Do you like Hollyhocks? We bet that you do not like them as much as Hummingbirds do. After all, you can simply go the refrigerator for dinner, but the little hummingbird finds a whole food source in your garden of hollyhocks. For that matter, you probably have a hummingbird feeder or two, but that’s not same as a big red flower in your yard. Think of it this way: you can have a great dinner but you can get the same food value from a mixture of various health drinks. Which one makes you happy? The hummingbird has evolved over countless centuries of getting food from the center of a plant. If we may get a bit Darwinian here, The feeder might be easier, but the flower completes a natural line.
Hollyhocks are obviously great food plants for hummers. They also look great in your yard. We say: “Go for it!” . However (must there always be a “however”?), hollyhocks are an invasive plant species from Asia and can become an issue if they are controlled. So might say, “They breed like rabbits”. SO, plant them but watch them. You can read more here: How to Grow, Plant, and Care for Hollyhocks| Almanac.com
