This spiky daisy grows at altitudes of 2000 metres or more from the Eastern Cape to the Drakensberg mountains in South Africa. Often found in large swathes, a natural sweep of Berkheya in full flower is quite a spectacular sight.
It's quite a showstopper in gardens too as the tall central spike can have numerous flowers open at the same time.
The large daisy like flowers are short lived but more will form on side branches throughout the summer. The soil must be very well drained so add grit if necessary and provide shelter such as a south facing wall.
They can tolerate light frosts and cold if kept as dry as possible throughout the winter months. Planted in a block there isn't a cat in the world who'll pee amongst them. Very prickly.
Rich green, grey
Very well drained
