Flower sighted unsure if correct species
No interactions present.
I think you mean Senecio elagans, but I don't think it is that based on internet photos. The leaves look wrong. No other suggestions to offer!
Please note that there is a Southern African iSpot at http://za.ispot.org.uk where you are likely to get faster and more accurate identification of local species.
