Often people use weeds for flowers because they are hardy to that area and therefore easy to keep happy. And many are really pretty. I have several I use in flower beds and some I wish I could but they resent being moved or don't like good soil, preferring stoney, poor soils.

It's Buffalobur (Solanum rostratrum). It's a native plant, but some people consider it to be undesirable.

I agree with KentPfeiffer, Solanum rostratum, a wildflower to some and noxious weed to others:

here, that's considered one of the worst weeds imaginable. The thorns on it are vicious, and extend clear down to the roots. They seed prolifically and will cause great pain to your dogs or cats should they step on one. We use long handled pliers to pull them out because the thorns will pierce leather gloves. Glare

The things you are calling prickles are the same things that Cindi is calling thorns. Regardless of what you call them, they are clearly visible in the picture above.

No need to be sorry. Smiling The botanical differences between prickles, spines, thorns are pretty esoteric and the words are nearly interchangeable in common usage. If I remember right, a botanist would call the pointy things on Buffalobur "spines", but don't quote me on that.

thanks, when someone says thorns my first thought is what roses or lemon trees have.

As that plant gets larger, the spines get larger also. They will be bigger than what you see on roses. Be careful around them. There is a chemical in that plant that causes a long lasting burning pain in humans and animals.
