Cactus, anyone?

My layout is southwestern and I wouldn’t mind a few cacti here and there (HO scale). Any ideas on where to get or make some?

I use a piece of thin cardstock, draw the pods on it with a pencil ,and then cut the cacti pods out with a hobby knife … i then glue the pods in a random pattern to create a plant and paint them green, let it dry, and glue it to the layout…Chuck

Plastruct, Keil Line and Scenic Express all make cactii. Do a search on the Walthers website for 18 listings of 2 different species.
