The chain restaurant says it has created a special doughnut by that name that will be sold for $1 at its Alberta outlets for a limited time.
Tim Hortons says all the money raised will be donated to Red Cross flood relief efforts in southern Alberta.
The rose-shaped disaster doughnut is vanilla dipped, has a yellow Venetian cream centre and is topped with pink, red and white strawberry bark.
It's available beginning Friday.
The wild rose is Alberta's provincial flower.
