About Tasteless Stonecrop

Sedum sexangulare · also called Tasteless Stonecrop, Six-Angled Stonecrop · houseplant

Sedum sexangulare is a minute, mat-forming stonecrop with tightly spiralled, cylindrical bright-green leaves arranged in six distinct ranks along the stems, resembling tiny watch chains. Cheerful yellow star flowers appear in early summer. Grown as a novelty houseplant or alpine, it needs minimal water, excellent drainage, and as much sun as possible.

Mature size: 2-5 cm tall, spreading 20-40 cm in ideal outdoor conditions; more contained in pots

Indoor size vs how big it gets in the wild

Tasteless Stonecrop 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 more contained in pots. In the ground with no restriction it is a completely different plant — 2-5 cm tall, spreading 20-40 cm in ideal outdoor conditions — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

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

Tasteless Stonecrop is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feed once in spring with a dilute, low-nitrogen cactus fertiliser at quarter strength. no feeding required from autumn through winter when growth is minimal.

How to keep tasteless stonecrop smaller

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

Trim the longest vines back to the length you want — tasteless stonecrop 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.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of tasteless stonecrop 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 tasteless stonecrop bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for tasteless stonecrop 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 tasteless stonecrop light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When tasteless stonecrop outgrows the room (or the pot)

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

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

Tasteless Stonecrop size — frequently asked questions

How big does tasteless stonecrop get?

Tasteless Stonecrop reaches more contained in pots when grown indoors, and far larger where it grows unrestricted (2-5 cm tall, spreading 20-40 cm in ideal outdoor conditions). 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 tasteless stonecrop slow or fast growing?

Tasteless Stonecrop is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Tasteless Stonecrop 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 tasteless stonecrop take to reach full size?

Roughly three to six years to reach mature indoor size, gaining a steady amount each growing season. Light, pot size and feeding move that timeline more than anything else.

How do I keep tasteless stonecrop smaller?

Trim the longest vines back to the length you want — tasteless stonecrop 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.
