Gladiolus angustus

Quick Characteristics:

Gladiolus angustus L. is found in wet places on sandstone soils in the southwestern corner of the southern African winter-rainfall region. Growing from 60 to 120 cm high, it flowers in spring (October and November) with cream to pale yellow flowers with diamond spade shaped yellow markings outlined in dark red on the lower tepals. The species has a very long perianth tube, usually 7 to 10 cm, and the lower tepals are substantially shorter than the upper tepals. It is related to Gladiolus carneus and Gladiolus undulatus.
