I wish to experiment with green roofs and I wish to know if you can
suggest me Victorian native plants like grasses, tussocks, prostrate,
groundcovers, alpines, succulents, small shrubs, etc. that would
easily grow in 5cm/10cm (max 15cm) of media and that could withstand
period of dryness.
Green roofs will maybe have a grey water irrigation system but my aim
is having self-sufficcient environments with minimum man intervention.
For this I thught to use a special soil media mixed with Biochar.
The uniqueness of a green roof is that plants will have to perform
under extreme temperature flactuations and be adapted to period of
intense heat and intense rain (like, I think, many alpines do). So
they need to be more resilient and have high regeneration
characteristics.
Fluctuations of temperature, intense heat and possible periods of
drought, sounds like some desert plant might be worth checking out
to,they'll prolly grow quicker then alpines to; although i couldn't
suggest any species.

suppose best would be a plant nursery that deals with native plants.
Another thing you need: the plants should develop a "carpet" of roots
in order to retain the soil on your roof. But you don't want something
like buffalo grass that sends killer roots and finds every crack.
You might consider looking through the Flora of Melbourne or some of
the small salt bushes such as Atriplex semibaccata, Einadia nutans,
and Enchylaena tomentosa all have colourful red berries and are
extremely tough also some of the lilies may survive as they have a
tuber that can store food during summer and then reappear after Autumn
rains.

Recently a native grasses expert from the Victorian Department of
Sustainability and Environment recommended the following native
grasses for a lawn in the Melbourne area:
Weeping Grass (short, spreading form only)
Slender Wallaby-grass
Kneed Wallaby-grass
To a lesser extent most other Wallaby-grasses can also be used for
lawn. All Wallaby-grasses will take mowing, but do not spread into a
turf.
