African daisies- often seen as a marker of resilience and the beauty of adaptability in Africa
Purple- noble cheerfulness and dignity
Yellow- optimism and sunny disposition
Daisies native to Japan don’t actually come in these colors but in hanakotoba they symbolize purity, new beginnings, innocence, beauty and faith
Buttercups symbolize joy, radiance, youthful beauty, and cheerfulness. In hanakotoba they represent childhood memories, innocence, and truth.
Pansies in general represent remembrance, free-thinking, and merriment and Shakespeare connects them to a love in idleness (perhaps a connection to Mizuki wanting stagnation) In Hanakotoba they represent caring and thoughtfulness.
Yellow ones specifically mean happiness and positive thoughts while in Hanakotoba they represent remembrance. Meanwhile the white ones represent innocence and remembrance while symbolizing thoughts of love in Hanakotoba.
They're a bit difficult to see but the solitary white and yellow flowers seem to be lilies which generally symbolize purity, devotion, and rebirth in the west and purity and refined beauty in Japan. White lillies represent innocence and purity and are common wedding flowers. In hanakotoba they also represent majesty. Yellow lilies symbolize friendship and joy in the west and, interestingly enough gaiety and falsehood in hanakotoba.
Upon closer inspection, that blue flower at the left there looks like it might be a flax flower which generally represent everlasting strength, domesticity, and simplicity. To get more specific the blue ones symbolize delight. I couldn't find a meaning in hanakotoba.
Oh, and just for fun, raspberry flowers represent kindness and virtue. Of course, the fruit is what's actually pictured but still. I also couldn't find a hanakotoba meaning for these.
Strawberries symbolize love and passion. They were also associated with temptation in medieval Europe. In hanakotoba, they represent esteem, love, and perfect goodness.
Overall, Mizuki has a bunch flowers associated with joy, friendship, and positivity with a couple of mildly concerning ones sprinkled about. Our girl is healing and moving forward! A few snags here and there. She still feels as though happiness is something she cannot have, but Rome wasn't built in a day!
(Special thanks to @mimikyuno and @biocrafthero for helping me identify these flowers and also sharing hanakotoba resources with me! I could not have done this without them)
