The flowers are also smaller than those of garden dahlias, reaching just 8cm (3in) across.
They had some pests on them, aphids and spider mites, discovered only after bringing them home. The insecticide spray I applied on the leaves burned some of them, but now the plants are recovering well.
I was playing around with some raindrops and reflections on the dahlia petals, with not much success on a very cloudy day.
Here is the result, it could be much better with a little bit of sunshine.
