What shall I do with my clematis seedlings?
in Plants
I have a dozen seedling clematis, grown this spring from an unknown parent plant, possibly montana, though I was hoping they were C.tangutica. They have got away from me... I repotted them a couple of months ago, but they've taken off. They blow over in the wind and try to climb neighbouring plants in the cold frame.
Clearly the pots are too small, but is it too late to repot them now? If so, should I cut them back, and by how much? They are clearly different in leaf colour, and to some extent in vigour, so I'd like to grow them all on in pots until they flower, before deciding which to keep in the garden.
Thanks in advance...

Since 2019 I've lived in east Clare, in the west of Ireland.

They've grown very quickly!
I live in west central Scotland - not where that photo is...
If you were able to cut them right back in the following spring, I'd reckon it would be fine to take them quite far. To about a foot or so?
The one on the left looks quite montana-like, but I'd agree - the other one looks different.

How have things been this year for the nursery? It's been a difficult year for so many people and businesses.

I germinated them in plastic bags containing the seeds on pieces of damp kitchen paper, in my dark but warm shed. C.alpina didn't germinate though, so I've potted a few seeds up and put them outside to see what happens.
Not sure it would be the best time though.
I've got some 'accidental' cuttings, as I was doing a bit of hacking and slashing recently on the Group 2 that it's with. Not sure if they'll work either, but it was worth a go.
Now that Richard says it - I can see the montana shape of the foliage on the other plant. It looked different higher up, but I think it's the angle.
I really hope they all take and grow well for you.
