Asparagus multiflorus greenish fruits

The green, spherical fruits of Asparagus multiflorus are starting to acquire purplish colouring on the plant in picture. This is appearing in skin spots or mottling, as well as a general suffusion of new colour. Fruit diameter is about 6 mm.

The fruits grow on longish stalks that appear jointed, as flowers or fruits that have dropped off earlier left uniformly short ones (Vlok and Schutte-Vlok, 2015; JSTOR; iNaturalist).
