Drosera stolonifera · also called Stoloniferous sundew, Leafy sundew · flowering

Drosera stolonifera is a tuberous perennial carnivorous plant endemic to the south-west corner of Western Australia, growing in peaty, water-logged swamp heathland and Jarrah forest around Perth south to Pinjarra. It breaks dormancy in autumn, producing a horizontal stolon that inflates into a basal rosette from which 2–4 semi-erect stems arise; the most critical care fact is respecting its mandatory hot, dry summer dormancy — withhold water once leaves die back. Drosera species are not definitively listed by the ASPCA; treat as mildly-toxic for pets.

Mature size: Stems 10–15 cm tall; basal rosette 4–8 cm across.

Indoor size vs how big it gets in the wild

Stoloniferous Sundew is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect stems 10–15 cm tall. In the ground with no restriction it is a completely different plant — basal rosette 4–8 cm across. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Stoloniferous Sundew 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: offer small live or dried insects onto leaves every 2–3 weeks during active growth; do not apply liquid fertiliser to the soil.

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

How to keep stoloniferous sundew smaller

Good news — stoloniferous sundew barely needs managing. If you do want to keep it tidy:

Divide or remove offsets when the pot looks crowded to keep stoloniferous sundew to a single tidy clump.
Keeping it slightly pot-bound and easing back on feed naturally caps the size.
Pinch or remove the oldest, tiredest leaves so energy goes into a compact, fresh-looking plant.

How to grow stoloniferous sundew bigger or faster

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

It is already in good light; consistent warmth and a balanced feed in spring and summer are the only levers.
A small step up in pot size every couple of years gives the roots a little more room without triggering a size jump.
Feed lightly through the growing season; this plant simply will not race however hard you push it.

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

When stoloniferous sundew outgrows the room (or the pot)

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

Roots circling the bottom or pushing out of the drainage hole — it wants a pot one size up, not a bigger room.
Offsets crowding the surface so the original plant looks squashed.
Honestly, stoloniferous sundew rarely outgrows a room — outgrowing its pot is the only realistic limit.

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

Stoloniferous Sundew size — frequently asked questions

How big does stoloniferous sundew get?

Stoloniferous Sundew reaches stems 10–15 cm tall when grown indoors, and far larger where it grows unrestricted (basal rosette 4–8 cm across.). It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Is stoloniferous sundew slow or fast growing?

Stoloniferous Sundew is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Stoloniferous Sundew is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem.

How long does stoloniferous sundew 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 stoloniferous sundew smaller?

Divide or remove offsets when the pot looks crowded to keep stoloniferous sundew to a single tidy clump. Keeping it slightly pot-bound and easing back on feed naturally caps the size. Pinch or remove the oldest, tiredest leaves so energy goes into a compact, fresh-looking plant.
