The spider plant (Chlorophytum comosum) is a popular and low-maintenance houseplant known for its arching, striped foliage and its ability to produce small plantlets, or “spiderettes,” on long stems.. Originally from coastal regions of southern and tropical Africa, it is highly valued for its hardiness, air-purifying qualities, and ease of propagation.
Features and varieties
- Appearance:The leaves are long, slender, and can be solid green or variegated with white or cream stripes. The foliage grows in a rosette and develops thick, fleshy roots that store water.
- Flowers and “spiderettes”:Mature plants produce small, inconspicuous white flowers on long, thin stems called stolons. After the flowers fade, new plantlets form in their place. These babies are easy to root and share.
- Common varieties include:
- ‘Vittatum’:A very popularvariety with mid-green leaves featuring a broad white stripe down the center.
- ‘Variegatum’:Has darker green leaves with white margins.
- ‘Bonnie’:Features green leaves with a creamy white center, but with a unique curly texture.
Care instructions
- Light:Provide bright, indirect sunlight. Direct sun can scorch the leaves and cause brown tips. The variegation may fade in low-light conditions.
- Water:Water when the top inch of soil feels dry. The plant is tolerant of irregular watering, thanks to its water-storing tuberous roots, but avoid soggy soil to prevent root rot. For best results, consider using distilled or rainwater, as spider plants can be sensitive to chemicals like fluoride and chlorine in tap water, which can cause brown leaf tips.
- Soil and fertilizer:A well-draining, loose potting mix is ideal. Feed the plant once a month during the spring and summer growing season with a balanced, all-purpose fertilizer. Avoid over-fertilizing, as this can also cause leaf tips to turn brown.
- Temperature and humidity:Spider plants prefer average household temperatures between 6575F (1824C) and moderate-to-high humidity. Keep them away from cold drafts and heating/cooling vents.
Propagation
Spider plants are famous for how easily they can be propagated. You can use three main methods:
In water:Snip a spiderette from its stem and place it in a glass of distilled water. Change the water regularly. Once the roots are a few inches long, transplant the baby plant into soil.
- In soil (attached to mother):Place a pot with soil next to the mother plant and plant a spiderette in it while it is still attached to its stem. Once the plantlet has rooted, snip the stem to separate it.
- By division:For large, mature plants, you can divide the root ball into sections, each with its own leaves and roots. Replant each section into its own pot.
Benefits and safety
- Air purification:Spider plants are known to help filter common household toxins from the air, such as formaldehyde, xylene, and carbon monoxide.
- Pet-friendly:They are non-toxic to cats and dogs. However, they contain mild chemical compounds that can cause an upset stomach if consumed in large quantities, so it’s best to keep them out of reach of curious pets.
- Stress reduction:Like other houseplants, their presence has been shown to reduce stress and anxiety in people.
