The Dragon's Mouth is a very grateful flower

The Antirrhinum, whose scientific name is Antirrhinus major, is a biennial plant native to the Mediterranean, specifically from Morocco, Portugal and southern France to eastern Turkey and Syria. It is popularly known as Dragon's Mouth, Lion's Mouth, Antirrino, Calf, Bunnies, Dragonaria, Little Dragonflies, Zapaticos de la Virgen, Flor de Sapo or Dragones.

It is characterized by reach a height of between 1,5 and 2 meters, with a somewhat woody base. It develops erect stems from which sprout opposite and linear leaves 1-7cm long by 1-25mm wide, with entire margins.

What are the care you need?

Antirrhinum majus is very easy to care for

If you want to get a copy, we recommend providing the following care:


So that your antirrhinum can be fine, it needs to be placed outside, in a sunny exposure.


  • Flower pot: you can use the universal substrate that they sell already prepared in any nursery or here! mixed with 30% perlite (you can buy it here!).
  • Garden: it is indifferent, but it will root better - and therefore will have a better development - if the land is fertile and has good drainage.


The frequency of irrigation will depend on the season of the year in which we are as well as the climate in the area. But to have a guide you should know that you have to water more often during the months when it does not rain much or not at all, and less in the rainy season.

But ... how often? So so, about 3-4 times a week in summer and a little less the rest of the year. If you have it planted in a pot with a plate underneath, remember, especially in autumn and winter, to remove any excess water ten minutes after watering, otherwise its root system would rot.


Throughout the growing season, that is, from the beginning of spring to the end of summer, it is highly recommended to fertilize it with a liquid fertilizer, like this one here!, following the indications specified on the product packaging. In the case of having it in the garden, you can add egg and / or banana shells, tea bags, and / or vegetables that are no longer edible.

Planting or transplanting time

You can plant your antirrhinum in the garden or move it to a larger pot in spring, as soon as the risk of frost has passed.


Aphids can affect wallflowers

It can be affected by the following pests:

  • Aphids: they are very small insects that measure about 0,5cm in color green, yellow or brown. They perch on the most tender leaves and flowers, from where they feed. To control them, the ideal is to place yellow sticky traps (you can buy them here!) near the plant.
  • Mealybugs: They are cottony or limpet-like parasites that feed on the sap of the leaves. They are fought with specific insecticides, such as this one from here!.
  • Mites: they attack the flowers, causing the petals to have a poor development. They are fought with acaricides, like this one from here!.


It can be affected by the following:

  • Rust: It is a fungus that is manifested by the appearance of small brownish pustules on the leaves, stems and flowers. It is fought with Bordeaux mixture.
  • Botrytis: it is a fungus that is manifested by the appearance of a grayish powder on the leaves. It is fought with fungicides such as zineb.
  • Mildew: it is a fungus that causes the appearance of yellow spots that turn brown on the underside of the leaves. Over time, in humid environments, white mold forms. It is fought with fungicides.


The Antirrhunum is a biennial flower

The wallflower multiplies by seeds in spring-summer. For it, proceed as follows:

  1. The first thing to do is fill a pot of about 10,5cm in diameter with universal growing substrate.
  2. Afterwards, a maximum of 3 seeds are placed in the container, as far apart as they can be, and covered with a thin layer of substrate.
  3. Finally, it is watered and the pot is placed outside, in full sun or in semi-shade.

The first will germinate in about 10-14 days.


Withstands cold and frost up to -4ºC without being damaged, but you have to think that it is biennial: after flowering and producing seeds, the plant will wither even if the weather is warm.
