Wish spring would hurry? Plant Rijnveld's Early Sensation this fall and expect blooms in January if you live in a warm climate, a little later if you're in a cold region. While other spring flowers are still sleeping, this early riser will be adding welcome pools of cherry yellow to your groggy garden. If Mother Nature delivers a surprising cold snap, don't worry. Rijnveld's Early Sensation is tough as well as pretty and will laugh off light snows and temperatures as low as the teens. Deer and rodent proof.
