Calendula arvensis

You have probably never heard of a plant with this name, Calendula arvensis. However, when I tell you the properties and uses of it, it sure sounds like you and you know what it is. Its common name is margarita. It is a plant known practically worldwide. It comes from Eurasia and, in most cases, it is planted as a medicinal plant rather than a decoration plant. It can be found widely distributed throughout the world.

In this article we are going to tell you about the characteristics, uses and properties of Calendula arvensis.

Main features

This plant is annual and comes from Eurasia. In good conditions it is capable of reaching about 30 cm in height. It uses anthophiles to be able to pollinate its yellow flowers and they are endowed with monoecious reproductive units. Like jasmine, Calendula arvensis is fairly easy for everyone to recognize. Its flowers are quite well known. They have lobed leaves that are not separated by folios. There is only one leaf per node, along the entire stem.

The flowers of this plant are annual, although it depends a lot on the habitat where they are found. They have a tubular circle in the center. The rays form a strap around it. The most striking feature is probably that the flowers are tubular and hermaphroditic. It has a single ring of flowers that surrounds the rest of the central florets of the disk that we have mentioned above.

They are intense yellow in color and that makes it very striking when you see a group of these flowers in a field. On some occasions, depending on the environmental conditions and the variety in question that we are treating, these flowers can be orange in color. In addition, they can have between twenty and fifty petals that offer many options when removing the daisy.

Surely when they were little they played “loves me, doesn’t love me” with margaritas. This could be done due to the large number of petals that the plant has. To the As with the Bouvardia Ternifolia, the Calendula arvensis is considered by most horticulturists as one of the easiest plants to grow. When gardeners know they have to plant daisies in a garden, they know it’s easy. This is because it has an incredible ability to tolerate most soils.

These plants are best grown in temperate climates, and are planted in the spring to achieve their flowering during the summer and much of the fall. This way we get that we not only have plants for medicinal purposes, but they can also give us some aesthetics.

Calendula arvensis cultivation

This plant is quite easy to grow. Let’s talk about your needs. It is not at all demanding in terms of the type of soil where it can be developed. It can grow in soils with neutral, alkaline and acidic pH. If the rest of the environmental conditions are suitable, it will be able to develop in nutrient-poor soils. The underground part is capable of growing vigorously in both sandy, loam and clay texture. However, these soils must retain some moisture. With this information you can deduce the frequency of irrigation that this plant needs. Most commonly, enough watering is needed to cover some moisture in the soil on a consistent basis.

To adapt the irrigation according to the time of year, it is interesting to observe what type of soil we have, the solar exposure throughout the year and the temperatures that it does. In this way, we can know the frequency of irrigation you need. One important thing to keep in mind is that this plant does not tolerate waterlogging. In other words, whatever the type of soil where we have it planted, it must have good drainage. If to maintain humidity we must water something more, it is necessary to see if the water accumulates, since it could cause the roots to rot.

As for sun exposure, we can see that it is quite demanding. We can only place them in direct sunlight to keep them healthy. They do not tolerate the shade. It could live well in semi-shade, but if you can, it is always preferable to have them in full sun. The good thing about Calendula arvensis is that it is able to withstand more extreme environmental conditions such as frost.

You are lucky with this plant as it is considered one of the most resistant to pests and diseases. We will not have problems with this type of situation.

C alendula arvensis toxicity

Now we will move on to the negative aspects of this plant. Although it has beneficial properties for human health, it also has a certain degree of toxicity. This toxicity can be harmful to some people.

Among the uses of the daisy are many. You can make infusions with its leaves and flowers, oils, creams, etc. It is suggested that caution be exercised with the use of this plant since, due to its toxicity, it can cause some adverse reactions in certain groups of people.

There are situations in which the consumption of Calendula arvensis is not recommended at all:

Suspicion of pregnancy

If you suspect that you are pregnant or certainly are, this product may not be recommended. The harmlessness to the fetus is not proven by science. We say this because this plant is often used for menstrual cramps, believing that it has properties that stimulate the uterus in women. For this reason it is not convenient to use it if you are pregnant or have the slightest suspicion.


The same goes for these kinds of situations. People with allergies can get dermatitis just by touching them.


When we are taking a medicine prescribed by the doctor, we should not take any infusion with this plant. This can cause the alteration or inhibit the proper functioning of the medicines.

I hope that with this information you can learn more about the properties of Calendula arvensis.
