The term 'richly-flowered' combines 'richly,' from Old English 'riche,' meaning 'wealthy or abundant,' and 'flowered,' from Old French 'florir,' meaning 'to bloom.'

'Richly-flowered' evolved from the combination of 'richly' and 'flowered,' both of which have roots in Old English and Old French, respectively.

Initially, it meant 'abundantly blooming,' and this meaning has largely remained the same in modern usage.
