Welcome to The Garden Helper's Forum, Luv2garden!
Glad you found us!!!
I have grown just the common Gaillardia
and that's what I do to keep them coming,
is dead head...Then towards the end, when you can
tell the plant
has had enough of blooming,
and it wants to stop, I let the rest of the flowers
go to seed
That way you get a the best of both worlds..flowers
P.S. Just so you know, I'm going to move your post down into the plants
and see if you get some more responses to your question about that specific plant
