Many plant-lovers grow spider plants (Chlorophytum comosum) as houseplants for their simple grass-like foliage and cascading baby "spiders." The plants can, however, be grown as perennial in U.S. Department of Agriculture plant hardiness zones 10 and 11. The roots may survive the winter and regrow in the spring in zone 9. Spider plants prefer bright, indirect sunlight and soil that dries slightly between waterings. These photoperiodic plants produce masses of small flowers and spiderettes on arching stems when daylight decreases in the fall. The baby spiders look like miniature spider plants and will grow happily attached to the mother plant, but can be removed and potted to start new plants.
Clip the spiders from the spider plant when they reach the desired size, using clean scissors or garden shears. While some prefer to clip the babies free when they are no more than 2 to 3 inches in size, you can also wait until they are larger.
Position the baby spider in a pot of moist potting soil. Anchor it with a florist pin or a paper clip bent into a U shape to keep the bottom of the baby spider in contact with the soil and prevent it from falling out of the pot.
Place the baby spider plant in bright, indirect light and keep the soil evenly moist until it roots.
Remove the florist pin when the baby spider plant has established a root system. Check for roots by gently tugging on the plant. If it resists your efforts, roots have formed and the pin can be safely removed.
