Your pink butterfly bush looks fine in the morning but by early afternoon it looks droopy and wilted?

It must be the heat and maby also not enough water - the best thing would be if you moved it to a spot with a bit more shade - if that is not possible you can do damage-control with 3-4 big soda bottles filled with water and put up-side-down in the soil - then the plant can suck water when it wants and you dont have to water alot all the time during the day hope the answer was helpful - luise:)
