Senecio polyodon



A species of Senecio from the mountains of South Africa. I haven't had it for long, but I rather like it. I expected it to be a lover of dry sunny conditions but have since seen it growing happily in moist shade at Rosemoor so perhaps it will survive here.
I learnt fairly rapidly that it needed to be planted in full sun, ideally in the greenhouse, and propagated frequently to keep it young.
Plants of the World online says:

"The native range of this species is Zimbabwe to S. Africa."

I bought it from Derry Watkins and should have taken more notice of her label, which said:

"Little bright purple daisies held well above narrow shiny leaves in mid-summer. Hardy perennial, likes sun and drainage. 24". "

The Flora of Zimbabwe says:

"Erect perennial herb, up to 75 cm. Leaves in a basal rosette, narrowly elliptic, up to 10 cm long, clasping the stem; margin coarsely toothed. Flowerheads white to purple, ray-florets absent.
In moist grassland, seasonally flooded areas and near vleis and marshes.
Note: Although this species is included in the Checklist of Zimbabwean Vascular Plants (Mapaura & Timberlake, 2004), its distribution appears to be unknown. No specimens of this species were found at the National Herbarium (SRGH) and its status as a Zimbabwean species is doubtful and needs further investigation."

The phrase "ray-florets absent" in the Flora of Zimbabwe raises a significant question.
