RHS Plant Monographs

These horticultural monographs are authoritative guides to the identification, botany and cultivation of garden plants

About the series

Offering total knowledge of the topics they cover, the first RHS Plant Monographs for more than half a century mark a new era in horticultural and scientific publishing. These beautifully produced volumes include not only comprehensive information about wild species but unparalleled coverage of the cultivars which enrich our gardens. Telling tales of people and places, these books further appreciation of every aspect of plants.

Why monographs?

Through these scientific works we hope to encourage the enjoyment and use of a wider range of cultivated plants in gardens and landscapes. Furthermore, we hope to improve plant identification and promote plant conservation, cultivation, use, selection and plant breeding.

These monographs will, over time, strengthen the global knowledge bank on gardening and garden plants, and act as a confirmation of the importance of the RHS as an international centre of excellence of horticultural taxonomy.
