is one of a number
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.

Cyanotis speciosa plants occur naturally
mostly in full sun on rocky outcrops in the
area where they grow in very shallow soils mostly with little or no
from other plants.
plants are low growing evergreen scrambling plants that primarily

natural habitat they are able to withstand long periods of drought due
succulent nature. From my experience of growing these plants as pot
have found them to be very drought resistant.
Disease and pest resistance
are generally very disease resistant. Although they are very drought
they can also withstand very wet conditions without rotting.
Suitability as Green Roof plants
experience with these plants and from indications of plants that are
tested under Green Roof conditions these plants certainly give the
that they are going to be first rate Green Roof ground cover plants.
Cyanotis speciosa requires a growing medium that has a higher percentage of well matured leafmould
than for the other plants that we have tested to grown at it´s optimum.
Biodiversity value in the Green
