Allium neriniflorum

A remarkable and distinctive ornamental onion, with long-branching starburst umbels of rose-carmine flowers in early summer.  It was formerly placed in Caloscordum, and it is certainly a departure from other alliums.  Propagated from seed.  Deep 3.5-inch pots.  Zone 5.  Photo: Ray Drew, Alpine Garden Society, http://archive.alpinegardensociety.net/image_files/plantportrait/sizedIMG_101638629.JPG
