Tiny Tuesday - Tiny Sunflower

MaryElizaR's Tiny Tuesday challenge this week is on an open theme, except that it should be in mono.

A couple of little self-seeded sunflowers have recently popped up unannounced in the old wheelbarrow which we use as a planter in the garden (see here). The flowerheads are only about 8cm across so that the centres are pretty small - about 1.5cm across so I reckoned they would do for the challenge.
