Post Agave striata vs. Agave stricta
An Australian horticulturalist drew my attention to this very clear blog article.

It can be summarised, for horticultural purposes, as "impossible to tell apart except when in flower". Both spp. are variable in habit, leaf-form and size and the only way to tell them definitively apart is by measurements of the flowering parts.

Out of flower, the variations between individual plants of A. striata and A. stricta are greater than the differences between the spp. No wonder people get into circular debates about them.

I wonder if A. stricta shares any of A. striata's inexplicable hardiness.

There is one easy way to tell the difference - go to Mexico! Agave striata is common throughout the NE, Agave stricta is not very common in the Tehuacan Valley, several hundred km further south.

In cultivation I find it almost impossible to distinguish between the two as all the parameters that allegedly tell the two apart can vary and therefore overlap. I have several 'bought as' striata planted outside that have been fine over the years - I lost one plant a long while ago but all the rest do ok and one is now a regular flowerer (and confirmed as striata). I also have one plant that I feel is different enough to key out as stricta, which is the name it came with, but that has also proved to be hardy over many years despite the frost-free provenance.

Bottom line - unless you are 100% confident about the provenance of the seed your plant was raised from I would always have it down with a question mark.

Well, thank the gods it's not just me.

I bought a juvenile plant some thirty years ago and despite much research have never been able to be sure if it is striata or stricta. The pity is that if I have to wait for it to flower to make sure it'll already be on its last legs!

Kev, yes, I keep it frost free.

The problem is t's a very modest 10ft x 8ft and the plants are beginning to threaten the roof.

I got both striata and stricta , 1 year old seedlings survived -8 C with rain protection. Stricta nana however is not hardy. Striata subsp falcata is pretty hardy. Striata rubra is actually quitte hardy as well. Alot of agave and cacti from San Luis Potosi are quitte cold hardy, striata is very widespread.

Further to my previous post, I've just seen that my stricta/striata is coming into flower.

I get Agave stricta here from Mexico. It was a souvernir. On the picture you see them in habitat.
