In my experiment I made planned crosses, gathered the drying seed,, refrigerated the seed in moist paper towel,., potted in January and placed in sunny windows and under lights. I am admittedly obsessive and potted in individual pots as they grew. When I planted them out in May many were several inches tall and some were showing increase. I pushed with water and fertilizer all summer. I got nearly 100 per cent the next spring. It can be done.....Depends on you.
