This name means "beautiful ʻōhiʻa flower" from lehua which is the flower of the ʻōhiʻa tree and nani which means "beauty, glory, splendour."
 
1 Peter 3:3-4 
Your beauty should not come from outward adornment, such as elaborate hairstyles and the wearing of gold jewelry or fine clothes. Rather, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God’s sight.
