This is one of my favourite agaves mainly for the range of spines which can be large. There are several forms and it is one that causes heated discussions in the agave world as to what constitutes the form, or if they are all the same agave. The one below was my first form and I have posted it before, under a Halloween scary post.
This one has by far the best spikes but my current favourite is one of the variegated forms. This one belongs to friend. I have had my eye on it for a while now and always photograph it when I visit. This was it last year:
It has been fairly obvious it was on my wish list and last year he surprised me with a little offset. At the time the variegation was limited; you never really know with very young plants how they will develop. This is it today and the leaves are starting to get a really good variegated edge.
If you look at the older leaves you may be able to see they are split. This is one trait of this agave, if you don't water it for a while and it starts to shrivel up when you do water it the leaves are prone to split like this. This is unusal for an agave and takes a bit of time to get the watering right, especially in winter when you would usually keep them dry for months on end.
If it carries on like this it may look even better than its mother and that is not going to go down well. It is part of the fun of sharing variegated plants, wondering if you have given away a real star. Of course now I have this one, there is another one on my wish list; agave titonata black and blue!
