Calathea Concinna Freddie is known for its beautiful striped green foliage. Calatheas in the wild are found on tropical forest floors, so they can tolerate living in partial shade and make the perfect plant for filling in some of the shadier parts of your plant room! Best kept indoors in a warm spot, with high humidity. Calathea Freddie is a perfect plant for bathrooms, and kitchens. In other rooms, it might require a humidifier, especially in the winter months, when humidity might drop below 50%.
