This massive vintage plastic cactus measures 57 inches in height when fully assembled. The set includes nine 16" end pieces, five 20" end pieces, eight 18" base branches, one 21" center extension branch, four branch platforms, one base and one finishing branch mount. When fully assembled, there are four extra end pieces. To assemble, the bases are stacked on top of each other. They have 3/4" holes to accept a dowel rod, which you will need to provide in order to hold them all together and to stake the heavy assembled piece into the ground or a flower pot.
