T/N: I like to interpret the song title as "When the flower blooms, forget your worries"
忘忧草 is a type of plant, I'm not a botanist so I don't know which is the correct English name for it (saw google recommending daylilies, though the trans here says forget me nots), I'm just going to follow 9.29Hz World Tour trans, but essentially, it's a flower that's believed to help forget worries.

巷子口 买了花
At the alley’s entrance, I bought flowers
穿过沿街红墙青瓦
I passed the red walls and blue-tiled roofs
夕阳慢慢亲吻着 我的白发
The setting sun slowly kisses my grey hair
推开旧木门 回到家
Pushing open the old wooden door, I return home
把时光 都炖香
Simmer all the time until it becomes fragrant
而你只是笑不说话
And you just smile, saying nothing
一件遗憾的事 就喝一碗汤
For every regret, drink a bowl of soup
庭院深深 秋叶飘落
In the deep courtyard, autumn leaves fall
我们苍老的时候 就回到小时候
When we grow old, we’ll return to our childhood
采青梅用来酿酒你 不许偷着喝
Picking green plums to brew wine, you’re not allowed to sneak a drink
穿朴素的衣裳 牵着那衣袖
Wearing simple clothes, holding onto these sleeves
捡了小猫 名为苍狗
Taking in a kitten, naming it “Cang Gou”
*狗 means dog, 苍狗 is usually used to describe clouds / how life is unpredictable, so it's like a word play here
我们睡去的时候 像孩子无忧愁
When we fall asleep, we’ll be carefree like children
反正也很难上锁这 岁月如小偷
After all, it’s hard to lock away; time is like a thief
若记忆被偷走了 忘了我的爱
If memories are stolen and my love is forgotten
我会说 你好啊
I’ll say, “Hello,”
这是给 你的花
These flowers are for you
花的名字叫忘忧草
Its name is “Forget-me-not.”
它说时光汹涌 如水上烟波
It says time rushes like waves, like mist on water
别走远了 一起回家
Don’t wander too far, let’s go home together
我们苍老的时候 就回到小时候
When we grow old, we’ll return to our childhood
采青梅用来酿酒你 不许偷着喝
Picking green plums to brew wine, you’re not allowed to sneak a drink
穿朴素的衣裳 牵着那衣袖
Wearing simple clothes, holding onto these sleeves
捡了小猫 名为苍狗
Taking in a kitten, naming it “Cang Gou”
*狗 means dog, 苍狗 is usually used to describe clouds / how life is unpredictable, so it's like a word play here
我们睡去的时候 像孩子无忧愁
When we fall asleep, we’ll be worry-free like children
在梦里做个梦 看见你我都老了
Had a dream in a dream, you and I have both turned old
那永恒没骗我 离散也没有
Eternity didn’t lie to me, nor did separation
这份爱只是活在另外时空
This love lives in another time and space
如果 每一声再见 会开启 一个新的空间
If every “goodbye” opens a new space
每做一个梦 是时空 偶尔的重叠
Every dream is an occasional overlap of time and space
你好吗 离开的人啊
How are you, those who’ve left?
请帮我 相爱到剧终
Please help me love until the story’s end
忘忧草 开着花
The forget-me-not is blooming
你在月光下不说话
You stand under the moonlight silently
一件遗憾的事 就喝一碗汤
For every regret, drink a bowl of soup
庭院深深 秋叶飘落
In the deep courtyard, autumn leaves fall
