Curly lavender (Lavandula dentata)

Lavandula dentata is an easy-to-care shrub

La lavandula dentata it is a perennial subshrub ideal for growing in low maintenance gardens or patios and terraces. It resists drought, and also produces very ornamental purple flowers every year and for several months.

As if that were not enough, and like all the species of the genus, its leaves emit a very pleasant aroma for the human smell ..., but not so much for the insects that cause damage to plants 😉. Know her.

Origin and characteristics

La lavandula dentata, called by the names curly lavender, lavender, toothed lavender, curly lavender, toothed lavender, garlanda or English lavender, it is an evergreen subshrub native to the western Mediterranean region, Macaronesia, and southwestern Asia. In Spain we find it on the eastern and southern coasts of the Iberian Peninsula, in the Balearic Islands from sea level to 400 meters above sea level, and in the Canary Islands.

Grows to a height of 30 to 45cm, with opposite oblong-linear to lanceolate leaves with a size of 4,7-1 by 9,5-0,8mm, grayish green in color. The flowers, which bloom in summer, are purple, up to 1,5cm long.

What are their cares?

If you want to have a copy, we recommend you take care of it as follows:


Has to be outside, in full sun. The more hours of direct light it has, the better it will be.


  • Flower pot: it is not necessary to complicate much: with black peat mixed with perlite in equal parts will be fine. You can put a first layer of previously washed river sand, pumice or similar to improve the drainage even more.
  • the garden: grows on calcareous soils. It adapts very well to those that are also poor in nutrients.

In the garden

From experience I will tell you that it resists drought phenomenally, but on the contrary it fears waterlogging. To give you an idea, where I live (in the driest region of the island of Mallorca, with an annual rainfall of 350mm), if it is in the ground you have to water it from time to time the first year for it to take root, but from the second it stays well on its own.

So, based on this, I advise you to water it about 2 times a week in summer, and every 7 or 10 days the rest of the year. From the second season that I am with you, spread out the risks.


Watering in a pot must be more often than in the garden, since the soil dries much more quickly and the roots cannot grow more than the space in the container allows. Therefore, You should water about 3 times a week during the summer and every 5 or 7 days the rest.

It tolerates calcareous water, but it is preferable to irrigate with rainwater whenever possible.


Manure guano powder is very good for Lavandula dentata

Guano powder.

If you have your lavandula dentata in pot compost it in spring and summer once a month with ecological fertilizersLike guano for instance. You got it liquid here! and powdered by here!.

In the event that you have it in the garden, it is not necessary to pay it although it can be done once a month.


After flowering, the stems must be trimmed, if possible, about 20cm. If it is a very young specimen that has not reached its adult height, you cannot.


It multiplies by seeds and cuttings in spring / summer. Let's see how to proceed in each case:


  1. First, you have to fill a seedling tray (like this) with universal growing medium (get it here!).
  2. Then, it is watered consciously.
  3. A maximum of two seeds are then placed in each socket and covered with a thin layer of substrate.
  4. Then it is sprayed onto the surface.
  5. Finally, the seedbed is placed outside, in full sun.

This way they will germinate in about 2 weeks.


To multiply it by cuttings you have to cut semi-woody pieces without flowers, impregnate the base with homemade rooting agents and then plant them in individual pots, with vermiculite (on sale here!).

Plagues and diseases

It's very tough.


La lavandula dentata resists cold and frost up to -6ºC, and maximum temperatures of up to 40ºC. But it is important to say that in rainy climates it is vulnerable to root rot; that is why it is necessary to make sure that the ground is able to absorb and filter the water quickly.

What uses is it given?


Undoubtedly, it is a very decorative plant. Regardless of whether it is kept in a pot or in the garden, whether it is blooming or not, it is a species that brightens up where it is.


In folk medicine it is used to treat stomach and kidney problems. It has antispasmodic, antiseptic and tonic properties.


  • To obtain perfume.
  • As a pest repellent (also as an anti-mosquito plant).

    Hello, I just bought a lavender in a nursery, however I notice that its leaves are turning brown, yesterday I gave it water and left it in indirect sun and it improved, however today when I took it to the direct sun I saw that its leaves were even put brown on and others dried

      Hello Karla.

      I recommend putting it in semi-shade, and gradually getting it used to the sun. Leave it in direct sun for a while (1-2h) in the early morning and then put it in an area where it is not so exposed. The next day, put it back in a place where it will give it 1-2 hours, and then take it to a more protected place. Repeat this for five more days.

      The following week, instead of leaving it for only two hours in the sun, it will be 3.
      In the third week, 4 hours a day. And in the fourth week, leave it all day.

      If at any time you see that it gets bad, with burns, get used to it more little by little.
