Kniphofia: The Complete Guide by Christopher Whitehouse will be published by the Royal Horticultural Society in May 2016 at £40.
With a foreword by Sir Nicholas Bacon, president of the RHS, the book is the first in a new series of RHS horticultural monographs, guides to the identification, botany and cultivation of garden plants.
Kniphofia or red-hot poker, have been cultivated in Western gardens for more than 300 years but, until now, there has never been a book on the genus.
The RHS plant monograph's reintroduction is "an important recognition of fundamental RHS principles", says the RHS. The last monographs published solely by the RHS were George Johnstone’s Asiatic Magnolias in Cultivation (1955) and Frederick Stern’s Snowdrops and Snowflakes (1956). This new series of monographs will include comprehensive information about species, but their strength will lie in their extensive illustrated coverage of cultivars, says the RHS.
The next tome out in 2017 will be on ivy (Hedera).
