Plumbago auriculata
Lam.
Belesa, Cape leadwort, Blue plumbago, Cape plumbago
Evergreen shrub, 2-4 m high, erect, creeping, hanging, or climbing if it
finds a place to hold on to, abundantly branched, with delicate,
flexible, striated stems that bend under the weight of the flowers.
The leaves, green with the underside covered with whitish scales, are
simple, alternate, shortly petiolate, generally fasciculate, with a
decurrent blade, with two rounded auricles at the base, and with an
oblanceolate to slightly spatulate lamina, about 5-7 cm long by 2-3 cm
wide, and an entire margin.

Its small, sky-blue flowers, with lighter colour gradations and a darker
central longitudinal line, measure about 2.5 cm in diameter, and are
grouped in dense terminal clusters of about 10-15 cm in diameter.
Each flower has a tubular calyx about 10-13 mm long, glandular in the
upper half, and a bell-shaped or rounded corolla with five petals fused
at the base.
The fruits are small capsules containing a single seed.
It normally flowers between April and November, but it is common to find
specimens with flowers all year round.
It can be reproduced by seed, cuttings, or by division of bushes.
This species is native to South Africa, but has long been cultivated in
regions with a Mediterranean climate, both in public and private
gardens. It is a plant much appreciated for its exuberant flowering and
its ability to cover large areas with ease, making it ideal for
decorating walls, pergolas and fences.
