Paris quadrifolia HERB-PARIS (10 seeds)

Herb-Paris, also known as True Lover's Knot or Paris quadrifolia in Latin, is a plant from the Liliaceae family. It is a small, four-leaved, perennial herbaceous variety that measures 20 cm in height. It is also sometimes called "One-berry" or "Wolf's-strangle" because of its toxicity. It is a forest species found in cool undergrowth on limestone soils. Its dispersal capabilities are very limited because it reproduces mainly by rhizomes, which grow only a few centimeters annually. The dispersal speed of its seeds is estimated at only 20 to 30 cm per year. Furthermore, it is found less and less frequently, making it increasingly rare. Its foliage is unique in its arrangement. A single central stem bears a whorl composed of four leaves.

These leaves are sessile, oval-shaped, with visible veins. They are arranged horizontally in a cross at the top of the stem, creating a matte green leafy platform that highlights the single central flower.

The flower is solitary, standing on a short stalk (peduncle) at the center of the leaf whorl. With a very architectural appearance and a yellowish-green color, it does not possess colored petals to attract insects.

Its fruit is a single, globular, and fleshy berry that sits at the center of the leaves after flowering. At maturity, it takes on a bluish-black hue, covered with a waxy bloom that gives it a velvety look. Although it visually resembles a large blueberry, this berry is toxic to humans.

Herb-Paris seeds are brown and possess a fleshy coating called an aril, which facilitates their dispersal.

- Properties:

It is distinguished by its almost perfect geometric silhouette. It is a rare plant with a mystical allure, ideal for botanical gardens or gardens dedicated to collectors' plants. It is cultivated strictly as an undergrowth plant; it can be placed in shaded beds or under the cover of large trees. It can also serve as an aesthetic groundcover.

It is a historical medicinal plant. Formerly used in ancient phytotherapy for its antispasmodic virtues, it is nowadays cultivated strictly for ornament due to its high toxicity. Do not consume.

- Germination and Sowing:

• The most favorable period for sowing Herb-Paris is from the beginning of March until the end of April.
• Stratify the seeds for 2 to 4 weeks before starting germination.
• Prepare a tray with a substrate rich in organic matter.
• Bury the seeds under a few millimeters of substrate.
• Water the crop gently.
• Finally, place the tray at a temperature of 15 to 25°C, keeping the substrate constantly moist.
• Germination can take 1 to 3 months after planting.

- Soil Type / Substrate:

The Four-leaved Herb-Paris requires typical forest soil: rich in humus, cool, and deep. It thrives particularly well in limestone or alkaline soils, although it tolerates slight acidity. The substrate must remain loose and never compact to allow the rhizome to develop without hindrance.

- Exposure / Sunlight:

It is a plant for shade or partial shade. In its natural environment, it grows under the canopy of deciduous trees. It fears direct sunlight, which quickly burns its fragile foliage. Filtered light under trees is essential for its survival.

- Temperature / Hardiness:

Paris quadrifolia is an extremely hardy plant, capable of withstanding temperatures dropping below -20°C. It is perfectly adapted to the temperate and cold climates of Europe and Asia. Its cycle follows the seasons: the aerial part disappears completely in winter, while the rhizome enters dormancy underground to protect itself from frost.

- Watering / Water Needs:

The need for moisture is constant. The soil must remain cool throughout the growing season. It absolutely cannot tolerate prolonged drought, which causes the plant to wither prematurely. A mulch of dead leaves is often necessary to maintain stable humidity at the soil level.

- Multiplication:

Propagation is done by seed or naturally through the slow growth of its creeping rhizome, which eventually forms small colonies.

- Pests / Diseases:

Few parasites attack this plant due to its toxicity. However, slugs and snails can be fond of young shoots in the spring. Regarding diseases, an excess of sun combined with a lack of water can lead to marginal drying of the leaves.
