Humans and butterflies alike are drawn to the bold orange blossoms of the Mexican sunflower. The problem is by the middle of August the blooms displayed by this tall plant are often quickly fading. This is unfortunate for those of us that enjoy its stunning beauty and the butterflies and other pollinators that feed at its showy flowers.
With this in mind, if you deadhead the spent blossoms displayed by your Mexican sunflower plants, they will produce a new crop of flowers that will continue to contribute their beauty to our gardens and be a source of nectar for butterflies such as monarchs later in the year when nectar will be less abundant than it is right now.
