About Russian Tarragon

Artemisia dracunculoides · also called Russian tarragon, false tarragon · herb

Russian tarragon is a vigorous, hardy perennial in the wormwood family, taller and coarser than French tarragon but far easier to grow from seed. Its narrow green leaves carry a mild, slightly bitter anise note that strengthens as plants mature. Sun-loving and drought-tolerant, it spreads readily in poor, free-draining soil where pampered French tarragon would fail.

Mature size: 90-150 cm tall and 45-60 cm wide.

Watch for — Sprawling, floppy stems: Tall growth flops, especially if over-fed or shaded. Site in full sun, keep feeding lean, and cut back hard in late autumn to renew compact growth.

Indoor size vs how big it gets in the wild

Russian Tarragon 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 90-150 cm tall and 45-60 cm wide.. 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.

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

Russian Tarragon 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: undemanding. a single light spring feed of balanced fertiliser or a thin compost mulch is enough. excess nitrogen yields lush growth with diluted, weaker anise flavour.

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

How to keep russian tarragon smaller

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

Divide the clump every year or two — splitting russian tarragon 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 russian tarragon 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 russian tarragon bigger or faster

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

When russian tarragon outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for russian tarragon:

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

Russian Tarragon size — frequently asked questions

How big does russian tarragon get?

Russian Tarragon reaches 90-150 cm tall and 45-60 cm wide. when grown indoors. 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 russian tarragon slow or fast growing?

Russian Tarragon is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Russian Tarragon 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 russian tarragon 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 russian tarragon smaller?

Divide the clump every year or two — splitting russian tarragon 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.
