About Spider plant

Chlorophytum comosum · also called airplane plant, ribbon plant · houseplant

Spider plant is a beginner-favourite trailer with arching grassy leaves and dangling pups that root readily. It tolerates a wide range of household conditions but is famously fussy about fluoride in tap water. Pet-safe by ASPCA standards.

Chlorophytum comosum is an evergreen perennial of the asparagus family native to tropical and southern Africa, ranging from West Africa and Ethiopia to South Africa, and naturalised widely elsewhere.

Plantlet production is photoperiodic: arching scapes form baby plantlets when the mother plant gets short days and long uninterrupted nights (under ~12 hours light) for about three weeks, making propagation by these plantlets trivial. It is listed non-toxic to cats and dogs by the ASPCA.

Mature size: 30-45 cm tall, plantlets trailing up to 60 cm

Indoor size vs how big it gets in the wild

Spider plant does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect 30-45 cm tall, plantlets trailing up to 60 cm. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Spider plant is a fast grower. Realistically, expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Its feeding profile backs this up: half-strength balanced liquid feed every 4-6 weeks during the growing season.

Want this turned into the right next pot at the right moment? The pot size calculator and the spider plant repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast spider plant grows.

How to keep spider plant smaller

You are not stuck with the maximum size. For spider plant specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — spider plant takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
Expect to tidy it every few weeks in summer — this is a fast vine that will sprawl if left.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of spider plant should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow spider plant bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for spider plant the accelerators are:

More (indirect) light dramatically lengthens the vines and enlarges the leaves.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The spider plant light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When spider plant outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for spider plant:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the spider plant repotting guide. If you want more of this plant instead of a bigger one, the spider plant propagation guide turns prunings into new plants.

Spider plant size — frequently asked questions

How big does spider plant get?

Spider plant reaches 30-45 cm tall, plantlets trailing up to 60 cm when grown indoors. Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Is spider plant slow or fast growing?

Spider plant is a fast grower. Expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Spider plant does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims.

How long does spider plant take to reach full size?

Roughly one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Light, pot size and feeding move that timeline more than anything else.
