Cultivation[]

Ipheion uniflorum has been grown in the UK since 1820, when bulbs collected from near Buenos Aires arrived in the country. It is recommended for growing in a well-drained position outside or as long-flowering pot plant in an unheated greenhouse. Various named forms are in cultivation, some of which may be hybrids. 'Wisley Blue' is a clear lilac blue; 'Froyle Mill' is a deeper violet blue; 'Album' is white. The cultivar 'Alberto Castillo', also white, has larger flowers and was collected in the 1980s by Alberto Castillo, the owner of Ezeiza Botanical Garden, from an abandoned Buenos Aires garden.
