Morning Glory in Our Place

My wife planted a few Morning Glory in our place.
The flowers are quite elegant and beautiful.

Morning Glory Flower Plant

Our plants flower in purple and blue.

It only flowers in daytime but the flower dies in one day at night.
If the plant is healthy, it flowers everyday.  (different flower everyday)

My wife gave a plant to my mom but it is not doing well.
Canadian weather is too cold for this kind of plant.  It needs to be indoor.
For some reason, my mom does not want to bring it indoor.
(god knows why...)
