Tamron SP 90MM f/2.8 AF Macro | | Virginia Dayflower has 3 light blue petals. The third petal is somewhat smaller than the top two petals. Some other Commelina species have darker blue petals, with the third petal being white and notably smaller than the top two. The spathe in Commelina virginica is fused for about a third; that of some other species are fully open. This is a noteworthy attribute for identifying Commelina species. | |

Nikon D7000 | | While looking from the top the leaves may appear to be in a whorl, they are actually spirally arranged. The mud on this plant demonstrates the wet environment in which the plant grows - this plant being in an area frequently flooded after a rain. | | Click on the photo for a larger image

Nikon D7000 | | The leaves are arranged in a spiral, with the sheaths having red hairs on the edges. The plant grows up to about 3 feet high, although in my experience it is usually found to be much shorter. | | Click on the photo for a larger image
