I bought this under the name 'Blue Steel', which it most certainly is not. It most closely resembles some of the Mexican species that have become popular of late, such as E.venustum, but the leaves are much less deeply cut. It doesn't quite match any of the better-known South Americans either so I'm stumped.
That said it's a handsome bromeliad-like evergreen with small violet inflorescences. I shelter it from the worst of the winter weather here and grow it on a very well-drained soil in full sun, where it has developed into a clump about 2ft across and about the same in height (at flowering time).
