I have them both and they are not the same. I can leave the purple heart inground and it comes back in the spring and spreads. It can also be used in hanging baskets. Moses in a cradle is more of a container plant making more of a mound, and must be protected in the winter.

I have the oyster plant, it loves full sun, and spreads like crazy. Mine, is planted at the coast and does not die in the winter. I do not have the purple heart, I do not like its flat look, I think the oyster plant is much prettier, and fuller. I bought mine in Florida, where it is called the oyster plant, in Texas it is called Moses in the boat. Barbra,

I'm glad to know it's different and it stands up. Thanks!
