You are buying 5 really nice cuttings of the Heirloom type of Devil's Backbone / Jacob's Ladder / Red Bird Cactus / Slipper plant.(Pedilanthus tithymaloides).
This is the SOLID GREEN variety, the leaves and stems are solid green. Each cutting will be 8 - 10 inches long and will be unrooted (they root easily -- planting instructions are included -- just don't overwater!).
These plants aren't actually a cactus - they don't have any thorns to stick you - but they grow easily in moderately dry conditions and make a great addition to a rock garden or a great house plant! They are hardy to zone 9 and warmer so grow as a houseplant in colder zones.
Named Devil's Backbone or Jacob's Ladder due to the zig-zag nature of the stem and called Red Bird Cactus or Slipper plant due to the red flowers that form in the late winter to spring, these plants are EXCELLENT if you don't have a green thumb.
They make GREAT specimens for your rock garden or in any moderately dry, sunny spot. These plants are hardy to zone 9a, can be planted in full sun to bright shade and are PERFECT for xeriscaping very drought tolerant. In colder climates, they can be planted in containers and brought in during the winter or kept in a bright window in your home or office all year long. These plants can stand quite dry conditions, but will thrive with a moderate amount of water in well draining soil - don't overwater!
*Cautions: These plants do have a milky sap that is a skin irritant in some people, so take care when trimming your plants and don't allow the sap to get on your skin or in your eyes.
