Great to hear you're exploring perennial flowers indoors! A few options to consider are Peace Lilies, African Violets, and Orchids. They can thrive indoors with the right care. Ensure they receive plenty of indirect sunlight and maintain well-draining soil. Regularly check for humidity and water them moderately, allowing the soil to slightly dry out between waterings. Each variety has its specific needs, so it's useful to research each one individually. Happy growing!
