Last year I bought 3 un-named Clematis, one seems to be Clematis Alpina and
the other 2 are Montana types (thought they were Alba & Rubens) but both
have scented pink flowers, does C. Rubens have scented flowers ?

Whatever it's name is, it smells delicious :-)

Quite a few montanas are scented. Elizabeth, Alexander, Fragrant
Spring, Odorata, rubens (East Malling form)[1], Tetrarose, Entel,
Jacqui, Mayleen, Pink Perfection, Wilsonii, (chocolate) Vera & possibly
others.

[1] Rubens has been propagated from seed for so long (and lost its
purity as a result) or confused with other varieties and mis-named.
East Malling Research Station selected this form as being the closest to
the original introduced in the 1880's. It is sweetly scented.
