'abundant-flowering' originates from the combination of 'abundant' and 'flowering', where 'abundant' means 'plentiful' and 'flowering' refers to the process of producing flowers.

'Abundant-flowering' combines the Middle English 'abundant' from Latin 'abundans' and 'flowering' from Old English 'flowrian'.

Initially, it meant 'producing many flowers', and this meaning has largely remained the same in modern usage.
