I grew up in Nevada, and I learned a lot about the state symbols of Nevada in 3rd and 7th grade. I even know our state song.
Tangent: nearly everybody I know that grew up in Nevada knows the state song. I can't say the same about anywhere else (in fact, I don't think I've met more than 10 people that know the Utah state song, and I know a lot of people from Utah).
Nevada's state flower is the sagebrush. It's a bush. Not pretty, though it smells lovely, particularly after rain. Certainly not for taking pictures in at any rate. But the Texas blue bonnet is great such things!
Observe: ridiculously cute baby sitting in a green field speckled with indigo colored flowers. Quite picturesque. (these two were taken by the side of the road in Anna, TX after grocery shopping)
Last Saturday we went to a trail in Plano, ostentatiously named "Blue bonnet Trail." I think they had recently mowed it. There were some bluebonnets right at the beginning, but then is was just along stretch of green grass studded with metal electrical pylons. A little dissappointing, but we had fun together, and we took these pictures.
