From Memory Alpha, the free Star Trek reference.

Edosian orchids are herbaceous plants which produce beautiful flowers.

While he served as a gardener at the Cardassian embassy on Romulus, Elim Garak specialized in Edosian orchids. He would later mention to Odo that the orchids also happen to be extremely poisonous. (DS9: "Broken Link")

The name of the plant is believed to be a homage to the race of the animated character Arex who was a Edosian according to studio materials.
