"Garden of the Plantmaster" was Creations Unlimited’s final publication, although the adventure itself was older than the Maze of Zayene adventures. It had been prototyped as a special area in the famous Castle Greyhawk dungeons in 1974-1975, while its completed form was moved to Kuntz's Lost City of the Elders and closely tied to "Mordenkainen's Fantastic Adventure".
Kenzer & Company reprinted the adventure as "Garden of the Plant Master" in 2003.
