There are two types of perennial Zea, both of which are like teosinte (Zea
mays ssp mexicana) in female flower morphology: 1) Zea perennis [a
tetraploid]  2) Zea diploperennis [a diploid that can be crossed with Zea
mays ssp mays to produce fertile progeny and backcrossed and selected to
give perennial maize].  However, for obvious reasons, seed companies have
not put much effort into developing useful maize cultivars with the
'perennial' trait.

Because of the short growing season in Northern Europe, I would doubt that
perennial maize would offer any major advantage over annual maize for
producing seed.

A possible source of Zea perennis and/or Zea diploperennis seeds is:
