This seems to be my normal habit - through winter and spring, I am more likely to paint summer and autumn, then through summer I might paint spring. Winter doesn't usually come into it, there is little colour in the garden, the lighting is poor, so the inspiration isn't there.
I think it's because I need time to allow ideas to develop in my head, or maybe I simply procrastinate too much!
Here's another work based on last summer. The evening primrose in my garden put on an amazing display, with the clearest yellow, papery flowers opening every day and giving out a delicious scent that filled the air. Yellow is an incredibly difficult colour in watercolour, avoiding muddy shadows is a challenge, but I am fairly happy with this one.
