Crassula ovata
Plant
suitable for use on Green Roofs in the Durban Area
Crassula ovata
Is one of a number of plant
species which are presently being tested for their
suitability to be grown as Green Roof
plants in the Durban region that have initially shown good results.
They all
occur naturally within a radius of 50 km of the Durban
city centre
These
plants occur
naturally in shallow soils on the rocky cliffs in
the Kloof, Hillcrest and Shongweni areas of
Durban growing in full sun to medium
shade
Growth
habit
These
plants are small to medium growing evergreen succulent shrubs seldom
exceeding
2 metres, the stems as well as the leaves are highly succulent. They
reproduce
both vegetatively as well as by seed.These
plants are extremely decorative feature plants having dark green
succulent leaves
and a very neat growth habit. They produce masses of white flowers
edged with
pink over a long period during the winter months
Drought
resistance
In
their
natural habitat they are able to withstand reasonable periods of
extreme
drought due to their very succulent nature. From my experience of
growing these
plants I have found them to be very drought resistant.
Disease
and pest resistance
These
plants
are generally disease resistant however they are often heavily fed upon
by the
larvae of butterflies which at times do considerable damage to the
plants
Suitability
as Green Roof plants
From
my
many years of experience with these plants and from indications of the
plants
that are being tested under Green Roof conditions these plants
certainly give
the impression that they are going to be excellent Green Roof feature
plants
where larger plants can be grown.
Biodiversity
value in the Green
Roof landscape
They
create
robust habitat and protection for other green roof dwellers. They are
frequently
fed on by the larvae of butterflies, when in flower they attract large
numbers
of pollinating insects in particular honey bees.
Cautions and
precautions in the
Green Roof
application
None
that I
am aware of at the moment
Indigenous landscape
Design Specdialist
Bio-Diverse Indigenous Landscaping I design
landscapes and gardens that are Bio-Diverse as well as being pleasing
to the eye
Landscapes and Gardens that are Nature Friendly
I use my many years of landscape planning and design as well as
landscape construction experience coupled to my vast knowledge of the
requirements of nature to create habitat suitable for birds,
butterflies and other creatures to live and breed in.
I
always apply the basic principles of good landscape design to create an
aesthetically pleasing garden that at the same time satisfies the
living requirements of the target creatures that I would like to
attract. My speciality is to attract birds, butterflies and solitary
bees. I design and build Bio-Diverse Roof Gardens
So
let Ecoman design and create a garden for you that will
be a haven for wildlife such as birds, butterflies, frogs and lizards
in the number of species comparable to Kruger National
Park.
