This little beauty is Lapeirousia oregena, a member of the Iridaceae (Iris) family and native to the northwestern cape of South Africa.
This specimen was photographed in the Davies Alpine House at Kew Gardens in March, with Saxifraga x hornibrookii ‘Riverslea’ in the background. Alpine houses in early spring are some of my favorite places. They look like jewelers’ cases, full to bursting with tiny, colorful gems to catch the eye. Despite its tiny size, with each flower about the size of my fingernail, this Lapeirousia really stood out to me that day.
