It is known as agrimony or St. William’s wort, and is a typical plant of the Iberian area. To the point that it grows spontaneously and is accustomed to large periods of drought.
However, in this article we will offer information on both the medicinal properties assigned to agrimony and the shape of its cultivation and its agronomic characteristics.
It is scientifically known as Eupatorian agrimony. Although it is not very complicated to pronounce, it is also known as agrimony (dry) or St. William’s wort.
It is a perennial type plant of the family Rosaceae with a characteristic yellow flower, which loves to live with species as Iberian as holm oaks and oaks. We can not get an idea of the large number of species that includes the family of rosacea, since apart from this plant are also included species as different as almond, peach, apple, roses, etc.)
Its name, specifically the part of eupatoria, comes from an ancient scholar of medicinal plants, the King Mithridates eupator. Of this man there are many stories and legends, such as that he had a wide range of poisons on hand and that little by little he was getting used to them for fear of being poisoned.
We have no doubt that he experienced many properties of medicinal plants, and one of them was the agrimony plant. It is attributed at that time its powerful antihemorrhagic effect.
Hence, in some specific areas it is known, apart from agrimony, as «wound grass» or «blood loss«.
As it is a plant rich in tannins, it is formerly used for its oils and its laxative capacity, since in high concentrations these tannins became toxic.
Agrimony was formerly used to treat liver conditions, and at that time the roots of the plant and stems, highly enriched in vegetable oils, were selected.
How Eupatorian agrimony it has the ability to self-pollinate and is well adapted to the Mediterranean environment, it is common to see it in many places, with spontaneous growth.

Agrimony cultivation (Eupatorian agrimony)
Not very established cultivation except at the pharmaceutical or commercial level. Eupatorian agrimony it is a plant that we can find it wild if we know how to look for it. On the internet there is even information on the points of greatest growth or where it has been found, registered by lovers of medicinal or aromatic plants.
However, we cannot doubt the apparent ornamental considerations that can be extracted from St. William’s wort and can create confusion between species. Interestingly, this name is not widely used today, rather the term agrimony.
By the growing conditions and its climatological adaptation and to different types of soil, can be used in the design of xerophytic or rockery gardens.
Soil characteristics and humidity
Eupatorian agrimony in all types of soils and circumstances. In many bibliography it is mentioned that clay soils are positive for their development, but it has also been seen to grow in those of sandy or stony type.
Agrimony takes place in environments of Mediterranean atmosphere, with hot climates, long periods of light and dry. It is not only developed in Spain, far from it, since it is widely cultivated in warm areas of Europe, North Africa and America.
Irrigation and fertilizer
The network of its roots and its exploratory capacity, make the plant Eupatorian agrimony as an all-terrain species that is able to adapt to Mediterranean climates with water shortages and long periods of drought.

It appreciates maintenance irrigations especially in warm times, where there are no moisture resources in the soil.
Pests and diseases associated with agrimony
Currently, no specific types of pests and diseases that act against this plant have been documented or studied. Except rare aphid attacks (very unselective species) and because they had nothing closer.
This is closely related to its high content in tannins, astringent and bitter taste, which does not make it attractive for the installation of a pest or disease.
Ornamental calendar of agrimony
The flowering occurs in the summer months (June to August in the northern hemisphere), formed by these clusters of small yellow flowers. These flowers are used for various properties, as they were collected in the book that we tell later (Bach flowers).
The seed collection, if it is also required to take advantage of its high oil content as a medicinal remedy, it will be later, in the final months of summer.
At the ornamental level, it can be planted in gardens of low water conditions, such as xerophytes or coastal environments. If they depose in number, they can form a tapestry of yellow flowers in summer, which can be combined with other types of species and medicinal plants, such as Santolina.
Active ingredients analysed
The main active ingredients collected in the laboratory and extracted from different parts of theeupatoria grimonia are as follows:
- Phenolic compounds (malic acid, stearic acid, citric acid, etc.)
- Salicylic acid
- Ellagic tannins (agrimonolide) between 4-10% and catechic tannins.
- Other types of essential oils
