Notes:
Tropiflora grew a bunch of these from seeds from an unidentified herbarium specimen, "Puya species cayata Ecuador HL 1-08". Harry Luther said that this is a high altitude plant and shouldn't do well in Florida.

However, it seems to do quite well for me and flowered. No offsets so far so I'll be collecting seed.
