Bean's Trees and Shrubs Hardy in the British Isles
The British master himself and one of the most
influential woody plant guides in history. It
took me 10 years and about $150.00 to
find all the volumes on this shore. Now it's free.
Hibberd's New and Beauitful Leaved Plants
One of the mostly lovely plant books
ever printed. Stunning images and expert
commentary. Hibberd adored variegation.
Wilson's A Monograph of Azaleas
From the collector of many taxa himself,
this is splendid reading for even the
most experienced lover of the genus
Carriere's Trait General des Coniferes
One of the classic, core conifer books of the last two centuries. It's
amazing how many modern popular conifers this man named. Ever
see Carr. after a name? That's him.
Sudworth's Nomenclatural of the Arborescent Flora of the United States
I regard Sudworth as perhaps America's first great woody plant taxonomist. This is a stunning catalog not just of species, their synonyms,
common names, but also numerous cultivated varieties
Bailey's The Nursery Book
This was one of the most widely distributed nursery guides in the US and from the great one himself. I've always liked calling propagation by his terms of seedage, cuttage, and graftage. It seems so proper and academic.Bailey invented the word "cultivar" and conspired to be a "horto-botanical" writer, meaning that both horticulture and botany were blended into the whole. By the way he did all this while Dean of the College of Agriculture at the Ivy League Cornell University.
