An edelweiss plant, also known as Leontopodium, blooms from late spring to summer and grows to be approximately 30 cm (11.8 inches) tall. Its flowers are white and stellar-shaped, while its foliage is woolly and lance-shaped. Growing an edelweiss outside requires its seeds to be sowed on the surface of the soil during the spring. The plant does best in gritty, loose soil with a pH of 6.5 to 7.5 in part shade. Since edelweiss grow well in snow, the plants require a little more care in areas without snow, according to plant-biology.com.
Protect edelweiss plants from heavy rainfall in snowy climates by making a shelter with a tarp or other waterproof fabric. Place in full sunlight or partial shade.
Surround edelweiss with mulch during the winter in non-snowy climates.
Remove the surrounding mulch from the edelweiss plant at the start of spring.
Divide plants every two years by carefully separating the roots.
Replant divided edelweiss in a similar location to the original planting site. Leave a distance of about 10 to 15 cm (4 to 6 inches) between each plant to allow for proper spread, which will be about 25 cm (10 inches) per plant, according to denverplants.com.
Do not water or prune edelweiss in cold or wet climates. Lightly water in warm to hot climates.
Edelweiss is strictly an outdoor plant that goes into the ground or in a planter. The soil needs to be coarse, neutral to alkaline and without fertiliser.
