Cast Iron Plant -
The cast-iron plant (Aspidistra elatior) has earned its reputation as a hard-to-kill houseplant, along with being a beautiful outdoor foliage plant within its growing zones. This plant can survive lots of neglect and growing conditions that will kill many other plants, such as low light conditions. It has arching, lance-shaped, deep green, glossy leaves that can reach around 2 feet long and 4 inches wide. When grown outdoors, it sometimes produces insignificant cream and purple flowers near the base of the plant, but the blossoms usually do not appear when the plant is grown indoors. The cast-iron plant has a fairly slow growth rate, and spring is generally the best time to plant it.
