Several flowers in Genshin Impact bloom at different times based on their nature and location. Here are a couple such examples:

• Windwheel Aster: In Mondstadt, this flower blooms in April, May, and June.
• Cecilia: Throughout the months of March, April, and May, this flower blooms in Mondstadt.
• Silk Flower: In Liyue, this flower blooms in February, March, and April.
• Glaze Lily: In Liyue, this flower blooms in July, August, and September.

It’s worth mentioning that the Genshin Impact in-game calendar does not match to real-world dates, therefore the months indicated above may not correspond to the same months in the actual world. Moreover, certain flowers may only bloom at specific meteorological conditions or times of day.
