About Lanceolate Anubias

Anubias lanceolata · also called Lance-Leaf Anubias, Lanceolata Anubias · tropical

Anubias lanceolata is a robust, lance-leaved Anubias species producing long, narrow dark-green leaves on a thick rhizome. Slower-growing and shade-tolerant, it is excellent for low-tech aquariums and is virtually indestructible under a wide range of conditions. As an Araceae aroid, it contains calcium oxalates and is classified as toxic to pets.

Mature size: 20–40 cm tall; leaves 10–25 cm long; rhizome spreads slowly over many months

Watch for — Algae on leaves: The most common problem; slow leaf growth means algae has time to colonise. Keep light low, add algae-eating catfish or snails, and ensure good water flow over the leaves.

Indoor size vs how big it gets in the wild

Lanceolate Anubias 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 20–40 cm tall. In the ground with no restriction it is a completely different plant — leaves 10–25 cm long; rhizome spreads slowly over many months — 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

Lanceolate Anubias is a slow grower. Realistically, expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Its feeding profile backs this up: fertilise minimally — anubias is a slow grower and does not require heavy feeding. a dilute liquid fertiliser once every 2–4 weeks is sufficient. excess nutrients in low-light conditions primarily feed algae on the leaves, not the plant.

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

How to keep lanceolate anubias smaller

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

You rarely need to do anything: lanceolate anubias is so slow that it can sit in the same small pot for years.
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 lanceolate anubias bigger or faster

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

Move it to brighter (but not scorching) light — that is the single biggest growth lever for a small plant.
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 lanceolate anubias light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When lanceolate anubias outgrows the room (or the pot)

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

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

Lanceolate Anubias size — frequently asked questions

How big does lanceolate anubias get?

Lanceolate Anubias reaches 20–40 cm tall when grown indoors, and far larger where it grows unrestricted (leaves 10–25 cm long; rhizome spreads slowly over many months). It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Is lanceolate anubias slow or fast growing?

Lanceolate Anubias is a slow grower. Expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Lanceolate Anubias 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 lanceolate anubias take to reach full size?

Roughly many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Light, pot size and feeding move that timeline more than anything else.

How do I keep lanceolate anubias smaller?

You rarely need to do anything: lanceolate anubias is so slow that it can sit in the same small pot for years. 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.
