I've had this guy propogating in a jar for a few months and all of his roots are darkish (why is that by the way?) but most importantly, THIS ONE IS BONE WHITE! Why is it bone white while the others are dark? (The plant and roots feel healthy. EPSECIALLY the white one is strong as hell. Very firm bone white root. This guy has only ever grown in water. All of the roots have never touched dirt. So why are the roots dark (not mushy) except for this bone white root? It's fascinating to me, but I must know - why is it so white???
