Hoodia gordonii is a floral performer into a ripe old age, also when conditions of the season have not enabled the plant to present an all-over renewed appearance.
Such regeneration may be strong at stem-tips, never reaching down visibly to the dulled down lower parts of the cylindrical columns, where the dry tubercles persist impassively but protectively. Like bark, they cover the internal, juice-driven life events up and down the stem, from root to tip (White and Sloane, 1937; Shearing and Van Heerden, 2008; Le Roux, et al, 2005; iNaturalist).
