You are buying 2 really nice cuttings of the unusual Pencil Plant/Tree/Bush (Euphorbia tirucalli) (aka: Rubber Hedge, Milk Bush). Each cutting will be it's own small 'tree', not just one stick or twig (see photo above for an example of a cutting). Each cutting will be unrooted (they root easily -- planting instructions are included) and 6" - 10" tall.
These plants aren't actually a cactus - they don't have any thorns to stick you - but they grow easily in dry conditions and make a great addition to a rock garden or even a nice house plant! These plants can grow in to large trees* in tropical areas or you can keep them trimmed down into bushes with lots of criss-crossing, round, pencil-like limbs.
These plants are EXCELLENT if you don’t have a green thumb, don’t like to do much in the garden or like to take long vacations! They make GREAT specimens for your rock garden or in any dry, sunny spot. You can practically plant them and forget them! 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. Treat as a cactus and allow soil to dry between watering.
*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.
I don't suggest allowing these to grow into large trees, as they do get brittle and break easily when very large.
