Technically, that is called whorled phyllotaxy, which is the term for when a plant has more than 2 sets of leaf/secondary growth growing at each node, instead of 2, which is simply 'opposite phyllotaxy', or 1, which is 'alternating phyllotaxy'.
Triploid would mean that the plant has 3 chromosomes- impossible to determine without rather expensive equipment or complicated breeding tests.
