That would be my thought about these "Bizarre sources of firewood",
they're just very green and high in water content. When dried down to
the 10% or so suitable for a wood burner there won't be much left of
them though they might make reasonable kindling.

Actually, the base of the magenta spreen was as woody as (say) hazel,
and a significant length as woody as willow or poplar. That's what
triggered me into asking. Brassica are a bit less woody, I agree.
