So I did some Hana kotoba google’ ing. Here’s a brief (second) look at their meaning below the cut!
Nico
The Agapanthus is known as the “flower of love”. Its meanings include 「the arrival of (romantic) love (恋の訪れ)」, 「love letter（ラブレター）」 and 「intellectual attire/guise （知的な装い）」. It’s said that this last meaning comes from the refreshing and delicate appearance of the pale purple/blue flowers. 440Please respect copyright.ＰＥＮＡＮＡdaxRLXhCyC
