The Plantsman

September 2017

In this issue of The Plantsman we look at Petrocosmea in cultivation, phosphorus toxicity and Australian plants, the RHS trial of Stipa and allied grasses, overwintering conservatory plants in a dried state, an unusual Himalayan Vaccinium, the origins of edible brassicas, Chelsea Plant of the Year, exotic Beschorneria for gardens, and a biography of Joan Loraine.
