Plant rejected a kind of strike after one fellow sacked (7)
I believe the answer is:
fuchsia
'plant' is the definition.
(type of shrub)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fuchsia that I've seen before include "Ornamental flowering plant - reddish-purple" , "Tropical shrub with drooping flowers" , "One blooming" , "Flower; colour" , "Vivid purplish-red" .)
