I currently have a small but steep (45 degree) hillside area mostly covered in ivy. Part of the hill area is in part shade, and part is in full sun. The ivy's not in the best shape, and it's constantly being overrun with weeds, especially creeping buttercup. I'd like to replace it with something useful/productive, like for the kitchen or crafts or whatever. But it's right in front of our house, so I'd also like it to be something that looks ok all year, like ivy (theoretically). One thing I'm considering is sweet woodruff, because I hear it has a wonderful sweet hay smell when dried and brought inside for potpourri, etc. We also just got some perilla plants which might work, but I'm afraid the slope would be too much for them. Thanks for any ideas you might have.
