I was thinking about trying something this year with a square raised bed caged area on the front of the property...something less than 4 foot square. I'd have to remove a small tree I have there that I've given up on. I want that for Asclepias asperula. Only thing is I'd have to water it until it is established somehow. In my climate, that is necessary. My place is somewhat a hostile environment for most of the milkweed species, so I'm limited to few species. Wish milkweed was easier to grow! Swamp Milkweed Leaf Beetles like it here, unfortunately. And critters who love to dig...the bane of my gardening life!
