A native of South Africa, Spider Plants are probably one of the most beloved and well-known of all houseplants. Spider plants have long, grass-like green or variegated leaves, and occasional small white flowers. Spider Plants are best known for the small plantlets or spider babies that they form on long stems. These spider babies can be put in soil, and quickly and easily propagated into new plants. Spider plants grow best, and produce babies when slightly pot-bound. But beware that spider plants do not become too root bound, as they grow very fast, and will need to be re-potted frequently.
