as we approach the middle of 水無月, 晩夏 (by 旧暦 reckoning, not the current calendar)
one example of a flower currently coming into season is the なでしこ, sometimes called やまとなでしこ

>なでしこは　いづれともなく　にほへども
>おくれて咲くは　哀れなりけり

>やまがつの　かきほに咲ける　なでしこの
>花の心を　知る人の無き

another name for the flower is 常夏, which is often used as a 掛詞 with 床
>来て見よと　妹が家路に　告げやらむ
>我が独り寝る　とこなつの花
