They’re not for everyone but I find that an assortment of sunflowers in my garden is better than Prozac. Visually just so damn happy. Sunflowers (Helianthus annuus ) are also edible at most stages of growth but if you steam or saute those buds you’ll miss out on the flowers. It’s a tough call. Sunflowers have also been used to pull toxins from the soil. In 1994 Chernobyl was the site of floating rafts of sunflowers, the roots dangling in the water to leach out radionuclides cesium 137 and strontium 90. Like an ingredient list in the grocery store if you can’t pronounce it, don’t eat it. It’s not good for you. Thankfully most of us don’t have a nuclear disaster area in our back yard that needs phytoremediation . Me? I’m going to split the seeds with the birds.
