Answer: Your state nurserymans association may offer some, or if you attend trade shows there may be some available from plant suppliers as "freebies". You might check with your local wholesale suppliers. Otherwise you might try a poster shop -- for instance http://www.art.com offers a variety of different styles in their "botanical" category and http://www.allposters.com offers a big selection. For example, a poster of various chili pepper varieties is included under food/vegetables; they have landscape and botanical sections, too. Good luck with your search!
