The pompon tree is one of the best known and well-loved indigenous
trees, tough enough to be used as a street tree and small enough
to fit into most gardens. When in flower at Christmas it looks like
a giant candy floss, as the tree transforms into a cloud of soft
pink balls. Its natural home is the eastern part of South Africa
where it grows on the margins of forests, wooded hill slopes and
in stony kloofs.
Dais cotinifolia is a small tree growing only to 6 metres,
with a lovely rounded, leafy crown. It can be single- or multi-stemmed,
with the brown stems covered in small speckles of whitish cork.
The smooth, simple leaves are bright green, sometimes with a slight
bluish tinge on the upper side. The veins of the leaves are a translucent
yellow colour, forming very clear patterns as they run through the
leaves. The leaves are usually scattered up the branches or crowded
at the ends of the branches. In very cold areas the trees are deciduous,
but in warmer climates like Cape Town they only lose their leaves
for a short time at the end of winter.
The trees flower in early summer, any time from November to December.
In the city of Cape Town the street trees flower in November and
in the more protected environment of Kirstenbosch, the trees only
flower in December. The new flower buds look like lollypops, with
big round heads on long thin stems at the end of the branches. The
green heads pop open with the many small flowers in tight bunches
inside, looking like pink fluff balls. For about three weeks the
tree flowers in profusion. The tiny black seeds are formed in the
bottom of the little flowers and are ready to collect about month
or two after flowering. After flowering, the green cup shaped bracts
that held the flowers, become hard and brown, remaining on the tree
for many months. These dried "flowers" can be used for
decorations, model building and children's games.
Growing Dais cotinifolia
This is a wonderful tree for the garden, fast growing, fairly drought
resistant once established and frost hardy. When planting, choose
a sunny position and prepare it well by digging a large hole of
about 1 m x 1m, adding lots of compost and bone meal. Water the
young tree regularly during the summer months until it is well established,
which usually takes about two years. Placing a thick mulch of compost
around the base of the tree helps to prevent water from running
away, keeps the soil moist and cool, suppresses weed growth and
slowly releases nutrients into the soil.
The tree grows easily from seed and usually seeds itself all over
the garden. Sow seed in spring or early summer in seed trays filled
with a well-drained medium. Cover the seed lightly with fine milled
bark or sand, place in a shady position and keep moist. To improve
the germination, treat the seed with a fungicide that prevents damping
off. The young seedling can be potted up as soon as they are big
enough to handle. The trees grow fast and reach their full height
within 4 to 5 years, flowering from about their second year. The
trees can be lightly pruned if necessary, young trees becoming very
bushy if the leader is trimmed. Flowers are produced on the previous
year's growth, so any pruning should be done after flowering.
Breaking a branch off this tree is quite difficult because the
bark tears off in long strips, from which accounts for its common
name, *Kannabas. This is a typical characteristic of the family
Thymelaeaceae to which Dais belongs. Eve Palmer notes in her description
of Dais cotinifolia that the Africans, who use the bark as
thread or cord, say that it has the strongest fibre of any tree
in KwaZulu-Natal.
Eve Palmer also mentions the interesting fact that Linnaeus founded
the genus Dais in 1764. In this genus there are only 2 species,
Dais cotinifolia from South Africa and one other species from
Madagascar. Dais means a torch in Greek, and the genus got
its name from the resemblance of the stalk and bracts holding the
flowers to a torch about to be lit. The leaves resemble those of
another genus Cotinus, hence the species name cotinifolia.
* Kannbas According to C A Smith in Common Names of S A
Plants (1950) this name is incorrect and was the result of a confusion
between Gonna and Kanna. Kanna is a Hottentot name
for Sceletium (Kougoed), a succulent plant highly valued
for its narcotic effect when chewed. Gonna is a collective name
used by the Hottentots for several species of Thymeleaceae
