The best plant to spoil a pastel cottage garden.

It is the brightest orange in the plant world. (That I've seen) Those that see my garden never forget it, and ask about it later.. It is a compact version of C. sulphureus of extreme color. They begin blooming in early August, and the plants will continue to be 100% covered with flowers until frost if deadheaded. It is a true front-row border plant in size, but be warned, as a border it may steal the show and distract from even the most impressive plant behind it.

Here's to the reason that road-construction signs are blaze-orange,
