germination test

helenh(z6 SW MO)February 23, 2009

I have some coneflower seeds that are from my garden. I put them in a wet paper towel; they did not sprout. I think they may need to be outside in the cold for a while. How do you test germination for seeds that may take a while to germinate? I would not send these seeds to anyone; do others test germination?

In searching a bit I see that coneflowers do indeed need stratification.

do others test germination?
No, I just do my best at letting the seeds or seed pods mature, brown and split if they are the splitting kind of seed pods. I then harvest them and let them dry additionally before packing them for storage in a cool, dry, dark place.

If seeds are properly harvested, they 'should' be fine. It is kind of a crap-shoot though when trading as some members maybe aren't as knowledgeable as others are about the proper maturing and drying of seeds.

The Seed Saving Forum is a great place to learn about harvesting seeds at the appropriate time. Remy is our resident expert there fielding a lot of the questions with good info.

hth...sorry, don't know how to really test them when needing stratification. If they were harvested properly, they should be fine. If you Winter Sow them, you would then later know for sure if they are viable or not.

Define coneflowers - rudbeckia, echinacea, ratibida?

Growing from seed is a grand experiment. Try them and see what happens. I have heard of nothing from these three that would suggest seeds aren't ready when they are loose from the heads.

I have ratabida pinnata and rudbeckia subtomentosa.

Some seeds need to go thru a winter cycle. If you are not ready to plant them yet, just put them in a freezer for 3 weeks and they will be ready come spring. Good luck.
