Hiiragi is supposed to be an olive nymph, but she's adorned with hollies... Is what I thought at first. Then I looked up "hiiragi." The translators messed up that panel: the Japanese have two terms for olives in general; "hiiragi" (柊) is Japanese for a specific native olive plant, the holly olive (Osmanthus heterophyllus, also called the "false holly") and is by extension at times used to refer to olives in general, apparently. I'm not sure why Yukimura-sensei decided to use a plant native to the Japanese archipelago here, but let's just chalk it up to Apollo's wandering ways and bask in Hiiragi's cuteness.
