'white-flowered' originates from the combination of 'white,' meaning 'the color of milk or fresh snow,' and 'flowered,' meaning 'having flowers.'

'White-flowered' combines the Old English 'hwīt' for 'white' and the Middle English 'flour' for 'flower,' eventually forming the modern English term 'white-flowered.'

Initially, it meant 'having flowers of a white color,' and this meaning has largely remained the same in modern usage.
