I imagine it would want to grow in an arid climate, but I don't know the first thing about botany.

You can buy E. sinica from China quite easily, on eBay last time I checked. It contains ephedrine and has I would say, quite similar effects to amphetamine but shorter lived.

You could also abuse Benzedrex inhalers if those are available where you live. Assuming propylhexedrine isn't scheduled in your country you could import them from the U.S. even if they aren't available in stores where you are. Shit's basically just meth though, but even more recreational and horny ime, so be careful.
