Description

The species will sometimes reach heights of 3 metres, though usually between 0.45 and 1.8 metres, and can branch out to 0.9 metres from upper parts of a solitary basal stem. V. nitens does not possess a lignotuber

. The leaves are needle-like, but soft, and are uniform as either a stem or floral leaf. The branching arrangement is described as corymbose, whereby the terminus of the lower branches extend to the level of the upper ones; the habit is notably slender in this species. Combined with the 'corymb-like' arrangement of the compounded single flowers, the presentation of the numerous flowers is flattened to only slightly rounded. The bunched mass of flowers are sweet in scent and vary in colour from bright glistening heads whose petals are golden, to orange, to a lemon yellow colour, in the taller (3 metre) plants of the Gingin area. The style in this species of Verticordia unfurls to its full length after the flower bud opens, fern-like, rather than being folded or increasing its length afterward.

Distribution

Verticordia nitens is restricted to the Swan Coastal Plain, its range extends as far north as Moore River

The plant has often been situated in the path of urban development. This encroachment on the plant's habitat is likely to place the species under duress if continued.

Ecology

V. nitens has been studied for its role as an example of a pollination by an oligolectic species of bee, a relationship described in 1992. The flowers are not attractive to typical insect pollinators, except for a single species of solitary bee  Euryglossa morrisoni (or Euhesma

), which feeds on nectar, pollen, and the oil retained on the anthers of this species and V. aurea.

The species is not considered to be threatened by extinction as it is common and populations are large. Naturally occurring plants have been heavily targeted for the cut flower industry, intermittent reports from 1993 record trends upward of 250,000 stems per annum, but the plant recovers well after harvesting. These later figures show a reduction after closer scrutiny of harvests, though much was obtained from private land, leading to increased sustainability when combined with greater care by pickers. V. nitens records in the early 1980s were 83 000 bunches, the majority of the 2 000,000 verticordia stems in an annual harvest that sometimes permanently damaged the shrubs.

Cultivation

The plant was regarded as highly desirable by gardeners in England. The spectacular display, "strikingly beautiful", was expected to be marketable, yet it has presented difficulties in its propagation. It was introduced to English gardens in 1840, but was not known to have flowered until 1861. The introduction to the eastern states of Australia has met with some success, due to the refining of the technique of propagation and the application of early pruning.

Later cultivation techniques made use of cuttings from lower parts of the plant, propagated from soft to semi-hardened wood, to produce longer living specimens. Cuttings taken between autumn to spring strike readily. Seedlings produced in cultivated gardens are rare, due to the absence of its pollinator. The need for study and development of cultivation techniques was identified by Alf Gray in 1966, and suggested this was not beyond regular commercial interests. Early attempts showed poor development in root structure, and susceptibility to fungal diseases present barriers to development as a crop or garden plant. The species has been less successful as an introduction to the eastern states, suffering fungal conditions after rains and remains vulnerable to root rotting—attributed to Phytophthora

—in dryer conditions that spare other plants. All members of V. sect. Chrysorhoe are noted for the vulnerability to infection of the rapid growth of soft wood, but this is especially destructive to V. nitens in cultivaton. Controls include pruning below sites of infestation, which often appear near the growing tip, results in bushier and more resilient plants for gardens, and study groups have trialled the removal of flowers after downpours. White oil controls used on other verticordia are damaging to V. nitens. Techniques for cultivation for the cut flower industry, replacing the natural harvest, require further development for commercial viability.

Cultural use

The plant has traditional names Kodjeningara and Kotyeningara, and common names such as Glistening Verticordia or those deriving from Morrison—later extended to similar species—these include Morrison Featherflower, Morrison-flower, and Orange or Yellow Morrison.

. Cuttings of the flowers retain colour and perfume, for up to 12 months, and this is one of few Verticordia species that can be hung and dried immediately, without a period in water. Another technique applied to V. nitens involves steeping cuttings in glycerine and hot water before drying, this affects colour but avoids flowers and leaves becoming brittle. They probably comprise the greatest part of Verticordia exported by the state's cut flower industry.
