Stypandra Glauca

dnaoodb: professional biology database , biology encyclopedia

in biology, Stypandra Glauca (Latin:Stypandra glauca R.Br.) is a genus of perennial flowering plants in the family Asphodelaceae , subfamily Hemerocallidoideae. Its distribution is widespread from south east Queensland through to Western Australia. A single specimen has also been collected from New Caledonia. Stypandra glauca distributionAlthough quite tolerant of drought it is not found in extremely arid areas. It is not considered to be at risk in the wild; however, very few have been collected in South Australia. Due to its variable characteristics and wide distribution collections have often been incorrectly described as new species. It is now widely accepted that there are two species within the genus Stypandra. Stypandra glauca is the most widely distributed species with S. jamesii endemic to a small area in Western Australia.

Although it has the appearance of a shrub, S. glauca is actually a multi stemmed tufted plant. It has long lanceolate leaves which hug the stem. The leaves are generally blue/green in colour, with some variation upon this theme. Older leaves turn brown/black, which gives the plant a striking appearance. It can reach heights between 0.6 and 1.5m. The pretty flowers of S. glauca droop terminally from slender stalks; they are usually blue in colour or occasionally white. The flowers are bisexual with prominent yellow filaments. Flowering occurs in early spring, less often in winter. The fruit is a black capsule and leathery in appearance. Stypandra glauca also reproduces asexually via rhizomes.

Stypandra glauca tolerates drought and frost extremely well, making it a good choice for modern gardens. This perennial plant can survive for many years with nothing more than some basic care. Plantings should be done in a position with good drainage and full to part sunlight. The ideal soils are sandy, granite, shale, limestone or clay. This plant will grow well on a bare plot and it will also tolerate plantings within grasses and herbs that do not overshade it. A good companion plant is Dianella revoluta, also a member of Phormiaceae. Although there are some similarities in the appearance of the flower, the fruit and foliage of these plants are quite different.

Propagation from seed has had variable results. The best results have been found when sowing the seeds directly in the soil outdoors during autumn. Patience is required here as S. glauca has been known to sprout months after being sown. A more reliable way to propagate this plant is to divide up an existing plant and re-plant the divisions in the cooler months when growth has slowed. Divisions should be quite large to increase the chances of survival. Naturally occurring S. glauca tends to thrive after fire. To recreate fire conditions, once a year remove old growth at the base and add fertilisers to the soil.

Stypandra glauca may not be suitable for well manicured gardens as the older growth blackens. This problem can be alleviated with pruning or by planting in amongst other plants. When drought persists there is a tendency for fewer flowers to appear which may also lessen its appeal. With a little watering the flowers should appear on mass, providing a brilliant display of colour. Stypandra glauca looks great in rockeries or natural plantings. The older blacker growth provides a strong contrast in colour with the younger blue/green growth, which is especially attractive when placed against a feature wall.

Division Propagation


Stypandra glauca is a perennial herb with flowering branches to 30 cm (12 in) high and up to 1 m (3 ft 3 in) wide at the base, becoming shrub-like and about 1.5 m (4 ft 11 in) high when not flowering. The leaves are stiff, pale green to bluish, narrowly lance-shaped, stem-clasping in an alternate, opposite arrangement, and are up to 200 millimetres long. The drooping, blue flowers are borne in clusters at the end of stems, about 14 mm (0.55 in) long, about 20–30 mm (0.79–1.18 in) across, each petal about 15 mm (0.59 in) long, prominent yellow anthers, pedicel thread-like and curved. Flowering occurs from July to November and the fruit is oblong to oval-shaped capsule, 8–12 mm (0.31–0.47 in) long.

Distribution And Habitat

Nodding blue lily is a widespread species growing on a variety of soils including sand, granite, shale, limestone and clay sometimes in woodland or mostly in dry forest.

Ingestion of flowering plants has been found to cause blindness in goats.
