Caltha — 6 species

Most Caltha are not pet-safe. Of the 6 Caltha species in the Growli library, 6 (100%) carry a toxic or mildly-toxic ASPCA classification and 0 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.

Most Caltha do best in bright indirect light. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.

Caltha are moderate to grow: the main requirement is a genuinely bright spot out of harsh midday sun. Get the light right and the rest of their care follows.

Growli's care library covers 6 Caltha species and varieties — browse them all above. They share a similar light, water and soil pattern, so once you learn one Caltha, the rest follow closely.
