Since the word 'kara' has a meaning of emptiness, sometimes it is restated for good luck as 'utsugi' (or unohana meaning deutzia, mainly used in Kanto region) because of its whiteness or 'kirazu' (written as 雪花菜, mainly used in Kinki region) because it is edible without cutting.
「から」が空に通じるとして、縁起を担いで、白いことからウツギ（うのはな、主に関東地方）、包丁を使わず切らずに食べられるところから雪花菜（きらず、主に近畿地方）などと言いかえることもある。
