Hello - I wonder could you tell me what's happening to my delphiniums? They seemed to be growing well but have suddenly started to wilt. The delphinium plant beside it, which looks very healthy, is covered with bugs (aphids?) but I can't see any on the plant that's wilting. As you can probably guess, I don't know an awful lot about this gardening lark but I'm really trying to get my garden sorted!

Aphids are a common issue with Lupines and will cause a downward twisting growth.
