Hi Aliesh, 'Pillow talk' is a Matthiola incana and is classified as a short-lived perennial, but is usually grown as a biennial now. If will probably die after this year, but may struggle on for a while but will get leggier and leggier each year - that is normal. As far as I know you can only propagate it from seed. If you buy and sow seed now, the plants should flower next year. If you save seed after it flowers this year, it will be 2 years before plants grown from those seeds will flower.
You can try what is suggested above though - nothing to lose!
