Noteworthy Characteristics

Drosanthemum micans, commonly called Robertson vygie or Robertson dewflower, is a perennial, succulent subshrub endemic to the Robertson Karoo in the Western Cape province of South Africa. Mature plants will reach around 2' tall and spread to fill a 3' area with a densely branched, compact habit. The succulent foliage is semi-cylindrical in shape and will reach around 1" long and 0.15" wide. The stems are seasonally topped with 2" wide blooms creating a showy floral display. The flowers have numerous, narrow, yellow petals with orange-red tips and a contrasting ring of small, dark purple to black, filamentous staminoids (structures that resemble stamens).

The genus name Drosanthemum comes from the Greek meaning "dew flower" in reference to the glittering appearance of the young stems and foliage.

The specific epithet micans means "shining" or "glistening", in reference to the glittering appearance of the young stems and foliage.

The common names Robertson vygie and Robertson dewflower refer to the Robertson Karoo where this plant is native. The Afrikaans word vygie means "small fig", in reference to the shape and size of the fruiting capsules. Dewflower refers to the glistening leaves and stems which may appear to be speckled with tiny drops of dew. This is the result of swollen bladder cells which store excess water.


No major pest or disease problems of note.
