I grew some red perilla last year & have quite a few growing again this a year (is it a perennial or annual?). What can it be used for? I have it growing by my beautiful Northern Sea Oats plant (now putting out those pretty 'eyelash' seed pods). I also have parsley going to seed & seedlings growing all over & wonder if I should let these plants grow or are they not like the parent plant? Some herbs seem to want to 'take over' & I also have to thin the Sweet Annie to just a couple of huge plants each year. I love to cut & dry Sweet Annie & place in a flour sack & hang in the closet for its lovely aroma!
