Also called sword ferns, Kimberly queen ferns (Nephrolepis obliterate) make elegant specimen plants, thanks to their straight, upright fronds. These nearly-carefree Australian natives are happy indoors if they’re kept in medium light and given sufficient humidity (if your air is too dry, try running a small humidifier nearby). Outside, they’re hardy in zones 9-11. Indoor gardeners love them because they help purify the air, but you can also enjoy them outdoors in warm weather months.
This Atlanta homeowner used to overwinter these enormous poolside Kimberly Queen ferns on her porch, but eventually decided the time and effort involved was too much. Now she just buys new ferns each year for these massive containers.
