That definitely looks like the I carnea. Easy to start .. I use toenail clippers (they are hardcoat seeds) and clip of bits of the coat along one side. You want to clip off enough so that when the seed does germinate the coat will split in two and come off easy so you won't be stuck with your seedlings wearing silly hats. They like full blazing hot sun and lots of food and water.
I grew some out this year, pink and white and they are about 8 feet tall!
