Carole, It's possible that yours might be the one in the Riviera series
Lobelia erinus 'Riviera Blue Eyes' Can you inquire at the nursery where you purchased the plants?
When googling I found this place selling "Blue Eyes Lobelia Seeds", listed as Lobelia erinus but in the description it refers to the name of Riviera Blue Eyes
https://www.2bseeds.com/produc... but The same place also has a listing for Lobelia Palace Blue Eye Seeds but no photo and not much of a description:

If you can't find the exact identity of yours, you can always upload photos to the general entry that covers all
