Schenkia spicata aka Schenkia Spicata
Taxonomy ID: 17908
Schenkia spicata, commonly known as spike centaury or spiked centaury, is an annual (occasionally biennial) herb belonging to the family Gentianaceae and order Gentianales.
The species is native to a wide Old World range encompassing North Africa, Europe, and Asia, with historical records also from Australia — though Australian populations are now treated as a separate tetraploid species, Schenkia australis, following the discovery that European specimens are diploid while Australian ones are tetraploid.
Plants typically reach around 0.6 m in height. They tolerate a range of soil conditions including light sandy and medium loamy soils, with adaptable pH tolerances from mildly acidic to mildly alkaline, and prefer dry to moist, well-drained substrates. Growth occurs in full sun to semi-shaded positions. Flowers are hermaphroditic and are pollinated by bees, flies, and beetles. Propagation is by seed, sown from February to May with germination occurring in approximately 3–8 weeks at 24°C.
In traditional medicine, the plant has been used as a stomachic, particularly for digestive complaints including dysentery and diarrhoea, though its medicinal rating is low. No edible parts or significant other uses are documented.
Common names
Schenkia Spicata, Branched CentauryMore information about Schenkia Spicata
How difficult is Schenkia spicata to grow?
Schenkia spicata is an undemanding annual herb that tolerates a range of well-drained soils from sandy to loamy, adapts to mildly acid through mildly alkaline pH, and grows in full sun to semi-shaded conditions. Propagation is straightforward from seed. No special care requirements are noted in available sources.
How big does Schenkia spicata grow?
Plants typically grow to around 0.6 m (approximately 2 feet) in height. No mature spread information is available in current sources.
Where is Schenkia spicata native to?
Schenkia spicata is native to a wide Old World distribution spanning North Africa, Europe, and Asia. It was historically also recorded from Australia, but Australian populations are now recognised as a distinct species (Schenkia australis) following molecular studies.
How much water does Schenkia spicata need?
The plant prefers dry to moist, well-drained soils. It is tolerant of drier conditions and does not require consistently moist substrate.
What soil does Schenkia spicata prefer?
Schenkia spicata grows best in light sandy to medium loamy, well-drained soils. It is adaptable to mildly acidic, neutral, and mildly alkaline pH. It does not tolerate waterlogged conditions.
What light does Schenkia spicata need?
The species tolerates both full sun and semi-shaded (light woodland) conditions. Full sun is acceptable and likely preferred in the open habitats it naturally occupies.
How is Schenkia spicata propagated?
Propagation is by seed. Sow from February to May; seeds germinate in approximately 3–8 weeks at 24°C. As an annual or biennial, the plant completes its life cycle within one to two growing seasons.
How is Schenkia spicata pollinated?
Flowers are hermaphroditic and are pollinated by insects, specifically bees, flies, and beetles.
What are Schenkia spicata flowers like?
Flowers are hermaphroditic, typical of the Gentianaceae family. Pollination is carried out by bees, flies, and beetles. No further description of flower colour or structure is provided in currently available sources.
Is Schenkia spicata edible?
No edible parts are known for Schenkia spicata. The PFAF database records an edibility rating of 0 out of 5.
What medicinal uses does Schenkia spicata have?
Schenkia spicata has traditional use as a stomachic, used particularly in cases of dysentery and diarrhoea. Its medicinal rating is 1 out of 5, reflecting minor documented use.
What other uses does Schenkia spicata have?
No other uses beyond limited medicinal application have been documented for this species. The PFAF database records an other-uses rating of 0 out of 5.
Are there varieties of Schenkia spicata?
In 2004, Centaurium was split into four genera, and the Australian populations formerly assigned to this species were recognised as a distinct tetraploid species, Schenkia australis. European populations remain as the diploid Schenkia spicata. No cultivated varieties are known.
