This plant was able to survive a Zone 4 winter in a pot one year, and I will see if it will survive another one in its precarious position. I wouldn't be surprised if it could survive a Zone 2 winter (a plant left outside in a pot in winter will endure temperatures equivalent to 2 zones colder than if it were to be planted in the ground).

Very exited about being able to grow this famous plant myself. I started it last year from seed quite easy and now it getting ready to bloom. Local quys (rabbits) didn't notice it yet so hopefully I'll enjoy the first edelweiss flowers in my life.

This beautiful plant can actually grow from 4"-10", and grows well in zones 4-9, Sunset zones 1-9, 14-24. Starfish-like white wooly blooms. Often treated as biennal. enjoys moist soil but not soggy.
Originally from the Swiss Alps, it is the Swiss national flower.
Very cold hardy. Top of plant will die in the winter, the crown below the soil will stay alive. New growth from sprouts following Spring.
Do not cut the green o dead foliage or the spent flower stalks. It is needed to keep for cover of the living portion. To collect seeds, nip off the ripe seedheads, but leave stalks in place. You may snip old foliage when new growth appears in the Spring. Store seeds in an envelope in a cool, dark place. Sow directly in your garden or in little pots. Germinates easily.
Zone 5- This plant has been in my garden for three years- it is demonstrating very slow growth, however continues to bloom annually. Because it is ornamental- very different than the traditional perennials,it remains. It is on the South border of my cottage garden (sheltered by the house on North and East sides), and does not get the protection from cold/snow as the rest of the garden. Other than the occasional Miracle Grow topical, it gets little care.
