About Green Lavender

Lavandula viridis · also called Green lavender, Yellow lavender · herb

Green lavender is an evergreen aromatic subshrub native to the dry, nutrient-poor soils of southwest Portugal (Algarve and Baixo Alentejo) and southwest Spain (Huelva and Seville), where it inhabits open scrubland and rocky slopes; it has also been introduced in Madeira and the Azores. It is distinctively unusual among lavenders for its bright green foliage and pale yellow-green flower spikes rather than the typical purple, and it carries a mild, slightly lemony fragrance. It is less cold-hardy than English lavender, requiring a sheltered, very well-drained site and performing best in mild coastal gardens or containers overwintered under glass in colder regions. According to the ASPCA, lavender (Lavandula) is toxic to cats, dogs, and horses.

Mature size: 60–80 cm tall with a spread of 50–70 cm; occasionally reaching 1 m in favourable sheltered conditions.

Indoor size vs how big it gets in the wild

Green Lavender is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect 60–80 cm tall with a spread of 50–70 cm. In the ground with no restriction it is a completely different plant — occasionally reaching 1 m in favourable sheltered conditions. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Growth rate and years to mature

Green Lavender 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: a single light application of a low-nitrogen, high-potassium granular feed in spring is sufficient; over-feeding reduces aromatic oil production and makes plants susceptible to frost damage.

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

How to keep green lavender smaller

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

Prune green lavender annually at the right time for its type — this is the primary, expected way to control its size.
Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
Avoid heavy feeding if you want to limit growth — rich soil and lots of nitrogen drive bigger, faster shrubs.

The keep-it-smaller method, step by step

Prune at the right time. Time the cut to green lavender's type (after flowering for many spring shrubs, late winter for summer-flowering ones) so you do not lose the next display.
Take out the oldest stems. Remove up to a third of the oldest, thickest stems at the base to renew the shrub and contain it.
Shorten the rest. Cut the remaining stems back to an outward-facing bud at the height and width you want.
Restrict the roots. For a permanent size cap, grow it in a large container rather than open ground.

How to grow green lavender bigger or faster

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

Plant it in open ground in good soil — far more vigorous than a container-restricted plant.
Full sun (which it wants) plus an annual mulch and feed gives the strongest growth.
Water well through the first establishment years; a settled root system drives the fastest size gain.

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

When green lavender outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for green lavender:

It shades or crowds neighbouring plants, or blocks a path it used to clear.
Bare, woody, unproductive centres with growth only on the outside — a sign it needs renovation pruning.
It has clearly exceeded the space you allotted and an annual trim no longer holds it.

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

Green Lavender size — frequently asked questions

How big does green lavender get?

Green Lavender reaches 60–80 cm tall with a spread of 50–70 cm when grown indoors, and far larger where it grows unrestricted (occasionally reaching 1 m in favourable sheltered conditions.). Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Is green lavender slow or fast growing?

Green Lavender is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Green Lavender is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets.

How long does green lavender 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.

How do I keep green lavender smaller?

Prune green lavender annually at the right time for its type — this is the primary, expected way to control its size. Remove the oldest, thickest stems at the base each year to keep it open and within bounds. Growing it in a large container rather than open ground naturally restricts the ultimate size.
