I am a professional landscape designer, and I have become a huge fan of Heucheras and Heucherellas. Their incredible variety of foliage colors makes them a wonderful plant to use in many situations. They are simple to maintain, easy to grow, and come in foliage colors from bright golden chartreuse with magenta midribs, lush greens with gorgeous natural-looking pink flowers, to deep velvety purples and rich chocolate ruffles.
This is a truly wonderful resource for fans of these plants. The first part of the book has over 50 pages filled with multiple color photos on each page, of every kind of Heuchera or Heucherella you might want to know about. This is great for getting a glimpse of some of the newer varieties that haven't reached our local nurseries yet, and for comparing the subtle and not so subtle variations in their foliage, flower, and habit. I haven't found any Heucheras that are available to me that are not covered in this book, and he covers a lot that I haven't seen yet.
The text which comes after the truly awe-inspiring array of photos in the beginning is helpful and interesting. He gives a lot of background information that the average home gardener might skip over (history, propagation, how they are named and botanically classed), but that I personally found fascinating.
He also gets right to the meat of the matter in his discussions of pest problems and how to solve them, how to combine some of the outrageous foliage colors found in Heucheras and Heucherellas with other garden plants, and how to design with them and use them successfully in the garden.
There is also a reference portion where he discusses each plant and variety, its parentage and what that tells us about what they like in the garden, and describes many varieties in great and useful detail.
I have been waiting for a book on Heucheras for a really long time, and I am so glad that this one was so well worth the wait.
