I would add that this nectar rich plant is enjoyed by all the nectar-lovers, hummingbirds included (at least in my zone 11 garden). This is not a tidy plant and it spreads out in all directions, becoming a bit lanky, needs staking if exposed to high winds and/or strong rain. It grows wild in the fields and byways of Mexico. Native plants produce red/orange to orange/yellow flowers. They will flower year around and can be planted in the soil year around.

I had bought a packet expecting to grow the beautiful red flowers that I had grown some years ago and was missing this plant badly. When the seeds sprouted and produced buds, I was excited. But when the flower opened, it was Yellow! I was surprised. Only then I came to know, on checking the web, that there was also the yellow variety!
