Well I'm so glad I stumbled on this thread! I just bought 1/4# borage seed to plant in scattered places on the 42 acre place with a getaway cabin we bought 2 years ago. Was going to wait until October to sow them to avoid the scorching heat we're having right now. There are lots of spots to plant them around the cabin itself, inside the fenced yard: full sun, part sun and lots of full shade (we have mostly oaks and hickory nut trees around the cabin).
My plan is to broadcast some of the seeds in large clumps here and there in view of the cabin front porch. Then I also want to sow some clumps in the side pasture and a few at the back of the cabin where the most shade is. That way I can see where they do best over time. Hope they will eventually re-seed themselves. Currently, yellow and white wildflowers (wild daisies, and bastard cabbage) beautifully blanket the pastures from late summer-fall, so we do not mow our 42 acres except inside the fenced cabin yard. We're leasing it for 12 Brangus to graze on, which significantly reduces our property taxes. I'm hoping the pretty borage will do OK in the pasture, somewhat protected by all the taller grasses and wildflowers around it. Will keep my fingers crossed. Bluebonnets would be pretty, but they are VERY difficult to get to germinate. But I love them and may give them a go out there, too.
