I have some Purple Coneflower seeds that I want to grow.
Do I need to soak them first?
Please help me!
I winter sow them!! they seem to do better after a cold treatment.
I'm not sure if soaking your seeds will be helpful or not, but I do agree with aquawise regarding the cold treatment. If your seeds are not too old I'm sure some will germinate without any special treatment. However, cold stratification will definitely increase the germination percentage of your Echinacea seed. Winter sowing is fine or you could just put the seeds in a damp paper towel, or a small amount of damp Vermiculite, and keep them in your refrigerator for about a month before sowing them.
+1 Winter sowing works great for purple cone flower.
Mine also seemed to do better when I planted them in the fall but did not sprout until our spring weather kicked in. I have to keep planting just in case they do not come back the following year due to our hot summers. I still have some seeds if you would like a few. Just send me an email.
I have grown them a couple of times from purchased seed. Both the standard purple and the White Swan I didnt soak or cold stratify them. I began them in March, in flats under lights and planted them out in the late spring. They remained fairly small and didnt flower the first year, but came up huge and strong the following year and bloomed like crazy.
