The plant I need identifying is the large fountain grass-like plant.
It is sharing the M&S arrangement with an orchid.
The leaves are quite firm and spring directly out of (no stem) what appears
to be a bulb/corm half buried in the compost.
Photos here show the arrangement and a close-up of the bulb/corm below.
