'abundantly-flowered' originates from the combination of 'abundant' and 'flowered', where 'abundant' meant 'plentiful' and 'flowered' referred to being covered with flowers.

'abundant' changed from the Latin word 'abundare' meaning 'to overflow', and 'flowered' from the Old French 'florir', eventually becoming the modern English word 'flowered'.

Initially, 'abundant' meant 'overflowing', and 'flowered' meant 'covered with flowers', evolving into the current meaning of 'richly adorned with flowers'.
