Despite the creepy-crawly name, the spider plant is among the most popular and easiest to grow of all hanging or trailing houseplants. While these exceptionally hardy plants will survive in less than perfect conditions, in perfect conditions they are stunning. A mature plant will form tight rosettes of arching leaves with a profusion of hanging plantlets on long stems, up to three feet, somewhat like a bushy green mane. Although there is a pure green variety, the most common variety seen in garden centers in the green-and-white striped 'Variegatum.' Mature plants have small white flowers.
