Pleasant succulent consisting of groups of rosettes at the apex of slender stems, which together form a soft and delicate cushion, sometimes tending to cascade. It has short and extremely fleshy leaves, roundish and only slightly pointed at the apex; the epidermis results of a beautiful bluish green, very clear, completely covered by a sort of whitish pruina that protects it from the atmospheric agents and confers them, at the same time, a matte, deeply delicate and elegant look. When properly exposed to sunlight P. rzedowskii is tinged with wonderful pink or purple shades, which make it even more particular and ornamental. The charm of this succulent is further amplified when, at the apex of long stems, blossom graceful flowers on the notes of greenish-white.
