Our local council has been spraying several local colonies of JKW for

AFAIK, in the UK climate JKW does not propagate by seed; so a
colony's survival after weedkilling is not down to seed germination; it
reflects the depth, extent and vigour of its root systems.

Apparently JKW is quite tasty. Next spring when it starts to grow I'm
going to try it.
