Equisetum hyemale

The Winter Horsetail or Equisetum hyemale is a hardy and evergreen perennial that thrives in moist riverbanks. Its erect stems give it a very graphic appearance that can be used to structure flowerbeds, terraces, balconies, and pathways. Green and upright throughout the year, they are rhythmically marked by black rings regularly spaced along their entire height. This verticality is highly appreciated in any space and enhances the roundness of its neighboring plants. It is a plant that thrives in moderately rich and slightly acidic soil, tolerates frost, and can handle semi-shaded exposure, although it prefers sunlight.

Being fond of damp soil, Winter Horsetail is commonly used around ponds. However, if you have a plot of land that remains very moist for most of the year, you can also make it your own. On the other hand, its rhizomatous roots have a tendency to vigorously colonize its surroundings. Therefore, it can become invasive if not contained. Two solutions are then possible: installing a root barrier or planting it in a pot or container. It actually thrives perfectly well in this type of cultivation, and it will allow you to position it as you wish. Just make sure to water it regularly and keep it in a moist substrate. This way, you can place it near entrances, windows, and play with its slender and contemporary silhouette.

Equisetum hyemale can reach a height of 1 metre (3 feet). Its stems are rigid, straight, and often tightly packed (especially if they are confined to a limited space). Hollow and cylindrical in shape, they can reach a maximum diameter of 1 cm (1in). Considered as "living fossils," these plants have been present on Earth for a very long time. They have retained characteristics that may surprise us today. They reproduce through spores, do not have remarkable flowers, and their leaves reduce to small gray vertical lines outlined by a black ring. Positioned regularly along the stems, they mark segments of 3 to 10 cm (1 to 4in) that grow with the plant. They are topped with a small brown and black ovoid fruit.

Winter Horsetail is highly sought after for its graphic, minimalist, and streamlined ambiance. By multiplying pots in sober colours (gray, black, brown), you will enhance this effect and enjoy its presence throughout the year. On a balcony or in a courtyard, it instantly creates a decor that is energetic. In damp areas, it creates straight lines, curves, and cylindrical flowerbeds, according to your choice of placement. It contrasts elegantly with round, airy, or creeping plants. It is an easy perennial that requires little surveillance and proves to be long-lasting.
