Getting clematis seed's to sprout

I have had some very nice people on here give me some clematis seed''s. After i read on one package i am wondering how hard they will be to grow from seed. So i thought i would ask the expert's LOL. that's not me for sure. What is the best way to get these seed's started? Thank's for all your help.
God Bless,

From Tom Clotheri's site:

"Clematis alpina, campaniflora, flammula, heracleifolia, integrifolia, macropetala, paniculata, potaninii, tangutica, and terniflora , Sow at 20ºC (68ºF), if no germination in 3-4 wks, move to -4 to +4ºC (24-39ºF) for 2-4 wks

Clematis columbiana, Sow outdoors late fall for 91% germ. in May/June. Indoor sowing in light at 20ºC (70ºF) should result in 50% germ. over the period of 2 to 10 weeks.

Clematis fremontii , Sow outdoors immediately after seeds ripen in midsummer. Germination begins in late fall.
