I bought a few poinsettias last Thanksgiving at Lowe's. It was a black friday sale and I think I paid 99 cents for each one.
They were small and I kept them inside all winter. When it warmed up I put one in a pot and moved it outside. The other one I kept in the house and later planted it.
The one in the pot was watered by sprinklers , the one planted in the sand ( soil is awful around here) depended on the rain.
I wanted the one in the pot to bloom. I moved it in and out of the garage and one day I saw the one in the back had red flowers! That was it for babying the one in the pot, it was now on it's own.
I'll pull the one out of the soil before we get a frost and put it in a pot. I don't want it to die, it's proven to be a survivor.
