The bright blossoms with their bright gold stamens atop tall stems grace my garden during late summer and last until fall. The simple elegance of the plants is perfect in an intimate setting so that the flowers can be enjoyed up close. The flowers are preceded in spring by attractive rich green foliage that looks like grape leaves. The plants stand about 12” tall and form a beautiful ground cover. They have been vigorous growers in both my Annapolis and North Carolina gardens and I have had to pull out handfuls of them in the course of the summer to give the neighboring plants and chance to grow. They are easy to remove, well worth the effort, and I would not be without these beautiful and useful plants.
