This hummingbird loves the iochroma. Iochroma is a Central or South American plant unrelated to fuschia but similar in appearance. The flowers can be blue, purple, red, yellow, or white. It does quite well in our region.
The iochromas I have are Iochroma coccinea, which I bought as seedlings at Annie’s Annuals in Richmond. Annie’s says it comes from Peru and is “totally tropical,” but the American Horticultural Society says it is from Central America (if anyone can shed light on this please provide info in the comments). Annie’s also says it blooms spring through fall but this year mine stopped blooming sometime in July, possibly as a result of our terrible drought. I thought they might be done for the year, but as this picture taken August 19 (date of this update) shows, they are back now with another blooming season:
Annie’s charges about $10 for a seedling in a four-inch container. But the plant can be propagated from greenwood cuttings in late spring or from semi-ripe cuttings in summer. It should be top-dressed in spring. Pinching young plants will enourage bushiness.
This one is in a container, so it requires water once or twice a week in the dry season. I have another in the ground, which is larger — at least nine feet tall — and requires no maintenance at all.
All parts of the plant are poisonous. But not to hummingbirds.
