We first got interested in the aloes because of the medicinal qualities of the juice from the thick leaves of the plant. It is good for burns and especially sunburns. But it smells awful. For a while, adding aloe juice to things, including food, was all the rage. I haven't noticed that so much lately. The plants are relatively frost tolerant but burn out in direct sun in Mesa. They also grow like weeds and one plant can take over an entire flower bed if left to grow. These particular flowers are quite unusual.
