Gulf Fritillary butterflies drink nectar from Rayless Sunflower.
This amazing flower rarely grows petals. The bloom is on spikes 24 - 30 inches tall. Leaves primarily grow in a rosette at ground level. The tiny yellow true flowers are in the center of the 'flower'. Like zinnias, true sunflowers have 'bracts' or 'petals' which are actually leaf bracts. The true flower are the tiny yellow flowers in the center of the 'bloom'. In this photo, you can see a Gulf Fritillary drinking nectar from these tiny yellow flowers.
