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.
Water:
Caltha thrives in moist environments, favoring consistent moisture. While it can tolerate brief dryness, weekly watering is essential to replicate its natural habitat. As an herbaceous perennial, caltha 's growth is influenced by water availability, necessitating careful irrigation during active growing seasons.
Propagation:
Propagation of caltha primarily involves division and seed sowing. Essential conditions include moist, well-draining soil, partial to full sunlight, and moderate temperatures. Methods include spring division of root clumps and surface sowing seeds in bright, cool areas until germination, requiring care and patience.
