he Hostapedia by Mark R. Zilis is a large 1125 page hard-bound encyclopedia featuring over 7400 hosta descriptions, A-Z. There are over 1897 color photos. This is the most definitive work on hostas to date. The author is the same who published the very popular Hosta Handbook which is out of print, but continues to be sought after by hosta collectors. The descriptive format for each hosta in this encyclopedia is nearly identical to that of the Hosta Handbook. That is, for each hosta, the following information is included: name, name of hybrid & hybridizer (if known), origin, history, description of hosta (size, coloration, habit, etc), flower, status of availability, author's comments, similar hosta types, significant sports and significant seedlings. This hosta guide is the ultimate guide for anyone interested in hosta information. Published in 2009 by the author's hosta nursery: Q & Z Nursery, INC.
