Fast growing, hardy annual wildflower.

Cornflowers S.O.S.

It's totally normal for Cornflower plant leaves to droop a bit during the day, but they usually bounce back at night. However, if you notice that the Cornflower is still looking sad and droopy, it means the poor thing is losing water quickly, so you gotta give it a good watering. And hey, if the soil is already wet, just let it dry out a bit to avoid any nasty root rot.
