These flowers are easy to grow from seed. Beautiful color, the purple is hard to find if you buy from a nursery. Lasted all summer and I live were it is very hot and dry. Will buy and grow these every year.
My first time (2017) to try flower seeds inside with a heat pad for sprouting. The seedlings were small and fragile, but once they hit the dirt outside they did just fine. Loving the color added to my existing shades.
