I have more than a few Peruvianus specimens. Some come from Berkley Botanical Garden, A few from the infamous KK, a Pervuainus "fastest", and my favorite, my Short Spined Monstrose Peruvianus. The "Fastest" is a close second, as it lives up to its name and grew about a foot and a 1/2 over the last couple of months of summer upon its arrival here. It's really hard to give recommendations on specimens though, you never know how much difference you'll get in things that are supposedly the same or carry the same name :/.
Only a few find the way, some don't recognize it when they do - some... don't ever want to.- Cheshire Cat
Every adventure requires a first step. Trite, but true, even here.
