Flowers sprung up: start of spring? (5)
I believe the answer is:
roses
'flowers' is the definition.
(rose is a type of flower)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for roses that I've seen before include "Thorny shrubs with bright flowers" , "These flowers in one's cheeks usually denote health" , "Flowers of 15th century war" , "the wars" , "Flowers for watering cans?" .)
