Early in the spring the Loropetalum chinense var. rubrum 'Fire Dance' (Chinese witch hazel) is flowering. The deep pink flowers are a distinctive colour as many spring shrubs have yellow, white or pale pink blooms. This is a small shrub which can reach 1m in height and width.
during the voice drama watch party livestream, hyuga (rimicha's seiyuu) mentioned the meaning of the sunflowers in the pv and how they may relate to his feelings for kirimi-chan. knowing that (and that hanakotoba seems to have some differences here and there) i decided to go down the rabbit hole
disclaimer: i don't know anything about flowers and guessed for some of them, also most of the sources (listed at the bottom of the post) seem to be wikis of sorts run by either a single person or a small group of people
Rimicha
Sunflowers (ヒマワリ/himawari): As mentioned by Hyuga in the voice drama watch party livestream, they tend to mean "I'm looking at only you" and symbolise "longing".
Strelitzia reginae/bird of paradise flowers (極楽鳥花/gokuraku chouka): Pretty hard to translate, but according to my sources, it carries a negative connotation. The best it can probably be translated as is "a love which you are trying to show yourself bigger and better", according to my sources. (To be clear, what's being translated is 気取った愛, which the machine translation didn't give any clues for what it might mean, and a dictionary was somehow even more confusing.)
Oxalis corniculata/creeping woodsorrel (カタバミ/katabami): I honestly don't know if these are the right flowers, but they're the best guess I have for the small yellow flowers at the base of the bouquet. It seems to symbolise "a shining heart" and mean "to be with you".
Hallritt
Geraniums (ゼラニウム/zeraniumu): I can't tell what type of geraniums they could be, but that doesn't seem to matter in hanakotoba anyways. Red geraniums in particular can represent "friendship", "determination", and "solace", and can carry the meaning "happiness when you're there".
Merold
White roses (白いバラ/shiroi bara): Generally represents "purity" (in the "innocent" sense) and "heartfelt respect". It can have the meaning "I am suitable for you", but it seems it can also mean something like "beauty is your only appeal", which is... interesting.
Pink roses (ピンク色のバラ/pinku iro no bara): Seems to represent meanings like "kind heart", "satisfaction", "promising" (in the sense that one could have a "promising future"), and "elegance". It can also mean "first love" or "to be deeply moved".
White lilies (白いユリ/yuri): Again can represent "innocence", but can also represent "unmarked beauty" or "magnificence". It can also mean "a noble personality". (As a sidenote, I think people generally assume you mean a white lily if you just say "yuri".)
Pink lillies (ピンク色のユリ): Much easier than the above, but funnily enough can mean "insinuations" or "words or behaviour that hints at a deeper meaning", and "vanity".
Asters (アスター/asutaa): White asters tend to represent "change" or "reminiscing", and can also mean "a heart that has faith".
Lupinus (ルピナス/rupinasu): They seem to represent "the (power of) imagination" or "being greedy", which is an interesting difference. They can also mean "always content" or "you are my comfort". The last one's kanji can also mean "peace of mind" or "tranquility", so that's what "comfort" means there.
Calluna vulgaris/heather (カルーナ/karuuna): My best guess for the smaller, darker pink long flowers. This one doesn't have many sources for hanakotoba I can find, so the meanings are probably nonexistant, but a few sites I can find are claiming it can mean "self-reliance", "integrity", and "departure".
Loropetalum chinense (白いトキワマンサク/shiroi tokiwamansaku): The best guess I have at the little white flowers with slim petals. This is another one where I had to go digging for other sources for the hanakotoba, so it might just be all made up. Anyway, it can represent "inspiration" or "mysterious powers", or mean "good luck charm" or "I want to love you" (not entirely sure about the last one).
Gypsophilia/baby breath (かすみソウ/kasumi sou): The very small white flowers (notable at the bottom of the bouquet). This is a later edit because someone I know figured it out. Anyway, white baby breath represent "a calm heart" or "a pure heart".
Fun Fact: Andris personally picked a handful of flowers for the casino
and when i say personally picked, i mean he cozied up to whoever was in charge of arranging the landscaping and floral arrangements for the casino portion of Oleander Gardens and charmed ( verbally and magically ) them into picking the ones he wanted — the ones that were his favorites so he'd have an easier time bonding with them. The flowers that can be found littered around the building are as follows.
Loropetalum chinense is commonly known as loropetalum, Chinese fringe flower and strap flower.
Clade:Eudicots
Order:Saxifragales
Family:Hamamelidaceae
Genus:Loropetalum
The name for the genus comes from the Greek words 'loron' meaning "a strap" and 'petalon' meaning "a petal" in reference to the narrow flower petals.
