Readily multiplies from plant. Thought to sometimes be a bit invasive. Flower stems are fine and having other plants or a fence to support flowers might be a good idea. Plant itself is low growing (less than 6 inches) even though the flower stems are 3-4 feet in height.

By picking spent flowers daily the plant will produce more flowers along flowering stem for pretty much continual blooming throughout the summer in my climate. If picking spent flowers is too much work, simply cut stems for a second flush of flowers later in the summer.
