I could not decide which Agave shot I liked the best, so I'm posting the collection. Agaves leave what's called bud imprints; a ghost of where the last layer of spikes were pressing into the leaf buds below. I find them hauntingly beautiful. It's especially nice when the leaf color is blue...my favorite color of Agave. I have about 30 species and cultivars and I love them all. Speaking of collections, visit Lisa at http://lisaschaos.com/ to see the rest of the photo phanatics and their phantasia of phun photos.
