Light Brown Apple Moth (LBAM)
My plans to import Salvias from Europe and California may have run into a roadblock because of the Light Brown Apple Moth (LBAM). Quarantines of this Australian escape are listed for the San Francisco - Bay area and Thousand Oaks, California, southern England, New Zealand, and Australia. I think that the shipping of perennials has been banned until controls have been established.
The English and California areas are the homes of the best collections of Salvias, so check with your nursery and friends before swapping Salvia cuttings and plants.
Google the pest for ample info on it. It can attack up to 250 different species (including lots of commercially important vegetable and fruit crops), and could naturalize in USDA Zone 8 or warmer. If interested, I can post some of the relevant URLs on this pest.
