The stamps:The four succulent species featured in the stamp designs are endemic to Australia. The designs show two aspects of each species: the foliage and the flower. The photographs are from the collection of Attila and Michele Kapitany – Attila has spent the past 40 years of his professional life researching, growing and promoting succulent plants to Australian gardeners and has written several books on the topic.
