Genus guide
Acorus — 12 species
Part of the Pond & aquarium plants family (Pond & aquarium plants)
Acorus is a genus of grass-like, rhizomatous perennials native to wetlands and stream margins across Asia and North America. Acorus gramineus and its variegated cultivars form low, arching fans of slender foliage with a faint anise scent. They thrive in bright indirect to full sun and demand consistently wet or waterlogged conditions — they are ideal at pond edges, in bog gardens, or as aquarium marginals. Keep soil perpetually moist; they will not tolerate drought. All Acorus species are toxic to cats and dogs and should be kept away from pets.

Acorus — frequently asked questions
Are Acorus plants toxic to cats and dogs?
Most Acorus are not pet-safe. Of the 12 Acorus species in the Growli library, 10 (83%) carry a toxic or mildly-toxic ASPCA classification and 2 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Acorus plants need?
Most Acorus 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.
Are Acorus easy to care for?
Acorus 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.
How many Acorus varieties are there?
Growli's care library covers 12 Acorus species and varieties — browse them all above. They share a similar light, water and soil pattern, so once you learn one Acorus, the rest follow closely.
