This may be off topic but I hope someone can lead me to a source for Lewisia seeds. My wife has purchased some Lewisia from our local Trader Joe market. I looked them up in a general book I have and became interested in them. I would also be interested in more information about the genus that is named for Meriwether Lewis. I also am interested in books on bulbs. Is it best to get a book on a specific genus or is there a good general publication? Thank you all, Sam Hay Yorba Linda, CA Zone 10
