Dietes grandiflora 

Fairy Iris

South African gardeners can grow their native Dietes as if they were weeds. That hasn't quite happened in the UK yet but climate change seems to be making it more possible. Outdoor plantings are apparently doing well in parts of Cornwall. We'd still recommend growing these evergreen perennials in a frost free environment during the winter. 

They need a loam based potting compost such as JI No2, full light and good ventilation. The plants can form quite large clumps with the flower stalks rising to over a metre. 

The flowers are borne en masse at certain times - usually after rain in summer so water well when in growth. The individual flowers only last a couple of days but are born profusely and in quick succession. 

The fragile white petals resemble fairy wings, but can also magically disappear very quickly hence the name, Fairy Iris. 

During winter they become dormant so avoid watering and store in a frost free, dryish environment.
