About Annual Clary

Salvia viridis · also called Annual Clary, Clary · flowering

Salvia viridis (syn. Salvia horminum) is a fast-growing annual native to the Mediterranean basin, prized for its showy papery bracts in pink, purple, or white rather than its small flowers. It thrives in full sun and poor to moderately fertile, sharply drained soils, making it an excellent choice for gravel gardens and cottage borders. The most important care fact is that rich, moist soil produces lush foliage at the expense of the colourful bracts for which it is grown. The plant is considered mildly toxic to pets due to volatile essential oils present in the Salvia genus.

Mature size: 45–60 cm tall, 20–30 cm spread

Indoor size vs how big it gets in the wild

Annual Clary reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 45–60 cm tall, 20–30 cm spread. 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 sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Annual Clary is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: little to no feeding required; if plants appear pale, a single application of a low-nitrogen liquid feed (e.g. tomato feed) in early summer is sufficient.

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

How to keep annual clary smaller

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

Choose a compact or dwarf variety of annual clary from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.
For some crops, pinching or pruning the growing tips keeps the plant shorter and bushier.
Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow annual clary bigger or faster

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

Full sun, warm soil and steady water are what drive a crop to full size fastest.
Sow at the right time for your zone so it gets the whole season to size up.
Feed appropriately for the crop and never let it check (stall) from drought or cold.

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

When annual clary outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for annual clary:

It sprawls beyond its bed or container before harvest — usually a spacing or support issue.
It flops or needs staking once it hits full height.
Once it has fruited or bolted, it is at its final size for good — the next plant is a new sowing.

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

Annual Clary size — frequently asked questions

How big does annual clary get?

Annual Clary reaches 45–60 cm tall, 20–30 cm spread when grown indoors. It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Is annual clary slow or fast growing?

Annual Clary is a fast grower. Expect a single growing season — it reaches full size in one year, then is done. Annual Clary reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back.

How long does annual clary take to reach full size?

Roughly a single growing season — it reaches full size in one year, then is done. Light, pot size and feeding move that timeline more than anything else.
