These plants can hold a lot of water in their roots..so it can really sustain itself a lot when it is not watered. I found that out when I did a repot last 2012, the container was just too tightly packed..I was amazed how thick those roots were, no wonder they seem so drought tolerant..they are literally water hoarders
From then on, I no longer get worried if I forget to water them..I know they are gorging with water at the root level.
JB: you know what, I think this plant makes its own transformation, depending on the amount of water and light it gets. I have this spider plant which is growing in the shadiest side of my patio..since it is nearer the faucet, I get to water this one a little more frequently than the others on the opposite end...the babies it made had leaves with different styles of variegation: so it made me think, maybe it is not really different types of spider plants..just plants getting different watering/lighting at different phases of their growth.
