Gosh, lets take these one at a time. Hilary, Crassula ovata and Iris germanica are both correct.
Joanna, no Cerinthe I'm afraid and the 'tassel hyacinth' is a Bellevalia trifoliata..
In the yellows, not a yellow oleander but an Eremophila maculata "Aurea". No to alamanda, yes to Medicago arborea and the orchid, also to the Thunbergia alata.
The whites, no pelargoniums but yes to Lantana camara, Viburnum tinus, Zantedeschia aethiopica and the rose is Rosa banksiae "Flore Pleno".
