When I visited Butchart Gardens on Vancouver Island with my sisters maybe ten or so years ago now, I got seeds for these Maltese Cross, lychnis calcedonica. do you see how each little flower forms a Maltese cross? I have seen them growing in David and Kate's yard in Anchorage and they were about three feet high and just gorgeous. Mine limps along, but I really like it so I keep an eye on it and keep hoping for more. This is the best photo I got, but usually the heads are bigger, a cluster about 2-3 inches across.
