Nerine undulata

Nerine undulata syn. N. crispa is a species of flowering plant in the subfamily Amaryllidoideae of the family Amaryllidaceae, that is native to the eastern Cape of South Africa. Growing to tall, it is a bulbous perennial with narrow grasslike leaves that are almost evergreen, and umbels of 8-12 slender, crinkled pale pink or mid-pink flowers 5 cm across in autumn.
The Latin specific epithet undulata means "wavy, undulating", in reference to the crinkled tepals of the flowers.
A white-flowered cultivar, N. undulata 'Alba', has been given the Royal Horticultural Society's Award of Garden Merit. It is hardy in mild or coastal areas of the UK, but requires a sunny, sheltered spot.
