About Blue Ginger

Dichorisandra thyrsiflora · also called Blue Spiderwort, Brazilian Blue Ginger · houseplant

Blue Ginger is a striking Brazilian rainforest plant in the Commelinaceae family, bearing tall upright stems with glossy spirally arranged leaves and vivid deep blue-violet flower spikes in late summer and autumn. Despite its common name it is not a true ginger. A spectacular but demanding tropical houseplant. Toxicity data is limited; classified mildly-toxic out of caution.

Mature size: 60-150 cm tall indoors

Indoor size vs how big it gets in the wild

Blue Ginger grows on a tree's timeline and scale — indoors it becomes a tall, trunked statement plant rather than a tabletop one. Indoors and in a pot, expect 60-150 cm tall indoors. 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.

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

Blue Ginger 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 every two weeks during spring and summer with a balanced liquid fertiliser at half to full strength. a fertiliser with some potassium will help support flower production. do not feed in winter.

How to keep blue ginger smaller

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

The decisive tool is the secateurs: blue ginger 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 blue ginger 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 blue ginger bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for blue ginger 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 blue ginger light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When blue ginger outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for blue ginger:

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

Blue Ginger size — frequently asked questions

How big does blue ginger get?

Blue Ginger reaches 60-150 cm tall indoors when grown 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 blue ginger slow or fast growing?

Blue Ginger is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Blue Ginger grows on a tree's timeline and scale — indoors it becomes a tall, trunked statement plant rather than a tabletop one.

How long does blue ginger 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.
