Sulphur Heart Persian Ivy. I first saw this cultivar on the walls of a small British hotel on the outskirts of London back in the 1990's.I was with a group of other nurserymen and Clemson professors. We all wanted a start of it but were too shy to ask permission for a few cuttings. But upon visiting Mary Alice and Bear Woodhams' fabulous garden only a about a mile from our nursery, I noticed it growing up one of her pine trees. Most of the "cutting" wood was so high that we had to get an extension ladder to reach viable cuttings. Mary Alice could not remember where she had gotten her start from, but I am sure that it has been around for some time. This is one of the tougher species of ivies that I know. The solid green species form will even grow in full sun here in the Deep South, and we don't experience the die-back and root rot that we often experience with English Ivy, Hedera helix. It does exceptionally well in containers also. The leaves of this species can reach 6 inches across and have a distinct herbal scent when crushed. I would recommend planting it in filtered sun to shade in the Deep South, but further north, I am sure that it would do quite well in sun. It can be used as a ground cover, but my preference, since it is a self-clinging vine, is to let it grow up a textured surface such as a stone or brick wall.
