Aporocactus 'Melanie' is a very peculiar and impactful species, also known by the common names of 'foxtail' or 'rat's tail'. Its stems are truly beautiful and can reach up to one meter in length, which is why it is often placed in a hanging vase, so that its stems can hang down and show themselves in all their majesty. It takes on a bright green color and the tips may be slightly lighter and reddish. Along the stems there are many small thorns.
