Why are my Penstemons leaves mottled?
London, United Kingdom
The new leaves coming through on 2 of my Penstemons (Fujiyama) are looking a bit mottled, I hope you can see from the photo - they are a slightly lighter green in places. I have had them since last July and had no trouble last year. They do have some aphids and greenfly (which I try to wash off). Is this some kind of deficiency? Any help would be much appreciated - Thanks.
