Klehm's Song Sparrow has the fl double for $60.00. Expect to pay $50 to $60 for the double and $35 to $45 for the single. My usual source, Hidden Springs Flower Farm is sold out. They are open for orders early Spring and sell out quickly. There are several sources available on ebay etc but I never purchase from them. Only the major nurseries although some of the mom and pop growers are trustworthy. All the major vendors I have dealt with bill the credit card in the Spring when the order is placed even though they do not ship until mid-September to mid-October. Essentially, you own it when you order it.
