) in the UK. Seeds (1,200) were collected from the single wild population in Essex (southeast England) and propagated using conventional techniques over the winter of 2007/08. A high proportion germinated (859; 71%) but 93% of the seedlings subsequently died in the spring and summer of 2008. The 57 young plants that survived were planted out at the donor site in January 2009, established well (all but one alive in July 2009) and competed strongly with other species already present. All grew well, all flowered and some produced seed. Growth was similar to that of plants in the nearby established colony.
