Spider Plant

Chlorophytum comosum,Spider Plant, Spider Ivy, Airplane Plant, Ribbon Plant

The Spider Plant is a very popular, easy-to-grow, herbaceous perennial native to tropical and southern Africa. It is characterized by its long, arching, grass-like foliage, which can be all green or variegated with white or yellow stripes. It is famous for producing long, sturdy stolons (stems) with small, white, star-shaped flowers that eventually develop into tiny plantlets, or "spiderettes" (miniature versions of the mother plant), which hang down like spiders on a web. It is one of the best air-purifying plants and is highly resilient, making it an excellent houseplant.

Care Guide

LIGHT

  • Prefers bright, indirect light to encourage robust growth and abundant "spiderettes."
  • An East or West-facing window is ideal.
  • Tolerant of lower light, but growth will slow, and variegation may fade.
  • Avoid direct, harsh sunlight, which can easily burn the leaves and cause brown scorch marks.

WATER

  • Prefers to be kept evenly moist during the spring and summer growing season.
  • Allow the top inch of soil to dry out between waterings.
  • Overwatering causes the center of the plant to rot and the roots to decline.
  • Underwatering causes the leaves to pale, become brittle, and sometimes develop brown tips.
  • Use distilled, filtered, or rainwater if possible, as it is highly sensitive to the fluoride and mineral salts in tap water, which cause the characteristic brown leaf tips.

SOIL

  • Needs a well-draining, standard indoor potting mix.
  • A blend of potting soil with added perlite or coarse sand is perfect for providing drainage while retaining some moisture.

GROWTH HABIT

  • Ideal conditions: Consistent warmth (65-75F) and average indoor humidity.
  • Growth rate & size: Growth rate is fast. It grows as a clumping rosette, with long leaves reaching 1-2 feet, and stems trailing down several feet.

PROPAGATING

  • Propagates extremely easily from the plantlets ("spiderettes") that form on the long stems.
  • Simply cut the plantlet off the stem and root it in water, moist soil, or even directly in the same pot.
  • New plantlets often root successfully while still attached to the mother plant.
  • Can also be propagated by division of the root clumps when repotting.

PRUNING

  • Pruning is minimal. Remove old, yellowed, or damaged leaves at the base.
  • The long stems that bear the spiderettes can be cut off close to the base if you don't want the plantlets.
  • Cut off any leaves that are severely brown-tipped to maintain a tidy appearance.

REPOTTING

  • Repot when the plant is root-bound, typically every 1-2 years due to its fast growth and bulbous root development.
  • Repot in spring or early summer.
  • The roots are thick and tuberous and can easily crack plastic pots; move up one pot size and refresh the soil.

FERTILIZING

  • Feed regularly during the spring and summer growing season (monthly).
  • Use a balanced liquid houseplant fertilizer diluted to half strength.
  • Avoid over-fertilizing, which is a major cause of salt buildup and subsequent brown leaf tips.
  • Stop fertilizing in the fall and winter.

FLOWERING

  • Produces small, star-shaped, white flowers on the long trailing stems.
  • The flowers are short-lived and quickly replaced by the "spiderettes."

TOXICITY

  • Spider Plants are generally considered non-toxic to humans and pets.

PRO TIPS

  • Brown leaf tips are very common; minimizing them requires pure water (filtered/distilled) and avoiding over-fertilizing.
  • The plant prefers to be slightly pot-bound, which encourages the production of more spiderettes.
  • They look fantastic in hanging baskets where the trailing plantlets can cascade down.

Variability in Care

Variegated Cultivars

Examples: Chlorophytum comosum 'Vittatum' (white stripe down the middle), C. comosum 'Bonnie' (curled leaves)

  • Require brighter indirect light than the all-green types to maintain their sharp variegation.
  • 'Bonnie' has a naturally curled leaf habit that requires no special pruning.

Reverse Variegated Cultivars

Examples: Chlorophytum comosum 'Manderianum' or similar types where the stripe is on the outside.

  • The leaves feature a green center and white/yellow edges.
  • These are sometimes slower-growing than the center-striped types.

All-Green Cultivars

Examples: Chlorophytum comosum 'Hawaiian'

  • The most tolerant of low light conditions due to the high amount of chlorophyll.
  • Will grow quickly under bright indirect light but do not have the ornamental striping.
