I've just noticed in Chiltern's seed catalogue that Briza maxima is
described as a hardy annual (whereas Briza media is perennial) which
means it'll die in the autumn. If you want to keep it going, you must
collect the seed and sow again next year, or let them fall where they
will, but don't cut them off before they're ripe just to tidy up the
plant.
