Campbells Camping Part III (What We Found)

When the Campbells go anywhere, there's always collecting involved. This time, we collected:
pine cones (in the hat)
snail shells
a rock in the shape of a gun
a stick in the shape of a gun

Guess which ones Sweet Cheeks collected. Guess which ones Big Ben collected.

And here is what "I" found! I knew this picture was blurry, but I wanted to post it anyway. Amid the harsh winds, desert climate, and dry ground was this beautiful little plant. It was changing colors, and in it I found yellow, orange, red, green, blue and violet. Does anyone know what it is?
