That cutting that I brought into the house in fall took off, did well, then I killed it by letting it dry out.
The good news is that my plants survived in the ground. I suspect that being in that raised area helped a lot in this very wet year. It's starting to put out new growth at the peripheral nodes that rooted. I'll wait for the weather to be consistently warm and (hopefully) the soil to dry a little, then I'm going to try to sever some of those peripheral rooted parts and try transplanting elsewhere.
It's raining again, and my clay soil will be mud.
