The Anise Hyssops Database
I don't know if you order from Almost Eden,
https://almostedenplants.com/s... but I like to get their Porterweed (Stachytarpheta). I really like and have had good results with the
Coral Porterweed Stachytarpheta mutabilis
https://almostedenplants.com/s... Red Porterweed (Stachytarpheta mutabilis) I've seen hummers flock to the flowers and even pass up other hummingbird attracting flowers for these flowers. I grow it in a large container tub.
They have other Porterweed varieties

I don't know if you grow it or not, but Coral Honeysuckle (Lonicera sempervirens 'Major Wheeler') is a fantastic hummer plant.
Coral Honeysuckle (Lonicera sempervirens 'Major Wheeler') I keep it deadheaded all season, even into fall.
Of course Red Hot Pokers (aka Torch Lilies aka Kniphofia)
The Torch Lilies Database are great for hummers too.
Sorry it's not long enough, but I hope it helps.
