About Forked Aichryson

Aichryson dichotomum · also called Forked Aichryson, Tree of Love · houseplant

A biennial or short-lived perennial succulent endemic to the Canary Islands (Tenerife, Gran Canaria, La Palma, Hierro, Gomera), growing 20–40 cm tall with dichotomously branching stems covered in soft hairs. Bright yellow star flowers appear in spring and summer. Grows in laurel-forest shade; prefers cool, bright conditions indoors with a distinct winter rest.

Mature size: 20–40 cm (8–16 in) tall; occasionally to 80 cm (32 in) in ideal conditions

Watch for — Aphids on new growth: Soft, hairy new shoots attract aphids, particularly in spring. Check the growing tips regularly and treat with insecticidal soap or a forceful water rinse. Avoid systemic insecticides if possible, as the plant is naturally short-lived.

Indoor size vs how big it gets in the wild

Forked Aichryson stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect 20–40 cm (8–16 in) tall. In the ground with no restriction it is a completely different plant — occasionally to 80 cm (32 in) in ideal conditions — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Forked Aichryson 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 monthly with a balanced liquid fertiliser at half strength during active growth (spring–summer). move to a cooler, slightly less bright location in winter and cease feeding entirely.

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

How to keep forked aichryson smaller

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

Divide the clump every year or two — splitting forked aichryson is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide forked aichryson out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow forked aichryson bigger or faster

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

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

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

When forked aichryson outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for forked aichryson:

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

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

Forked Aichryson size — frequently asked questions

How big does forked aichryson get?

Forked Aichryson reaches 20–40 cm (8–16 in) tall when grown indoors, and far larger where it grows unrestricted (occasionally to 80 cm (32 in) in ideal conditions). Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Is forked aichryson slow or fast growing?

Forked Aichryson is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Forked Aichryson stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward.

How long does forked aichryson 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 forked aichryson smaller?

Divide the clump every year or two — splitting forked aichryson is the main way to control its spread and refresh it. Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump. Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

How can I make forked aichryson grow bigger or faster?

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger. Good light plus regular feeding maximises offset and runner production. Leave plantlets and offsets attached and feed through the growing season for the fastest spread.
