Moraea aristata (D.Delaroche) Asch. & Graebn.

Scientific Name and Growth Form

Moraea aristata (D.Delaroche) Asch. & Graebn. is a winter-flowering bulb geophyte that produces large, striking flowers.

Stem and Leaf Morphology

It grows 25–35 cm (9.8–13.8 in) tall and sometimes branches once, with a single linear leaf growing from its base. This leaf is usually longer than the stem, and often trails along the ground. Both the stem and leaf are hairless.

Corm Characteristics

The species' corms have a diameter of around 15 mm (0.59 in) and are covered in pale fibers.

Flowering Period and Placement

Flowers bloom in September, growing at the end of the stem, or sometimes on short side branches.

Outer Petal Features

Each outer petal is white, with a large iridescent blue spot at the base. These blue patches are outlined in violet, or sometimes yellow, and have a broad, black, hairy base.

Tepal and Inner Petal Features

The tepal claws are yellow, speckled with black or violet. The inner petals split into three lobes, with a long, straight central cusp.

Flower Longevity

While each individual flower lasts only three days, several flowers are produced over a period of three to four weeks.

Seed and Capsule Features

Its seed capsules are oblong in shape and split open from the top, holding light brown, angular seeds.

Native Habitat

This plant naturally occurs only in Peninsula Shale Renosterveld vegetation in northern Cape Town.

Habitat Loss

Due to urban growth, most of its original habitat is now covered by urban sprawl.

Remaining Natural Population

Until recently, the only surviving natural population was found in the grounds of the South African Astronomical Observatory in the suburb of Observatory, near the foot of Devil's Peak. This tiny, isolated population is not sustainable long-term due to low genetic diversity and ongoing human disturbance.

Conservation Reintroduction

In 2017 and 2018, the species was reintroduced to Rondebosch Common, giving new hope for its continued survival in the wild.

Naturalized Range

The species has also become naturalized in Australia.

Pollination

This species, commonly called the blue-eyed uintjie, is pollinated by monkey beetles, which are drawn to the center of the flowers by the blue nectar guides on the petals.

Seed Dispersal

Its seeds are dispersed by wind, and seeds are released when the seed capsules split open during summer.
