Comment:

A native North American woodland plant, G. maculatum is also quite happy in home gardens. It is very pretty in UV with moderately UV-absorbing petals having slightly lighter shading on their borders perhaps due to some iridescence. There is a central UV-bright star formed by the UV-reflective sepals underlying the petals. The petal veins are UV-dark. The leaf veins are also nicely delineated in UV.

The spring breezes make it difficult to capture the flowers in UV without supplementary UV-flash. They are a bit blurred.

Very interesting. A number of the European representatives have so highly UV-reflective corolla that care is required in exposure not to blow out any detail. These flowers usually appear really "UV white".
