About Alice's Sundew

Drosera aliciae · also called Alice's sundew, Alice sundew · houseplant

Alice's sundew is a compact, carnivorous rosette from South Africa's Cape, prized for spoon-shaped leaves studded with glistening, insect-trapping tentacles. It is one of the easiest sundews indoors: give it bright light, mineral-free water by the tray method, and lean peat-sand soil. ASPCA does not list it, so treat as mildly toxic and verify with your vet.

Mature size: Compact: a flat rosette roughly 5-7 cm (2-3 in) across, occasionally to 10 cm in ideal light. Slender flower stalks rise well above the foliage, typically 20-30 cm and up to 40 cm tall.

Watch for — Distorted or stunted new growth: Aphids, mealybugs, or thrips attacking the crown. Remove by hand or use a diluted, carnivorous-safe insecticide — never soap-based products, which sundews tolerate poorly.

Indoor size vs how big it gets in the wild

Alice's Sundew is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect compact: a flat rosette roughly 5-7 cm (2-3 in) across, occasionally to 10 cm in ideal light. slender flower stalks rise well above the foliage, typically 20-30 cm and up to 40 cm tall.. 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.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Growth rate and years to mature

Alice's 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: never add fertiliser to the soil — it will scorch the roots. the plant feeds itself by catching gnats and other small insects on its sticky tentacles. indoors where prey is scarce, you can occasionally offer a tiny insect, rehydrated bloodworm, or fish-food flake to a few leaves, no more than two to four times a month; overfeeding rots the leaves.

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

How to keep alice's sundew smaller

You are not stuck with the maximum size. For alice's sundew specifically, these are the levers, in order of impact:

Prune alice's sundew annually at the right time for its type — this is the primary, expected way to control its size.
Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
Avoid heavy feeding if you want to limit growth — rich soil and lots of nitrogen drive bigger, faster shrubs.

The keep-it-smaller method, step by step

Prune at the right time. Time the cut to alice's sundew's type (after flowering for many spring shrubs, late winter for summer-flowering ones) so you do not lose the next display.
Take out the oldest stems. Remove up to a third of the oldest, thickest stems at the base to renew the shrub and contain it.
Shorten the rest. Cut the remaining stems back to an outward-facing bud at the height and width you want.
Restrict the roots. For a permanent size cap, grow it in a large container rather than open ground.

How to grow alice's sundew bigger or faster

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

Plant it in open ground in good soil — far more vigorous than a container-restricted plant.
Full sun (which it wants) plus an annual mulch and feed gives the strongest growth.
Water well through the first establishment years; a settled root system drives the fastest size gain.

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

When alice's sundew outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for alice's sundew:

It shades or crowds neighbouring plants, or blocks a path it used to clear.
Bare, woody, unproductive centres with growth only on the outside — a sign it needs renovation pruning.
It has clearly exceeded the space you allotted and an annual trim no longer holds it.

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

Alice's Sundew size — frequently asked questions

How big does alice's sundew get?

Alice's Sundew reaches compact: a flat rosette roughly 5-7 cm (2-3 in) across, occasionally to 10 cm in ideal light. slender flower stalks rise well above the foliage, typically 20-30 cm and up to 40 cm tall. when grown indoors. Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Is alice's sundew slow or fast growing?

Alice's Sundew is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Alice's Sundew is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets.

How long does alice's 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.
