I've grown a clematis from seed I germinated about 4 years ago but unfortunately it hasn't yet flowered and I've lost the name. It's quite a rampant grower and I've grown it on the north side of my house as well as on the south side in front of a Rosa 'John Cabot' along with a Clematis jackmanii in partial shade. Would anyone have any idea what this clematis might be? And secondly, how to possibly induce it to bloom? The C. jackmanii blooms quite prolifically and is treated the same as the unknown Clematis. I took the photos yesterday.

I meant to include the additional photo but mistakenly didn't.
-
The description of a "rampant grower" along with the three-part toothed leaves put me in mind of Clematis virginiana, virgin's bower.
-
Yes Lori, I think that's it.
I did a bit of research on the net and I'm pretty sure that your suggestion is correct. All I need to do now is determine how to make it bloom. It should be pretty easy since it is a native. However, since C. virginiana is dioecious does anyone have any photos that distinguish the two different flower types?
-
Leaves do look like my virginiana. Grew it from seed last year and it bloomed this year, located in a full sun area. Sorry I don't have pics though.
-
Rob,
The attached site may help to explain the (sometimes, apparently) dioecious nature of C. virginiana:

(Male flowers are staminate, that is, lacking pistils, while female flowers are pistilate, or lacking stamens. The site says that both male and female flowers may occur on the same plant, as well.)

While we are on the subject of clematis, does anyone think this looks like C. hirsutissima?

Hi Fermi
Your clematis looks like one I have grown from seed collected near lake Baikal, which is very much like C. integrifolia. I have attached a photo of Clematis hirsutissima & the one grown from seed ex Lake Baikal.

Fermi,
Here's a couple of pics of my first integrifolia michelle/fascination seedling's flower.
Bonus is the flower is scented, are yours?
Mike, your Lake Baikal seedling is gorgeous, my first LB seedling to flower was really ratty looking, sepals going every which way.
-
Lori,
The other interesting thing said was that regardless of whether the flowers are staminate or pistilate they look pretty much the same - I'm assuming from a distance. Since mine hasn't flowered yet I'll try putting a couple inches of compost around the roots in the spring and see if that does it.
-
Rob, for looking at flower details, I find a 10x hand lens (which I happen to have for geology anyway) is indispensible... given the current state of my eyesight, at any rate!
-
I agree with the others Fermi, yours looks like C. integrifolia. I've had C. hirsutissima for years, a couple of plants which send up many stems but nary a flower in all that time.
-
Thanks, Mike, Helen and Lesley!
I had planted out two clematis into this bed and obviously it's the C. integrifolia which has survived. ;D
cheers

Lesley, I have had a C. Scottii in the garden for 3 years and no sign of a flower :'(
It comes up in Spring, looks tatty most of summer and then starts to grow again in Autumn.
-
Well my scottii 'Rosea' does flower and the poor thing's still in a pot where it has lived for at least 10 years, waiting to have a place in the garden. Perhaps the answer is treat 'em rough. :-\
-
Lesley, how big is the pot and where is it situated?
How much sun does it get?
Do you have any pics?
-
No pics I'm afraid Helen as it's always been a straggling thing, lolling around without support. The pot is a 2 litre plastc, and it's with hundreds of others in full sun. It's from this area I'm getting the stuff to plant my new bit along the nursery border. I have to water these pots almost daily from now to April as in the sun they dry out so quickly. It's half under gum trees which drop their b..... leaves all over everything and the water doesn't penetrate those.
-
Lesley, I would be so happy to see a few gum leaves, just to smell them would be nice.
I bet your plants grow like the clappers once they get freed from jail.
