Horsetail is a perennial full of virtues, but often invasive in gardens.
More alluring, the contemporary giant horsetail deserves a special place, in a damp corner or at the edge of a waterhole.
Horsetail comes straight from prehistoric times. It has been found in fossils dating from the Paleozoic Era and at that time it measured over 10 meters. Its virtues have served medicine. Composed of 40% silica, it is widely used for its diuretic, remineralizing and tonic properties.

The feet in the water for the horsetail
Horsetail thrives at the water's edge, in a pond or small pond, or alternatively in the wettest area of the garden if the soil is clayey or sandy. It can also be set up with its feet in the water, in the sun or in partial shade. Or in a pot, provided it is watered frequently.
Like the bamboo, it is quite invasive, so it is better to circumscribe its development perimeter by a stone or brick barrier about fifty centimeters underground. A simpler solution may be to plant it in a large zinc container (bucket, small washing machine, for example) that you bury. It will also be easier to keep the soil moist.
Equisetum japonicum, Japanese horsetail
There are 25 varieties of horsetail. The most common, the one that grows spontaneously in the garden, is Equisetum arvense or horsetail (50cm-80cm) often considered a sore by gardeners.
However, it is a botanical curiosity given its distant origins, and it is also a excellent fungicide, in decoction or manure of horsetail.
She looks like a small conifer, or rather to a branch of a conifer. It is a perennial plant with a scent rhizome. It has no flower, fruit, or seed; it reproduces by its spores.
Much more attractive, Equisetum japonicum, found in garden centers, has a contemporary look, very graphic.
She is beautiful in the garden, but also in pots, at the window or on the balcony where it quickly forms a real curtain of greenery (60 cm to 1 m) that remains green all year round. In spring, on the female stems appear sporangiferous spikes of a pale yellow, the sporangia of which are dispersed by the wind.
