Re: Philodendron x evansii/feral Aroids in the U.S.A.

Interestingly, an aroid that has started seeding here
is Alocasia 'Calidora'. The last couple of years I
have been finding some stray seedlings near where we
have this planted. Nothing of an invasive nature.
Also, Monstera deliciosa seedlings have been showing
up, too.

Philodendron x evansii is used infrequently. Most of
the time you see it, it was probably planted in the
late 1960's or 70's. I never see it used anymore. A
few years ago a few SoFL wholesale nurseries had it
again but then disappeared. One was also growing
Philodendron 'Soledad' which is similar. Don't know
the parentage but I think it was developed by Rancho
Soledad Nursery.
