At the right, you can see purple cone flower and amaranth (really, you can). Sorry about the fuzzy quality of this photo.
Purple horsemint and wild hysop are allowed to self-sow themselves as filler among the other plants. Care is taken to keep the area around the roses clear so they don't mildew too badly. Horsemint has a deep purple/brown leaf and a distinctive aroma, but is not edible as far as I know. It presents a stalk of pale blue flowers late in the season and can provide a nice dry feature in the winter garden. |
Wild hysop reappears each year from roots and seeds. It has a dramatic stalk -- up to 2 feet long -- of small but vividly purple flowers which last for weeks. Often it reflowers later in the season.
