These are my favourite amusements of yesterday visit Food Garden. Scorzonera hispanica, black salsify, black oyster plant, serpent root, viper's herb and many other names. Aster family. South America, Alpine garden. Sisyrinchium palmifolium, Palm-leaf Yellow-Eyed Grass, Iris family. Looks like they are still not in bloom? Oxalis valdiviensis, I think this plant is new at UBC garden.
