Gunnera comprises large, perennial plants known for their giant leaves, thriving in moist, nutrient-rich environments. Basic care includes partial shade, ample water, and cool temperatures, with a preference for acidic, organically rich soils. Common challenges comprise of slugs and snails, along with potential crown rot if overwatered or in poorly draining soils. Seasonally, gunnera demands winter protection in colder climates and may require division in spring or early summer for maintenance.
