About Canary Island Lavender

Lavandula canariensis · also called Canary Island lavender, Canarian lavender · tropical

A vigorous, fast-growing lavender native to the Canary Islands, bearing finely dissected, bright emerald-green ferny foliage very different from the grey leaves of English lavender. It produces slender spikes of pale violet-purple flowers over a long season and thrives in full sun with excellent drainage. Being frost-tender, it should be overwintered under glass in all but the mildest UK or US coastal climates. Lavender is toxic to cats, dogs, and horses according to the ASPCA.

Mature size: 60–120 cm tall and 60–90 cm wide (24–48 in × 24–36 in).

Indoor size vs how big it gets in the wild

Canary Island 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 60–120 cm tall and 60–90 cm wide (24–48 in × 24–36 in).. 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.

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

Canary Island Lavender 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: feed monthly with a balanced liquid fertiliser at half strength from spring through late summer; stop feeding in autumn and winter.

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

How to keep canary island lavender smaller

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

Prune canary island 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 canary island 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 canary island lavender bigger or faster

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

When canary island lavender outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for canary island 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 canary island lavender repotting guide. If you want more of this plant instead of a bigger one, the canary island lavender propagation guide turns prunings into new plants.
