fall sowing larkspur in zone 5
I have some beds empty and I'd like to grow several flowers for cutting next year. I have read about fall sowing annuals such as larkspur, nigella, bachelor buttons and agrostemma in zone 5. Anyone done it and have advice?
From online searches I get conflicting info. Some people say to expect them to sprout and then over winter (beneath all the snow!) and they will resume growing very early spring. Other people say the seed needs the cold treatment to sprout and grow well the following spring. I direct sowed some seed as an experiment about 10 days ago, but no sprouts so far. Not sure if it is still too early...but then worried maybe it is actually too late!
I tried direct sowing some larkspur in the spring this year, but it never got very large. Nigella did fine though.
Eventually I'd love to have a few hundred feet of larkspur for cutting and drying, so finding the right time to sow them would mean a lot to me.
Also looking for info on planting sweet peas in the spring.
