A very distinctive Mexican species with linear leaves and tightly scaled winter buds.
Photographed at the Palmengarten in Frankfurt in 1982, looking as good as I have ever seen it.
This group showed an impressive variability in flower, presumably they had been raised from seed, instead

The tightly packed winter rosettes were completely undamage by temperatures of -5degC in the greenhouse.
Even young plants just forming on leaf cuttings were unaffected.
