Cultivation details
We have very little information on this species and are not sure how successful it will be in Britain. There are conflicting reports on its hardiness - according to one report it is native to N. France which should make it hardy in Britain[50] whilst another report says that it is only hardy in zone 10 which means that it is not frost tolerant[200]. We would suggest treating it as a frost tender annual and then experimenting with its hardiness. It is likely to require a well-drained dry to moist soil and is also likely to be tolerant of maritime exposure. The plant is very fast growing from seed[50]. A good bee plant[156].
Propagation
Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and plant them out after the last expected frost.

Please don't introduce this weed to new areas. If you do and it grows well, no one will ever again walk barefoot in your corner of the world. Its caltrop-like seeds always have one wicked thorn pointing straight up to impale your foot.

Peter Woods is correct about Tribulus terrestris. It is a highly invasive nuisance weed. I'm surprised this page doesn't give the common names, and I'm also surprised that it claims that there is little information available. The plant is more commonly known as goat's head (from the shape of the burrs) or puncture vine. Around where I live, it's infamous for puncturing bicycle tires. During the summer, I track the burrs in every day and have had to stop using my exercise ball for fear it will be punctured on an undetected burr that grabs onto the carpet. I don't dare walk bardfoot in the house, or with sandals in the front lawn. In farm settings, the burrs make problems for livestock, containg a substance that induces photosensitivy and is harmful to the liver. There are quite a few webpages about various governments' efforts to eradicate this weed. This page mentions its habitat as cultivated beds; it is an opportunistic weed that grows rampant wherever it gains a foothold. It is widespread in the United States, in Australia, and in other areas of the world.

Can anyone present any information which isnt laden with paranoia about the spread of this genus? I am looking to cultivate it, (yes in an area where it grows already in australia) and would like to know how to go about gathering the "fruit" for consumption. Is it wrong to learn all aspects of a species regardless of what potential harm it might cause. A bit of common sense tends to previal where paranoia fails ;)

I recommend the Dr. Max Powers Testosterone Boost which is Tribulus supplements....it will give you the same sex drive boost as any other Tribulus product. How much is that? Hard to say for a 21-year old kid. My testosterone is already peaked. Although I will tell you that I calculated the potency, dosage, and contents of this particular bottle and it's more bang for your buck than any other Tribulus product offered. So if it's straight Tribulus at a great price you are looking for, go with the Dr Max Powers Testosterone Boost. Dr Max products have always done me good (like their stack) and this product is no different.
