Dayflower is a close relative of the Spiderwort. Linneaus named this genus Commelina after the Dutch Commelijn brothers. The two eldest brothers were prominent botanists, represented by the two large blue petals, while the small white petal signifies the third brother, who was somewhat less of an achiever. One of the most charming grasses in Texas is Little Quaking Grass, Briza minor . The spikelets seem to be suspended in the air, quaking in the slightest breeze.
Some people think that the spikelets resemble tiny rattlesnake rattles.
This plant is nice in dried arrangements, if not terribly durable. Soon the parking lot is in sight, bringing an end to another field trip.
