Edelweiss Flower Guide: How to Grow and Care for Edelweiss

Edelweiss (Leontopodium nivale) is an alpine plant with star-shaped flowers that belongs to the daisy family (Asteraceae). The leaves and blooms of these mountain flowers—which have white bracts surrounding clumped yellow florets—are covered in woolly hairs that protect the foliage from the elements.

Native to Asia and Europe, these outdoor plants grow best in mountainous areas at high altitudes, such as the Swiss and Austrian Alps. Depending on the habitat, these flowers can grow anywhere between eight and sixteen inches in height and bloom from late spring to early fall.

Edelweiss is a national symbol in Switzerland and holds great cultural significance in Austria, Italy, and Romania.

Plant edelweiss outdoors in the early spring, before the last frost, so that they can undergo cold stratification, the process of introducing seeds to cold and moist conditions to encourage germination. They are most hardy in USDA Hardiness Zones 4–7 and thrive in cool, alpine climates.

Edelweiss is a hardy perennial that’s somewhat tricky to grow unless provided with the ideal environmental conditions. Here is a quick overview of how to grow edelweiss:

1. 1. Cold stratify the seeds. Germination is more likely to happen for these temperamental seeds if you stratify them before planting. To do so, fill a plastic bag with soil and plant your seeds inside. Refrigerate the bag for three weeks before you plan to plant your seeds.
2. 2. Choose a planting site. Edelweiss flowers prefer full sun but can grow in partial shade. Select a spot in your yard or garden that receives full sun or partial shade.
3. 3. Prepare the soil. Edelweiss enjoys gritty, rocky, well-draining soil. They grow well in rock gardens or soil with added pebbles, lime, and sand. Your soil pH should be between 6.5 and 7.5.
4. 4. Sow the seeds. You can sow edelweiss seeds directly into the soil outside by simply sprinkling them on the top layer.
5. 5. Gently water the seeds. The best way to water the seeds is to mist them into the soil. Avoid using the spray from a garden hose, as it can wash away the seeds. Keep the soil and seeds consistently moist for up to six weeks while they germinate. Once they do, you can move them to a spot with more sunlight.

Edelweiss is a low-maintenance plant that can withstand high winds and cold temperatures and is especially resistant to pests and diseases. Here are some tips on caring for this flowering plant:

1. 1. Apply mulch in the fall. Edelweiss prefers snowy growing environments, so if you live in a climate that does not receive snow, a layer of mulch in the fall can help simulate the right conditions for proper growth. Keep the mulch on the plant’s root system all winter until the spring, then remove it.
2. 2. Water the plant sporadically. Edelweiss does not need much water to thrive. The plant is also particularly prone to root rot when subjected to high moisture conditions. Water your plant about once a week during its first year of growth, but it won’t need regular watering after that. Be sure the soil remains permeable, and take care not to overwater your plants.
3. 3. Deadhead the flowers. No pruning is necessary for this alpine flower, but they will self-seed if the flowers remain intact. To keep more control over the growth of your flowers, remove the white flower heads before they go to seed if you want to prevent the plant from spreading. Learn how to deadhead flowers in your garden.
4. 4. Divide the plants. You should dig up and divide your edelweiss every few years to promote continual annual growth. To divide your edelweiss plants, gently dig out your plant’s roots and separate the stems from one another, then replant in a different spot of your yard or garden.
