Grown as an annual in my climate, bought as a bedding plant. Took about two months to produce flowers, but they were very beautiful. They only last one day before fading. I deadheaded mine, making sure to remove the seed capsule at the base of the flower so the plant would produce more blooms.

An amazing performer. I sowed seed of 'Belle Blanche' directly outside after last frost in full sun and ended up with a plant that got four and a half feet tall and a couple inches short of ten feet wide.

Pretty plant. Started mine from seeds this spring. Had flowers on it by the end of summer. Also gave me lots of seeds to trade now. I am going to plant her in the ground next spring & see how she like that.

Belle Blanche certainly deserves her name, which means "white beauty" in french. Mine blooms non stop and is incredibly fragrant at night. I have it in a large pot by my bedroom window.
