A host of new house plants have appeared during the last ten years.These plants are in the shops, but they are not in the books – until now.There are in-depth features on bonsai, orchids, bromeliads, Christmas flowers, herbs and many more.Roomscaping is introduced – the way to use house plants alone or in groups as decorative features rather than as green or coloured pets.The problem section answers the main difficulties with indoor plants – why they don’t flower, why they die, how much to water and much more.There’s even a miscellany – a collection of bits and pieces from the lucky bamboo story to the easy way to measure humidity.
