Julie you gardens are lovely. I like the jumbled look the bezt. Maybe it's because thats how mine are to.
I have had almost no luck this year with my morning glorys.
What I have pretty good luck with is
snap dragons,
marigolds
Canna lilys
Nastriums
And a mixture of others that will bloom next year such as foxgloves, bellflowers, columbine, rose campion.
I also have unnamed ones.
