The 'whale tongue agave' was officially described in only 2002. This relatively new species from the far north east corner of Mexico is, without question, one of the most stunning of all. Very chunky perfectly formed rosettes, 180cm across by 1m tall at their maximum after over a decade of very fast growth, are composed of icy-blue, very deeply scalloped leaves. Proven one of the hardiest and easiest in the garden in the UK. Fabuloso!
