Bonsai millet

Another "housebound" day.
A "young lady of my acquaintance" bought a fuchsia last year, on bringing it into the shop some bits snapped off, I rooted one, it grew well but a bit "straggly".
This year it got a touch drought-stricken, then when I thought it was dead, regrew.
So it's been topped, see what it's like next year.

The millet (If that's what it is) ... Another of those weird weeds of mine from the bird seed.
