About Tenerife Lavender

Lavandula buchii · also called Tenerife lavender, Jagged lavender · herb

Tenerife lavender is an evergreen woody subshrub endemic to the island of Tenerife in the Canary Islands, where it grows on dry, volcanic, rocky slopes and in open scrub. Its deeply pinnate or bipinnate, fern-like grey-green leaves give it a uniquely lacy appearance quite distinct from other lavenders, and it produces tall, branching stems of pale violet-blue flowers over a long season, often near-continuously in mild climates. Being native to a warm subtropical island, it is one of the least frost-hardy lavenders and requires a frost-free or near-frost-free environment to overwinter successfully outdoors in most temperate gardens. According to the ASPCA, lavender (Lavandula) is toxic to cats, dogs, and horses.

Mature size: 60 cm–1 m tall and 90 cm–1.2 m wide in favourable frost-free conditions.

Indoor size vs how big it gets in the wild

Tenerife 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 cm–1 m tall and 90 cm–1.2 m wide in favourable frost-free conditions.. 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

Tenerife 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: feed with a balanced liquid fertiliser once a month during the growing season (spring to early autumn) when grown in containers; in-ground plants on free-draining soil need little fertiliser.

How to keep tenerife lavender smaller

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

Prune tenerife 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 tenerife 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 tenerife lavender bigger or faster

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

When tenerife lavender outgrows the room (or the pot)

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