Description and Ethnobotany
| Growth Form | Scrambling shrub, able to grow up to 1 m tall and with a spread of 1 m wide. |
|---|---|
| Foliage | Leaves are obovate with crenulate margins, 10 to 25mm long, thin and light green in colour. The leaf axils are winged with ear-shaped appendages at the base of each leaf (see etymology). Another salient feature is the abundant axillary growth of leaves, resulting in many leaves of varying sizes being found all over the plant, and a distinctively dense and bushy appearance even in small plants. |
| Flowers | Flowers are pale blue, borne on rounded terminal clusters. Flowering continues throughout the year in Singapore; but only from summer through autumn in sub-tropical and warm temperate climates. |
| Habitat | Found in thickets and disturbed sites. |
| Etymology | Genus epithet 'Plumbago' derived from the Latin "plumbum" meaning "lead" (the metallic element). Named after a European species which was used to cure lead poisoning. Species epithet 'auriculata' from the Latin "auricula" meaning "ear", after the appendages at the base of each leaf which were deemed to be ear-shaped. |
Landscaping Features
| Landscaping | Known to be a scandent (semi-climbing) shrub in Mediterranean climates where it originates, but most often seen in the Singapore landscape as free-standing shrub masses or groundcover. It can also be used as a low hedge but requires frequent clipping. It is easy to maintain and forms a dense mass of green leaves and pale blue flowers which appear almost fluorescent when viewed in under low light. However, the flowers do not stand up well to being drenched; they also remain on the plant after they have wilted, which may result in periodic unsightliness after flowering. Suitable for borders, as underplanting or in containers. A drought tolerant plant, it prefers a bright, sunny position and well-drained soil as it does not tolerate water-logging. |
