Crassula obovata  var obovata

Plant suitable for use on Green Roofs in the Durban Area

Crasula obovata var obovata

Crassula obovata  var obovata (Stonecrop)
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

The plants we are growing were found growing in full sun in very shallow sandstone soils of north facing cliffs inland of Durban overlooking the Umgeni River Valley at Inanda. I have since also found this plant growing in a number of other localities in and around the Umgeni valley, as well as other localities near to Durban all growing on sandstone outcrops.

Growth habit
A small spreading leaf succulent with a tuberous root system. They reproduce vegetatively as well as by means of seed. In cultivation they have been observed to multify rapidly .
Decorative value
These plants are being grown for their neat growth habit and attractive flowers

Drought resistance
These plants can survive periods of drought.

Disease and pest resistance
Susceptible to rotting if they do not have good drainage. The are also very susceptible to fungal attack of the leaves during long periods of hot overcast conditions with intermittent light drizzle.

Suitability as Green Roof plants
These plants are valuable in plantings in shallow soils that are going to get the very minimum of or no water in winter as well in combinations with other plants that do not have a very vigorous nature. They have a prolonged dormant period that co-incides with the dry winter period making them very ideal plants where the soils are very shallow and they do not get competition from larger more vigorous plants.

Biodiversity value in the Green Roof landscape
Their flowers attract large numbers of insects in particular bees.

Cautions and precautions in the Green Roof application
Care must be taken to ensure good drainage.

Ecoman Durban Indigenous Landscape Design Consultant

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.
