Elaine,
The birds that are here, eat up Agastache seed too, but I don't fault them. Especially the ones that are here during the Winter. You're probably right in that they poop out the seeds somewhere else.
I've grown some Agastache varieties in containers, grow well and some of them have overwintered here.
Agastache rupestris has. Have to look for one of my pics in the container, but here is one that's in the ground, so you can get an idea of what it looks like.
Agastache mexicana Acapulco® Salmon & Pink has been grown in a container, but didn't overwinter.
Here's a pic of what it looks like.
Agastache aurantiaca 'Apricot Sprite'
Grew it in a large container with a few others and it survived a couple of Winters. Don't know if it survived the Winter yet. This is what it looks like.
Agastache 'Apricot Sunrise'
Here's some pics of it in containers taken different years, hardy here, but they didn't overwinter.
Agastache 'Color Spires Pink'
I've grown it in a container and has overwintered a few years so far. I've it in the ground too.
Agastache 'Color Spires Steel Blue'
I've grown it in a container and has overwintered a few years so far. I've it in the ground too.
Agastache 'Firebird'
Grew it in a large container with a few others and it overwintered a couple of years. Don't know if it will survive this Winter yet. This is what it looks like (taken in the shade in the evening).
Agastache 'Raspberry Summer'
I just planted one in a container last year and it grew well, don't know if it's going to overwinter yet. This is what it looks like.
Agastache 'Tangerine Dreams'
Grew it for one season in a container knowing it wouldn't overwinter, but it grew well.
Agastache 'Tutti-frutti'
Grew it in a large container with other Agastaches, grew well and overwintered a couple of years. Don't know if it survived this past Winter. Here's what it looks like.
Make sure the container has excellent drainage. That's what I do.
And Gloria in MI was fighting Japanese beetles bad. She used milky spore (?), and it helped a little. Neem oil is supposed to help as well. Luckily I don't have either problem.. I just have extreme drought & wild weather snaps (80degs in the day, -14 at night...)
