Hello, I'm wondering will plants continue to ripen seeds after they have been hit by hard frost?

Thanks Wendey

I was wondering the exact same thing. I know I got hit with a light frost and some of my balloon flower one of the seed pods opened up a few weeks after. A hard frost I do not know, and I can only hope they are still viable since I know they were not fully mature before the frost hit.

If the plant survived the frost then the seed will continue to ripen..... This means the seed will continue to store nutrients & hormones that will enable it to germinate in the spring..... If the plant is frozen then no more sugars/oils & hormones so the seed will not ripen.

Thank you!! I guess I was lucky to get one nice ripe zinnia head from zowie before they froze, but not so lucky with Oklahoma cherry, I dont think I got a single ripe head from it, which is a shame because I havent seen it offered as a single color for years!

Thanks again,
Wendey
