Description

In its natural setting, Sabulina michauxii can be found growing along rocky summits, woodlands, forests, ledges and rock crevices.  Its natural habitat includes rocky soil.    It has a low growing habit, growing in dense clumps and tuffs and often matted.  Small dished shaped white 5-petaled flowers grow as a form called hypanthium or floral cup.  That is a structure where the basal portions of the calyx (corolla) and the stamens form a cup-shaped tube that contains the nectar secreting organ.   Its taproots are woody and thickened with many branches.
