A Flower that shouts "Hello"

This was from my spring garden and it was my favorite flower. It would close at night and reopen like this for several days! I think it was full of the joy in life. I brought it inside due to a storm coming and it lived with us for 3 more days.

 

I have this plant also (picture avatar) its very beautiful

 

I would love to have the plant I chose for my Avatar. What is its botanical name or comon name and where does it grow? Leeta

 

Do you think your plant would grow in the Mid-West United States? Leeta

 

I don't know about the flower, but the foliage in the pic is Lawson's Cypress (Chamaecyparis lawsoniana)
