Add to My Garden White caltha
Caltha obtusa
White caltha are cold-hardy, flowering perennials with small, often clustered white to bright yellow blooms. The plants contain noxious chemicals that make them unappetizing to wildlife, but their flowers attract a variety of beetles, bees, and hoverflies. The seeds of several species have developed to be spread by water, usually via rainstorms.
