Well, really many plants that succeeded have become biomass producers, but one that I liked was the mint I planted on my greywater canal in 2018. Last summer in 2020 it was a nice stand of the stuff, much more than I could use, so before it could flower I cut it all and used it to mulch garden vegetables. It was a nice orderly mulch, nicely locked together so the wind wouldn't take it away (important in my location). Recently in May 2021, I was surprised to see the stand that I cut last summer doesn't seem to have sent up any shoots at all this year, although of course there's still mint popping up here and there nearby.
