codonopsis


Hi,
I ordered the seeds for codonopsis (bellflower) with little directins on propagating it.  The package only said:  "start indoors; plant on surface; needs light to germ."  I would like to know how warm/cold the soil temp. needs to be and also how long to allow for germination so I can decide when to sow and have ready for planting...
I'm guessing that since it is a perennial, that it would probably only need 55 to 60 degrees soil to germinate.  I have noticed that annuals need warmer soil.  Am I correct?
Thanks for any help!
Sincerely,
Doris Roberts
