2010 Campanula seedlings

[deesen]

In "Dwarf Campanulas" Graham Nicholls doesn't suggest seed needs stratification.

[Peter George]

It needs to be in the winter weather for about 3 months or more. It takes a long time to 'kill' off the germination inhibitors. I've successfully germinated it by placing it outdoors in late November, but when I've potted up seed in March, it's taken another year entirely. Of course you could try GA3.

Thank you for the replies, David and Peter.  I think I have killed a couple of these but have never attempted them from seed.  (Well, fessing up... I have to admit I have Dwarf Campanulas too but was too lazy to look it up.   )  And when I read "(p)ropagation is by seed sown in spring or autumn" in Dwarf Campanulas, I am not sure what should be made of that  - if sown in spring, will it germinate in good time, or will it take months?  Being an optimistic about such things, I think I'd assume or hope for straight-forward germination, but perhaps that statement is meant to cover all the bases... ?    Anyway, I do happen to have GA-3, and will give it a try, since I'm not good at tending apparently-empty pots for more than one season (if it did turn out that way).   Thanks!


P. S.  It's -35 degrees C with wind chill tonight,

I'm going to offer a couple of suggestions that originated from European sites. 
One says this mid European dwarf campanula should be sown in winter, in light, uncovered at 16C - 21C taking 1 - 3 months.  (You are good for sowing in winter, eh? Lori -35C! Hope those temps shoo off NE and do not arrive here in two to three days!)
The other says six weeks of cold stratification, taking approximately one month to germinate in warm.


Sharon......wishing I'd ordered this one!

[Lori S.]

Well, more and more evidence that stratification, starting with a cold period, is indeed the ticket... and no quick results, as you noted, Peter!    Thanks, Sharon.
