I really like this

It reveals, however, a drawback of this plant. Notice how thin the offset is compared to the main stem.
More than likely, the offset stem will get thinner and thinner. Over time, the plant will look more like a weed than a decorative plant. This happens particularly in low light, which is how this plant is most often located.
I think of Lucky Bamboo as a plant decoration somewhere between a cut flower and an indoor plant. With that said, you buy a new Lucky Bamboo when it gets too ratty looking.
One solution that I favor is to buy Dracaena sanderiana tip cuttings and root them. Or, you could buy a Dracaena sanderiana plant and take tip cuttings from it. Who would know that it isn't a "real" Lucky Bamboo plant? Just kidding. They're all Dracaena sanderiana no matter whet the retailer calls them.

This plant was made from stem cuttings bought from a floral booth at a farmers market. They're growing in expanded clay pebbles (hydroculture). I don't think they are readily available on the retail market but it's worth checking out.
Note that none of the Lucky Bamboo plants in these photos are tip cuttings. These plants were all propagated from stem sections.
