Ceratostigma plumbaginoides

Ceratostigma plumbaginoides, the hardy blue-flowered leadwort, is a species of flowering plant in the plumbago family, native to China, where it is known as 蓝雪花 (pinyin: lánxuěhuā; lit. 'blue snow-flower').[2]

Description

[edit]

Growing to 50 cm (20 in) tall and broad, it is a mat-forming herbaceous perennial with small ovoid leaves and bright blue flowers in late summer and early autumn. The leaves may turn red or purple before falling.

Distribution

[edit]

Ceratostigma plumbaginoides is native to eastern China, specifically Beijing and the provinces of Henan, Jiangsu, Shanxi and Zhejiang. It is usually found in rocky places, often in foothills.[2]

Scientific name

[edit]

Ceratostigma is derived from Greek, meaning 'horned stigma'. This is in reference to the 'shape of the stigmatic surface'.[3] The Latin specific epithet plumbaginoides signifies its resemblance to plants in the closely related genus Plumbago.[4]

Cultivation

[edit]

Ceratostigma plumbaginoides is grown as an ornamental plant in temperate climates, valued for its late season colour. It is hardy down to −10 °C (14 °F), but prefers a sunny, sheltered position in moist, well-drained soil. As it can become invasive, it is particularly suited to growing in a pot, or crevices in a dry stone wall.[5] It has gained the Royal Horticultural Society's Award of Garden Merit.[6][7]
