Plumbago auriculata 'Alba' (White Plumbago) - An upright mounding evergreen shrub that reaches 4-6 feet tall with long whip like branches that arch outward holding 2 inch long oblong yellow green leaves that darken with age. It forms a rounded mound or can be pruned and or allowed to climb on other plants or structures. Nearly year round, with peak from spring through fall, appear inch wide five petaled pure white flowers on inch long tubes held in multiple flowered clusters at the branch tips. The fruit that follow have sticky hairs so best not planted along a pathway where they get stuck to clothing. Plant in sun or part shade (where it blooms less) in a fairly well drained soil and water occasionally to infrequently – tolerates low water conditions but looks better with an occasional irrigation. Hardy and evergreen to 25° F and reportedly root hardy to 10° F and useful down to USDA Zones 8. Tolerates seaside conditions. Cape Plumbago flowers on current year's growth so prune to control size and to refresh the plant in late winter when flowering the least. In the garden can be a nice white flowering large mounded shrub for background planting, a large scale groundcover that is good for erosion control on slopes or can be used container specimen. It adds a tropical feel to the garden and resistant to deer predation and good for attracting butterflies to the garden both as a larval host for some species and for food supply to others. Plumbago auriculata 'Alba' is similar in all respects to the species except it has white flowers instead of pale blue flower. We also grow a select blue form called Plumbago auriculata 'Imperial Blue', is a more compact than the species with larger and darker royal blue flowers. Plumbago auriculata is native to southern Cape Province, Eastern Cape and into KwaZulu-Natal in South Africa where it inhabit scrub thickets called "valley bushveld" and shares much of this habitat with the Cape Honeysuckle, Tecomaria capensis. The name for the genus comes from the Latin word 'plumbum' which means "lead" a named given by Pliny for a plant believed to cure lead poisoning. The specific epithet comes from the Latin word 'auricula' meaning "the ear" and the adjectival suffix 'atus' meaning a likeness to in reference to the base of the leaf. This plant was long known as Plumbago capensis, as it was so named in 1794 by "the father of South African Botany", Carl Peter Thunberg, for the Cape region it came from until it was realized that the French naturalist Jean-Baptiste Lamarc had previously brought the plant to the East Indies in 1786 as a garden plant and named it Plumbago auriculata. Another common name for this plant is Cape Leadwort but this name comes primarily from association with the European species that were formerly included in the genus Plumbago, but are now in the genus Ceratostigma.
The information about Plumbago auriculata 'Alba' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
