About Basketgrass

Oplismenus hirtellus 'Variegatus' · also called Basketgrass, Variegated Basket Grass · houseplant

A fast-growing, trailing ornamental grass with narrow leaves striped in white, green, and rose-pink. Excellent in hanging baskets or as ground cover in conservatories. Needs bright indirect light to maintain its vivid variegation, regular watering during growth, and periodic hard cutting back as it becomes straggly after one to two years.

Mature size: 10–20 cm tall (4–8 in), trailing stems to 60 cm (24 in) or more

Watch for — Loss of variegation: Occurs when light levels are too low. Move the plant closer to a bright window. Green reversion — where shoots become fully green — should be cut back to the base to encourage variegated regrowth.

Indoor size vs how big it gets in the wild

Basketgrass 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 10–20 cm tall (4–8 in), trailing stems to 60 cm (24 in) or more. 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

Basketgrass 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: feed with a balanced liquid fertiliser at half strength every 2–3 weeks during the growing season (spring through early autumn). no feeding needed in winter.

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

How to keep basketgrass smaller

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

Trim the longest vines back to the length you want — basketgrass 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 basketgrass 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 basketgrass bigger or faster

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

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
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 basketgrass light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When basketgrass outgrows the room (or the pot)

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

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 basketgrass repotting guide. If you want more of this plant instead of a bigger one, the basketgrass propagation guide turns prunings into new plants.

Basketgrass size — frequently asked questions

How big does basketgrass get?

Basketgrass reaches 10–20 cm tall (4–8 in), trailing stems to 60 cm (24 in) or more 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 basketgrass slow or fast growing?

Basketgrass 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. Basketgrass 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 basketgrass 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.
