HI Temptryst
When I talked with a women that sells a lot of aquarium plants, she told me that the plants would do fine in sand.I have heard it so before too, but suspiciously assume they just want to sell their plants.

I have a sand bottom in one of my tanks and love live plants as well and do keep them. Some plants need to adhere to something like a rock, or
driftwood, as they need to attach their feelers, those I doubt would do good in sand. Anything with a strong root system may work. But dont forget to account for your lighting system before buying your plants as that would be real important to know.
