About Indian Shot

Canna indica · also called Indian Shot, Canna Lily · tropical

Canna indica is a vigorous tropical perennial native to the Americas, grown for its bold paddle-shaped foliage and bright orange-red flowers. Rhizomes store starch and are edible in some cultures. The ASPCA lists Canna species as non-toxic to dogs and cats, making it a pet-friendly tropical.

Mature size: 1-2 m tall; spreads 45-90 cm per clump

Indoor size vs how big it gets in the wild

Indian Shot 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 1-2 m tall. In the ground with no restriction it is a completely different plant — spreads 45-90 cm per clump — 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

Indian Shot 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: apply a balanced slow-release fertiliser at planting time, then supplement with a high-potassium liquid feed every two weeks during flowering to sustain bloom production through summer.

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

How to keep indian shot smaller

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

Divide the clump every year or two — splitting indian shot 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 indian shot 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 indian shot bigger or faster

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

When indian shot outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for indian shot:

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

Indian Shot size — frequently asked questions

How big does indian shot get?

Indian Shot reaches 1-2 m tall when grown indoors, and far larger where it grows unrestricted (spreads 45-90 cm per clump). 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 indian shot slow or fast growing?

Indian Shot is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Indian Shot 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 indian shot 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.

How do I keep indian shot smaller?

Divide the clump every year or two — splitting indian shot 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 indian shot 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.
