A young Crassula barbata inflorescence may have many flowers densely clustered on the erect stalk in a thickish structure called a thyrse. The stalk is fleshy, green to whitish.
Apart from the five, pointed, fleshy sepals there are also bracts under the flowers, hairy like the leaves of the basal rosette. The petals are closed here, the day maybe not to their liking. Almost all the flowers appear to be about equally developed at the time of the photo.
The inflorescence is sometimes much redder in the sepals than seen here, where only a hint of pink is present upon some of the sepals and petal tips (Frandsen, 2017; Vlok and Schutte-Vlok, 2010).
