Pretreatment: soak seed in water for 24 hours & change water 3 times then store at 40F for 12 weeks (& sow within 6 months of harvest) THEN>>>>>. do not cover seed as light required. soil temp 65-70F & takes 21-28 days to germinate.

Does that really work? Seems like a lot of trouble.....
Would layering work just as well?

Oh good heaven's - that is a lot of work! Would soaking then WSing work?

I've read you have to remove the little tails on them because there is a seed inhibitor in the furry tail. I'd put them in a pot and make a green house tent out of it and set it outside now, keep an eye on it and make sure the soil stays moist and not wet and doesn't dry out.

Check the clematis forum too, I think I saw an interesting thread there on germinating. If I'm not mistaken they said it could take a while to germinate, so don't expect results in a week.

Layering works very well for clematis. Al

I notice you guys live in the US I live In Australia Melbourne. I Have a clemantis which is both in flower and seed at present. When do I collect the seed if they don't fly away first that is, ans when should I plant them? Sory if I sound ignorant but I am new to this. Thanks for the suggestions.

Some Clematis are easy and many are slow-

Just sow them in a pot and keep outside in a shealtered location- they will germinate in the next 3 years.

Some Clematis sprout at warm temps & others take months at alternating temperatures. Some germinate at cool temps.
Some of mine are outside for the second year waitng to shake dormancy. Have fun & try them! Keep the pots in zippered plastic bags. I am always surprised when I see germination after months of nothing!

My Clematis have seed heads on them at them moment. How long after harvest do I wait to plant the seeds?
