I still grow Mexican Sunflowers for the hummingbirds' autumn migration. They absolutely love it. It's great for the Monarch butterflies during migration, too. I had a few dozen monarchs at once last autumn!
Since my 2015 post, I've added a lot more plants specifically to help hummingbirds throughout the entire year.
Before the first species bloom, I hang my oriole feeder, which attracts hummingbirds, too. After the orioles stop showing up, I put it away because my hummingbird-friendly plants start blooming.
Eastern Red Columbine is the first to bloom for the hummers, in May.
As columbine starts to wind down, other species start to take over.
Blue Giant Hyssop
Scarlet Bee Balm
Cardinal Flower
Great Blue Lobelia
I wanted to make my garden more hummingbird-themed, and it's been working nicely. I saw more hummingbirds last year than ever before, and I hope the trend continues as more plants bloom this year and into the future. I continue to collect seeds from those plants and scatter more around each year. I want my yard to be a miniature sanctuary for wildlife.
EDIT: Here's a video I took last year.
