I just received my copy and have browsed through it enough to have a very favorable impression. Any one else have some views to offer? The same author also has The Hosta Handbook (2000) and Hostapedia (2009). The latter is absolutely essential in my opinion, especially if you want to develop your biceps! Pick up a copy and you will know why! Seriously, it is so extensive, with photos of almost every hosta listed; I refer to it constantly. But the new Field Guide is light-weight and easy to use, has full info on 272 of the hostas which Zilis considers "essential" and each entry includes information on other related hostas. I compared my collection of about 500 and learned I have only 101 of the 272. Does that mean I have 399 superfulous hostas? [just kidding] Finally, this new book completely replaces the 2000 Handbook because so much has happened in the hosta world in the last 14 years; it is more than just an up-date.
