Any chance of a photograph, Sipson?

No, sorry. Perhaps if you gave me some names of what they could be I could then look them up.

Many thanks.

Trouble is, your description isn't bringing anything to mind, so 1. is it a shrub or climber 2. is it evergreen 3. is it a summer annual bedding plant 4. How tall and wide is it 5. Curly leaves? more description of the leaves - colour, size, overall shape (oval, round, palmate, etc.)

1. It's a shrub.
3. It's a Summer bedding plant.
4. There are 3 of them. They are about 18" high and 6" across.
5.Larger, bottom leaves are round, smaller ones at the top of the plant are more pointed. They're not really curly, but not serrated. They're like cabbage leaves.

Thanks.

Crinkled leaves then. You don't mean Regal Pelargonium, do you?

No, the flowers are like a Petunia.
Thanks anyway.

Campanula medium, Datura, Lavatera, Phacelia are the only ones I can think of with trumpet shaped flowers and leaves that might be the ones you describe.

About how big (in. or cm) are the leaves and flowers, Sipson?
