Protea repens or commonly name Sugarbush, is the most
widely distributed of all Protea. Although it mostly
occurs on the flats, coastal forelands, lower and middle
mountain slopes, it has been found at altitudes up to
1500 metres. The natural habitat of Protea repens is the
Southern tip of South Africa. Protea repens is a small
evergreen shrub which may grow to about 5 meters but is
best kept at 2-3 meters in the garden. A very ornamental
plant. It looks wonderful in the garden and as a cut-flower
in a tall vase, particularly when massed.
Protea repens has quite hard, leathery leaves, which
protect it against most insect attacks and not much
damage is visible to the leaves, except from leave
borders. The leaves are elliptic and narrow, usually
greenish-yellow and about 13 cm by 1cm.
The shape of the flowers is very distinctive, chalice-shaped,
and forms an ice-cream cone seedhead. The flower
heads are actually clusters of tiny flowers surrounded by
bracts. The pointed and sticky flower bracts are cream
with the upper portions pink. The individual flowers
inside vary in colour from pure white to pink to
deep pink. The flowers are hermaphrodite, have both male
and female organs and are pollinated by bees. Flowering
all year round, depending on the locality.
The copious nectar produced by the flowers is loved by
birds and was widely used for sugar and syrup production
by South African colonists.
Bushes need to be pruned regularly to maintain their
shape and promote flowers with long stems. When the shrub
has finished flowering it is essential to cut off the old
flowers. This will allow energy to be used for the growth
of new stems at the end of which will be new flowers. It
is best to cut the flowering stem back to about 10-12 cm
from the preceeding branch.
Hardiness zone 9, (-5°C/25°F) in Winter. Protea repens
is one of the easiest, most adaptable and reliable Protea
in cultivation. It is tolerant of a wide range of soils,
from heavy clay to deep white sand. Plants tolerate both
coastal conditions and temperatures down to about -5°C,
although prolonged frosts, or frosts combined with cold
dry winds will cause damage.
The plant prefers light sandy soils. Requires well-drained
soil and can grow in nutritionally poor soil. This Protea
prefers acid soils and can grow in very acid soil. It
requires dry or moist soil.
Those plants are very sensitive to nitrates and
phosphates in the soil, these can prove toxic even at
moderate levels. When fertilizing, use a product which
contains no phosphorus. Plants may also suffer from
magnesium deficiency. Grow with a pH of 5.0 - 5.5.
It cannot grow in the shade. Dislikes high humidity or
windless days. Requires full exposure to the sun.
Requires a position with good air circulation, but
sheltered from cold winds.
