Several of the Sunflower plants we saw in July were topped only by one single bloom.
(Given the number of buds, though, I suspect that as summer rolled into August and even early September, the ratio of flowers to leaves on these prairie wildflowers changed.)
Prairie Sunflowers grow well in dry sandy soils, reaching heights of up to three feet.
Brown-centred sunflowers, up to about four inches across, provide a cheery splash of colour on the landscape.
