Massonia depressa

Description

Massonia depressa, the hedgehog lily, is a species of flowering plant in the family Asparagaceae, that is native to South Africa. Growing to 10 cm (3.9 in) tall by 50 cm (20 in) broad, it is a bulbous perennial with two opposite leaves lying flat on the ground. A spiky cluster of white, yellow or brown flowers appears at the centre of the plant in winter. The flowers are uniquely scented like yeast, to attract pollination by gerbils and other rodents. The anther is exceptionally long - up to 2mm. The seed capsules are inflated, enabling them to be wind-borne. This species has been observed to be variable in the wild, and numerous attempts have been made to resolve its true relationships within the genus Massonia, so far without success. The Latin specific epithet depressa means “having a flattened appearance”, a feature common to all in this genus. When cultivated in a temperate environment, M. depressa does not tolerate freezing temperatures, so must be grown under glass in a cold greenhouse or similar. It requires full sun, and dry conditions during the dormant season (starting in spring). It has been given the Royal Horticultural Society’s Award of Garden Merit. Massonia grows from underground bulbs whose outer tunic is pale brown and papery or leathery. Two relatively broad leaves appear at the same time as the flowers, spreading out on either side, sometimes lying flat on the ground. The flowers are borne in a raceme, which may be short and held at ground level. There may be a "tuft" of green bracts at the top of the inflorescence. Individual flowers are pale in colour, white, or with green, yellow or pink tones. They are bell-shaped or somewhat tubular, with the tepals joined at the base forming a short or long tube. The stamens are more-or-less erect, with their filaments joined to the end of the tube formed by the tepals and also to each other, forming a small cup. The seeds are dull black. The species Massonia depressa has been shown to be pollinated by rodents, including two species of gerbil (Gerbillurus paeba and Desmodillus auricularis). Very few species of plant are rodent-pollinated.
