Here's one of the expert perennial gardeners secrets. This little-known plant is a must-have perennial. It is a close hybrid of the native species, but much better. Best of all, it adds big color to a border or meadow for months, not just a couple of weeks. Unlike many others, the big golden double flowers (3 to 4 in. across) keep coming and coming, especially if you remove the fading ones.
The common name isn't really correct either, since it suggests tall gangly sunflowers. This plant is not very tall, usually just 3 ft. or so, and the flowers are large and a beautiful rich gold in color, much more like an award-winning chrysanthemum than a sunflower.
This is one of my top 10 favorite perennials, a great colormaker wherever it grows.
