The plant I bought kept breaking at the slightest touch. Bits would even break off from wind. In my experience it is a brittle plant. The last time it broke, it was close to the soil surface. I don't think it will come back. It never got big enough to need staking either. About 6" tall. I think it would have been a very pretty plant to see to maturity.
