Geissorhiza radians
Geissorhiza radians or winecup flower is a highly threatened species from the Iris family with fewer than 10 remaining sub-populations growing in south-western Cape, South Africa.[1] The deep purple flowers with large, red centres grow is dense colonies which makes for a spectacular flower displays from mid-September, particularly around the town of Darling. Its seasonally wet lowlands habitat is however becoming increasingly threatened with more than 80 % of its original habitat now permanently transformed into agriculture or urban sprawl and the remaining populations threatened by encroaching invasive alien vegetation and fertilizer runoff. The dark-centred flowers aim to attract specific pollinators from the horsefly family (Tabanidae), but the specific interactions still require additional investigation.
