How to: Garden in the shade with Illawarra natives

Gardening in very shady areas is often really tough. And what happens when you try to limit yourself only to plants that grow locally? Nothing on the list!?! That can be a problem in many parts of Australia, but we are lucky in the Illawarra that the east-facing escarpment allows a lot of shade-loving plants to grow and flourish. And a range of other plants are happy in dappled shade as understorey plants beneath the lighter canopy provided eucalypts. 

There are heaps of local plants that are suitable, though not all work in all types of shade, and very few will thrive in full, heavy shade. But here are a few ideas to get your thinking cap on. 

Settlers' Flax (Gymnostachys anceps) is a tall strap-leaved plant that grows in deep shade, but can also cope with some light. It has bird-attracting blue fruit and a great vertical structure.

These fruit are only just starting to form and are still
green. Later they will enlarge and become blue. (Photo

Several of the local ferns also cope with lots of shade, though they will generally also appreciate a moist position.

new growth. It will take part sun too.

Gristle Fern (Blechnum cartilagineum) may have an
unappealing name, but it's a great tough mid-size
fern and forms large stands in good conditions.
Jungle Brake (Peters umbrosa) is a larger and quite coarse-
leaved fern that copes with shade and dry periods.

Last but not least, this is Sickle Fern
(Pellaea falcata), which looks and
grows similarly to the weedy Fishbone
Fern (Nephrolepis cordifolia). Its
leaves are a bright shiny mid green. 
There are also a few shrubs that cope with lots of shade, and many more that like dappled sun. I'll focus on the more shade-tolerant ones here. These are generally suited for planting in the narrow strip between a house and the boundary fence, often a shady and difficult area to manage.

The Small-leaved Bleeding Heart (Homalanthus stillingifolius)
is a very hardy shrub to 1.5m with soft, heart-shaped leaves.

This shaggy shrub is a Bolwarra (Eupomatia laurina), which
can actually become a tree, but is easy to maintain in
shrub form if preferred. It copes with a range of light
conditions including shade. (Photo by Kath Gadd.)

interesting round fruit. (Photo by

And of course the classic Orange Thorn (Pittosporum
, but previously Citriobatus pauciflorus).
It will grow in dappled to heavy shade and can be shaped
or hedged. It also makes excellent shelter for small
birds. (Photo by Kath Gadd.)
There are plenty other options but I don't want to go on for ever. I will cover more plants in a future post. Most of these plants are fairly easily available in the Illawarra region.
