Personally I think our Clamatis is going to pass away this year
It's just not, 'doing it', if you know what I mean.
Ours (which is the same as Emmz plant) has been looking rather sickly, insofar as it has very few flowers on it, for the past couple of years - although to be fair it is over 20 years old!
I keep thinking that I'll just give it one more year, and so it goes on!
