Both Tillandsia australis and Tillandsia aeranthos are now flowering in the garden. They grew a little purple flower. The Tillandsia australis and aeranthos was given to us by, The. Funny enough the T. australis and T. aeranthos are from the same genus. But look at the size! Australis is gigantic and aeranthos is small. But you can tell they are family they both have same purple flower. They both look beautiful in our garden.
