Happy Plants will tell you everything you need to know about how to boost your mood with the happiest house plants, herbs, flowers and fronds.

It has long been known that immersing ourselves in the natural world makes us happy. But what are the happiest plants? How do you make the most of their joy-bringing properties like scent, taste and colour? And how do you bring this positive plant power into your life?

Happy Plants features 100 planty reasons to be cheerful, with engaging and authoritative text and gorgeously colourful images from leading gardening charity the Royal Horticultural Society. From cut flowers and containers to forests and fields, each entry will describe how plants can fight sadness, induce calm and otherwise brighten your day - and how you can make these accessible species happy, too.
