Anybody help with these 3

Please could i have names please and group for the two clematis.
I am guessing the purple is group 3 and the dark purple (just started flowering) is group 2.
Not sure what the green leaves with black 'v' pattern.
Any help would be appreciated

 

The dark purple has 4 leaves and a dark bud in middle

 

There's some varieties of Polygonum that look like that.

 

Thankyou, i found a pic similar on google and it said a knotweed variety , which is bad yes ?

 

Re named Persicaria.
Several named cultivars.
Persicaria virginiana...maybe or named cultivars.
Some are weeds others make very good ornamental garden plants.

It appeared amongst some pansy/petunia seeds i put in a border about 2 months ago. Could it have been in the compost i used ?
Have binned it now.

 

Thankyou.
As a staff member could you sort out my mess in the 30 day photo comp.

 

Any info on the two clematis , which groups ?

 

Have a look around here Lloyd. Taylor's is a very good site for information and their plants are good quality too.

Thankyou , had a look but still not sure. Will prune them next year as group 2 and 3 as flowering times are may and late june.

 

I think the dark purple one looks similar to mine, which is group 3
