Crocosmia aurea. Crocosmia ‘Lucifer’ Bulbs produce the most intense red flowers of any Crocosmia variety. These appear on very long stems that can reach 90-105cm (36-42″) tall. The flowers open sequentially from the bottom to the tip of each stem, and are so rich in nectar that hummingbirds will fight over the claim to sip from them. Over time each bulb planted will fill in an area about 60cm (24″) wide. They look best in clumps for a really bright summer display of flashy red. The perennial plants are hardy in Zones 5 to 9. Ten corms per package.
