高嶺 (たかね) consist of two characters ‘高(たか)’ meaning ‘high’ and 嶺(ね) meaning ‘the top of a mountain’, and 花(はな) means ‘flower’. The kanji character ‘嶺’ used in 高嶺 is usually read ‘みね’, and there are two other kanji characters that have the same meaning and reading: ‘峯’ and ‘峰’. There are scarcely any differences between them, and 峰 is probably the most common kanji character in modern Japanese.
