What do the underside of the leave look like, and what is the texture of the leaf. Also can we have a pic of the whole plant.
Is the stem hairy or prickly ? Both honeysuckle and clematis have smooth stems.
The leaf shape is correct for a clematis armandii - but armadii leaves are thin and soft, also the stems are green, these leaves look thick and rough.
It doesn't look so much a climber, but more of a twinner. Is it grabbing hold of anything to gain height (a climber, ie clematis), or just leaning against something, weaving in and out (a twinner, ie honeysuckle, jasmine)?
PS you've got some champion moss there !
