In between Diplarrena moraea and Talinum which one is  known as white iris?
Talinum Talinum is a genus of herbaceous succulent plants in the family Talinaceae (formerly in the family Portulacaceae) whose common names include fameflower and flameflower. Several species bear edible leaves, and "Talinum fruticosum" is widely grown in tropical regions as a leaf vegetable. "Talinum paniculatum" is grown as an ornamental plant.
Diplarrena Diplarrena is a genus of flowering plants in the iris family, Iridaceae. The two species are endemic to Australia. The name is from Greek "diploos" ("double") and "arren" ("male"); plants in the genus have only two functional stamens, while all other Iridaceae have three. The name is often misspelled "Diplarrhena", an error that began with George Bentham's "Flora Australiensis" in 1873.
