Serruria elongata, the long-stalked spiderhead, grows sturdy, long flower stems, sometimes well over 30 cm long. The flowerheads are positioned in loose clusters near the stem-tips.
The cylindrical, silvery haired, bisexual florets start off in a flat-topped cluster, the perianth buds cohering as in picture. The peduncles are leafless, but small, ovate and pointed bracts are present. Upon opening the perianths morph into the complex appearance that fits the generic name of spiderhead.
The plant flowers from midwinter to midspring (Bean and Johns, 2005; iNaturalist).
