Clematis woes

When we got back from vacation this week the biggest disappointment that faced me was losing my clematis jackmanii flowers.

This is what they looked like before we left.



And a closer view.



This is what they looked like the day we got bak.



Very disappointing. The flowers were supposed to last through September. I don't know if the heat is the culprit or a lack of water. My neighbors said they watered but the flower just wilted and fell off. I'm thinking they were not watered as deeply as they should have been.

I'm hoping more buds will appear. This is the first year I ever got this many flowers from a clematis.
