I have succeeded with this plant with only one method, which is to bring it indoors and not let it go fully dormant. It is true you can root it very often by placing in water, when it will strike roots from the nodes. I have had no success with germination from seed, which may well have been infertile. I am a volunteer gardener at Hall Place, Bexley and I am interested in those plants which are marginally hardy. Callistemon citrinus sets seed and germinates sparingly around the mature bushes at Hall Place. Delosperma cooperi thrives, but Lampranthus roseus succumbed to our recent spate of cold weather. Acacia pravissima managed to survive the cold spell too. I agree Pennisetum setaceum ‘Rubrum’ does not overwinter well, not outside or in a polytunnel.
