Molinia caerulea subsp. caerulea 'Edith Dudszus'
One of the better grasses you will find as this has impeccable manners coupled with tasteful presentation. A dense and self-contained spiky green mound of thin green blades gives rise to dark-stemmed flower spikes which can reach 30" tall and are at their best in late summer to autumn. Came to us via Marchant's in the UK.
