About Stoloniferous Sundew
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.
Preferred mix: Sandy peat or pure horticultural sand
Watch for — Tuber rot during dormancy: The most common cause of plant death; once the plant dies back allow the soil to dry fully and store in a warm, dry spot — any residual moisture around the tuber in summer causes fungal rot.
Why stoloniferous sundew needs this mix
Stoloniferous Sundew flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for stoloniferous sundew: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons stoloniferous sundew struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives stoloniferous sundew weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving stoloniferous sundew in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for stoloniferous sundew?
Most flowering plants, including stoloniferous sundew, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for stoloniferous sundew in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for stoloniferous sundew covers the timing and technique step by step.
