Thanks folk. Mary picked the flowers
I did the mixing. I was very pleased with the pot with one Petunia and two Viola - they work very well together. Ive made up a pot of Begonia semperflorens for the pot on the handlebars.
Now I have to think ahead and make up pots to switch in those pots need a rest.
Pleased to say those stabiliser plants seem to work well Phil - hasn't blown over yet
Its in a fairly sheltered spot and shouldn't be hit by a strong crosswind.
