Serruria cyanoides - Wynberg Spiderhead is a multistemmed shrub with lots of delicate, short, erect stems emerging from the ground. It has a single head per stalk. Se cyan has been atlassed at all of its known extant sites. The record on Suther Peak (north of the main Karbonkelberg population) must still please be confirmed. It was once common on the Cape Flats, and may still occur in the Tokai and Constantia Forests, and even at Rondevlei. The record north of Rooikrans also requires verification.

This is a Peninsula endemic - so seasonal data are crucial. We lack suffcient flowering and growth data for January to March, May to June, August to September and November.
