The plants in the container, remind me somewhat of certain species of Dietes and Sisyrinchium, but in both cases there are visual differences, so I did not identify them as such. Those could also very easily be artificial plants.
The low grass-like plant in the bed, looks like some type of Sedge (Carex) or something similar. The greenish-yellow flowers among the leaves are likely a separate plant ...or possibly even stems stuck in by the photo stylist.
