I wonder if anyone can put me straight on which variety of "clematis
cirrhosa" is scented.
Some years ago I was at Wisley on a damp, foggy day, just after
Christmas. Hardly anyone was there; magical!
Going up the rockery steps to the alpine houses I was drawn by a
strong scent. It was a clematis cirrhosa twined around the base of
the big oak tree there at the top. Plain flowers, not spotty, IIRC.
Since then I have sought one for myself. Two I have had have not had
scent, a friend's (Wisley cream) also has no scent. I have consulted
garden centres, books, web sites etc. I did ask at Wisley what theirs
is, but can not now remember what I was told.
One I have in full bloom now is a spotty one, no scent. HELP please.
Can anyone tell me the definitive answer please?
