Leontopodium alpinum EDELWEISS (20 seeds)

Edelweiss is a rare, slow-growing perennial plant from the Asteraceae family. This beautiful, mythical alpine plant, standing 20 to 30 cm tall, grows wild in limestone-rich pastures at altitudes between 1,800 and 3,000 meters in the Alpine mountains. It is protected in the wild, and picking it is strictly prohibited in the Hautes-Alpes. It acclimates easily to lowland areas in semi-shaded spots with fresh soil.

Edelweiss seeds from Leontopodium alpinum are black, elongated, and thin, measuring only one millimeter in length. They are harvested 2 to 3 weeks after the start of flowering.

The flowers are small, measuring 3 cm in diameter, star-shaped, and white in color.

This variety possesses silvery, velvety leaves. They form a compact rosette on the mountains. Their oval shape and silky hairs protect the plant from cold winds.

The Myth of the Summits Within Reach

Nicknamed the Edelweiss or Glacier Queen, this is the most legendary plant of our mountain ranges.
In the past, mountaineers picked its felted flower at the peril of their lives as proof of their courage and a symbol of eternal love.
Today, there is no need to climb rocky walls: successfully growing it from collector's seeds is a fascinating project to domesticate this symbol of purity right at home.

A Velvet Armor Against Extremes

Did you know that the famous white and cottony appearance of Edelweiss is actually a natural high-tech armor? This dense down of tiny white hairs protects the plant from intense altitude UV rays, drought, and freezing frosts. By installing it in a stone trough, a terracotta pot, or a sunny rock garden, you bring a unique and ultra-graphic masterpiece of biological adaptation to your outdoor space.

The Ultimate Queen of Rock Gardens

If you are looking for the perfect plant to structure a mineral landscape design or a mountain garden, Edelweiss is the ideal candidate.
Fully hardy, this small perennial only needs a very poor, limestone, and perfectly drained soil (with plenty of gravel) to thrive.
From May to July, it offers its unique starry flowers which, once dried, retain their velvety appearance for years for your floral art projects.

- Germination and Sowing of Seeds:

• The most favorable time to sow edelweiss flowers is during the winter period, from January to March, or by artificially stratifying the culture in the freezer for 2 months. Note that stratification is mandatory.
• Sow the seeds in a small pot of fine potting soil without burying them.
• Gently water the surface of the substrate with a small hand sprayer.
• Place the "Silver Star" culture in a spot with a temperature between 15 and 25°C.
• Germination will generally begin 3 to 5 weeks after following the stratification and sowing procedure.

- Substrate / Soil Type:

The ideal soil type for its cultivation is a very light, highly mineral substrate rich in organic matter, ideally with a slightly acidic pH. The soil must be able to remain fresh.

- Exposure / Light:

The plant grows in a sunny location; the more sun it receives, the more spectacular the flowering will be.

- Temperature / Hardiness:

It does not appreciate heatwaves during the summer at all. It thrives when temperatures oscillate between 5 and 20°C. Its hardiness is excellent; its USDA zone is 4, meaning it can tolerate very cold winter temperatures down to -34°C.

- Watering / Humidity:

It is recommended to water it moderately, about once or twice a week during the hottest summer months. During cooler months, watering can be reduced to once every two weeks.

- Multiplication / Reproduction:

The easiest way to reproduce it remains the sowing of its seeds and the division of its clumps by separating the roots of the plant to obtain new seedlings.
