There were opuntia all over the place, some barely sticking out of the snow, and they were covered in blossoms. Tough plants.

Oh yes, I know, it was the only example of a cactus I could think of that wouldn't die in my climate. Though it probably would not find my soil to it's liking. I wonder if the tiny spines would even bother the cats.

Somewhere I posted the story of how I tried to add it to my herbarium as a young botany student. Tried and failed. They are tough.

Opuntia humifusa has an enormous range, almost into Canada along the Eastern seaboard of North America. It is a low-growing, small plant that spreads horizontally. During winter it dessicates and hugs the ground. With snowmelt it fills with water and stands up a few inches. It blooms in spring.

I know people in the Midwest who plant large patches of it under their windows to discourage burglars.

People grow it here in Ohio, outside. Someone told me that they had been growing it for nearly forty years!

It's tiny thorns are silent but deadly. I have a huge patch of them as well as other more upright cacti here in Indiana. The problem comes in trying to weed them. They do not keep the critters out of our garden so, they problem won't t keep dogs from peeing on your house. If you see them in the act your could try a dog zapper like runners use. Very effective.

I've read that substances with strong scents are enough. Things like all citrine fruits (especially lemmon), alcohol, peper, etc.
I'll buy a bag of lemmons and juice the walls. Now it started to rain already which is great to spread the lemmon through a large area.
