Stephen Butler has maintained a collection of Libertia at the Zoo for many years. As well as collecting a wide range of these plants he has prepared herbarium specimens and pictures and identified naming issues which all proved a significant help to Julian Shaw, the Royal Horticultural Society’s Registrar, who has been conducting a review of the genus Libertia over the past number of years.
When Libertia chilensis and L. ixioides are grown in gardens hybrids regularly occur between them – distinguished by wider leave than ixioides and a much more open inflorescence than chilensis – and it is botanically useful to have a name for these hybrids and Julian Shaw has named such hybrids “Libertia x butleri” in recognition of Stephen’s work.
Stephen is Curator of Horticulture at Dublin Zoo, Chairperson of the Leinster Branch and a member of the Executive Committee of the IGPS and the person who has organised the IGPS members’ Seed Distribution over many years.
Well done, Stephen!
