Blue Giant Agave
An interesting and rarely seen agave relative that looks a bit like an agave trying to be a yucca with broad blue leaves (that aren’t sharp and stabby) and eventually forming a trunk up to 7′ tall. Grows well in places with cool summers as it’s from high elevations in Guatemala and southern Mexico, but requires a nearly frost free winter in order to survive, so better suited to growing in pots in colder climates.
Plant in extremely well draining soil in the brightest conditions if planting in ground. Otherwise it makes a fantastic container specimen and can be brought indoors when very cold weather is in the forecast.
