Executive Summary

I assessed the availability of invasive plants in Florida nurseries before and after publication of a voluntary “do not sell” list in 2001. The list was created by the Florida Nursery, Growers and Landscape Association (FNGLA), in cooperation with the Florida Exotic Pest Plant Council (FLEPPC), and included 45 known invasive plants. I compared current availability of species on the list to that in 1999 in a print catalog, and also assessed current online availability (i.e., sales via the internet).

In the catalog, 18 species on the “do not sell” list were available in both 1999 and 2004. They were being sold at 76 nurseries in 1999, and 81 nurseries in 2004. In 1999, ten of those nurseries had more than one species from the list, while in 2004 only five had more than one species on the list for sale. The number of FNGLA members in the catalog selling species on the list increased from 26 in 1999, to 47 in 2004. Fifteen species from the list were available both in 1999 and in 2004, and 19 nurseries sold species from the list at both times. Nine of those nurseries were FNGLA members.

I found 22 additional Florida dealers selling species from the list over the internet. Notably, 13 sold more than one species from the list, and 15 were FNGLA members. An additional 8 species from the “do not sell” list were available online, giving a total of 26 species from the list available via the catalog or online. Overall, then, almost 60% of the plants on the “do not sell” list were available in 2004 at Florida dealers.

Thus, I found no evidence that the program reduced trade in plants on the “do not sell” list in Florida. Greater promotion of the program might be beneficial, as about 75 of the current catalog-based dealers only have a single species available. Still, factors such as online availability, economic realities affecting small businesses, and plant sales by “big box” retailers pose serious challenges to the effectiveness of such voluntary programs.
