(This is my submission for The Sunday Challenge: Curves :D)

Yesterday Steve and I spent a couple of hours at Riverside Park in Grants Pass, Oregon, and really enjoyed the autumn show going on there. As I was walking around, I noticed the evergreen plants too, and walked over to look at this Holly bush. Suddenly I noticed that many of the leaves had no prickles! How odd!! I found out that this can occur because of drought, young leaves will sometimes not have prickles, and if a Holly shrub is really huge, it may stop producing the prickles because it has enough leaves that the energy necessary to produce the prickles isn't necessary. (I wonder about that answer...)

If you would like to know more about this plant, Wiki has a great page here:
