Five families of geophytes

[Robert_Parks]

Dierama reynoldsii holding down the delicate end of summer flowers
Amaryllis belladonna...or more likely A. belladonna with some Brunsvigia
Oxalis tuberosa (Oca), one of the rare handsome flowers from a plant that specializes in vegetative propagation
Amorphophallus henryi with amazing iridescence...and the scent of fresh horse poop
Bomarea sp., none of the local birds understand what is going on here.
