I bought a junky N. ventricosa from Cosentinos a while ago. I decided i wanted to kill it slowly and horribly. Well, actually, i wanted to see jow how tolerant it was. I planted it in pure african violet mix (the heavily fertilized stuff), i neglected to water it for weeks at a time. I even chopped off the grow point. Well now, the old grow point is rooting, the main stem has 5 NEW PLANTS rising out of it. I hereby deem N. ventricosa indestructible.
