If by "exchanged" you mean, I got my SCOBY from you and have since passed on babies to a good many people, then yes, that's true. :) You live in Vermont...?

I don't know what exact plant drew the wasps, but I can tell you that this is my first year with anise hyssop, and my first with hornworm cemetaries. I have catnip and comfrey for the first time, too, but the comfrey is not flowering now. (It is giving me leaves which have powerful healing properties, as advertised. :) I actually planted the hyssop to try to repel aphids from my kale, where they bred prodigiously last year (and thus far are under control this year, we'll see).
