Some plants just don’t take a hint and this is one of them. It is a cheerful, adventuresome member of my hot border and just won’t reign itself in no matter how much I pull out each year. I am really not complaining because it is a great addition to my border and I would never want to be without it. The bright yellow flowers are borne in clusters on the top of their 18” stems and put on quite a show. As the bloom fads they want to keep on growing so I pull them out with abandon to make way for other plants. No problem, they come back the next year as abundant and floriferous as ever so I keep repeating this yearly routine and am always glad to see them return so faithfully.
