Kind of alpine avalanche? (8)
I believe the answer is:
snowdrop
'avalanche?' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for snowdrop that I've seen before include "Winter bloomer" , "Bulbous plant that flowers in early spring" , "White-flowered plant (Galanthus nivalis)" , "Late winter flower" , "Spring bloom" .)
