Brian, I will bring down many types of seeds for you when we come down. You need to tell me if you want specific ones, otherwise you are going get hit with so many it is gonna make your head swim, hee, hee. I will bring down the ones that I think that you would like, hee, hee, that be: I don't think there are any issues with bringing seeds or plants across the border at all.
sea holly (does not bloom the first year, but a perennial thereafter)
hyssop: I suggest the cultivar that I have, Blue Fortune, I will take some cuttings today and see if I can get them started for you. I am not sure if cuttings will work this time of year, but I will give it an attempt. They would have to be babied over the winter I think. Hmmm.....thinking. Maybe I will dig up one of the mother plants and divide it. I will ponder this and figure out what I will do today with the plants, cuttings, digging, I think digging (just thinking aloud here). Maybe I will just dig a mother plant, let you plant it for wintertime outside and then you can divide in spring, that may work better, thinking out loud again, oops!!! If you don't want an established plant, tell me that, that would be important to know, I wouldn't want to tow it around with me in the back of the fifth wheel.
I will bring you seed of the "floppy" hyssop too, but I find the bees are far more attracted to the "bush" hyssop. Have the most wonderful and awesomely great day, Cindi
