🔬 Botanical Information — Comparing These Plants

Edelweiss

Scientific Name Leontopodium nivale
Family Asteraceae
Native To Alpine regions of Europe and Asia
Also Known As Edelweiss, Alpine Edelweiss, Glacier Star
Leaves The leaves are lance-shaped, covered in white woolly hairs, and typically 2-5 cm long. The woolly texture helps to conserve moisture and protect the plant from the sun.
Flowers Edelweiss produces small, inconspicuous yellow disc florets clustered in the center of the woolly white bracts. While it can flower outdoors, it rarely flowers indoors due to the difficulty in replicating its natural environment.
