The Colorado Dahlia Society publishes what they call the “Biglist”. This list is very handy when trying to locate a source for a specific variety.

Just as an example, I see 4 suppliers that probably have ‘Bahama Mama’
Also, it is very convenient to have links to 65 different dahlia suppliers… this makes for some serious shopping:)
