Nerine masoniorum

Nerine masoniorum is a species of flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae,[3] native to the eastern Cape Province of South Africa.[2] It is a bulbous perennial belonging to the group of nerines that have narrow evergreen foliage.[4] The thread-like leaves reach a length of 25 cm or more. The flowering stem is 15–25 cm tall, with up to 11 flowers arranged in an umbel. Each flower has six narrow pink tepals with wavy edges.[5] It flowers in late summer in cultivation, the first of the nerines to do so.[6] It has received the Royal Horticultural Society's Award of Garden Merit.[7]
