About Madagascar Jasmine

Stephanotis floribunda · also called Madagascar jasmine, Bridal wreath · flowering

Madagascar jasmine (Stephanotis floribunda) is a twining evergreen vine prized for intensely fragrant, waxy white trumpet flowers. Give it bright, filtered light, consistently moist soil in summer, warmth above 13C and high humidity. Avoid moving it while in bud. The ASPCA lists it as non-toxic to dogs, cats and horses.

Mature size: Up to about 3m (10ft) tall and wide when trained on a support; readily kept smaller with pruning indoors.

Indoor size vs how big it gets in the wild

Madagascar Jasmine is a tree at heart. Indoors a pot and your ceiling keep it to up to about 3m (10ft) tall and wide when trained on a support, but in the ground it is a different scale of plant entirely (readily kept smaller with pruning indoors.). Indoors and in a pot, expect up to about 3m (10ft) tall and wide when trained on a support. In the ground with no restriction it is a completely different plant — readily kept smaller with pruning indoors. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Madagascar Jasmine is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed fortnightly from spring to early autumn (roughly april to october) with a high-potassium liquid feed such as a diluted tomato fertiliser to support flowering. stop feeding in winter while growth slows.

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

How to keep madagascar jasmine smaller

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

The decisive tool is the secateurs: madagascar jasmine can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want madagascar jasmine and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow madagascar jasmine bigger or faster

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

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

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

When madagascar jasmine outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for madagascar jasmine:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

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

Madagascar Jasmine size — frequently asked questions

How big does madagascar jasmine get?

Madagascar Jasmine reaches up to about 3m (10ft) tall and wide when trained on a support when grown indoors, and far larger where it grows unrestricted (readily kept smaller with pruning indoors.). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is madagascar jasmine slow or fast growing?

Madagascar Jasmine is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Madagascar Jasmine is a tree at heart. Indoors a pot and your ceiling keep it to up to about 3m (10ft) tall and wide when trained on a support, but in the ground it is a different scale of plant entirely (readily kept smaller with pruning indoors.).

How long does madagascar jasmine take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
