Sweet Leaf Bush
II Scientific Name: Sauropus
androgynus
Family: Phyllanthaceae
I find the Sweet Leaf bush is one of the most useful plants in my
garden. Its great to nip a few new tips off as I walk by and enjoy
their fresh flavour or pick a handful of tips or leaves just before a
salad meal to eat instead of bland lettuce. The leaves and tips do not
store well as they go limp but are still good to eat with midday
sandwiches when bush, fishing or a field trip. If you're in a hurry,
cut a stem off and take the whole thing to the table. If you close your
fingers at the start of the stem and strip all the leaves off the tip,
it leaves a 'rosette' of leaves in your hand, ready to pop in your
mouth. What could be fresher?
The plant will grow readily from a cutting 40 mm long in warm weather.
As their root systems spread, a stem with a few roots on can be
detached using a sharp spade for quicker propagation. They grow little
in our winter here in Mackay, but then we don't have many salads. My
bushes have many flowers but very few fruit set, so I have no
experience with seed propagation. The odd seedlings do grow up round
the area of a well-developed bush, but mine usually get smothered by
mulch which they love. I don't fertilise as such but they do get
compost. It grows in most types of soil-but I think it does better in
the heavier ones. It loves water, but can't swim.
During the wet, unless they are heavily harvested, they will grow over
2 m high and then they will tend to fall over or outwards. Putting a
rope around [halfway up] will stop the out -spreading and a stake will
stop it falling over. I find it easier to hack off half the growth,
about a metre, and as the re-growth gets to a usable height, cut
another half off. Also, in autumn they are cut down to a metre.
According to the information I've gathered, they will cope with 95%
shade. It's native habitat is the under storey in a primary rainforest
yet I grow mine in full sun. The fruit and flowers are also edible. I
can vouch for the flowers, but never tried the fruit.
Culinary uses: Stir-fry dishes, scrambled eggs and any dish that calls
for parsley or spinach. [I have both parsley and Ceylon spinach which
we do cook, especially the latter, so I can't vouch for how sweet leaf
cooks. It's great raw, so when you are onto a good thing, stick with
it. Like the leaves of the drum-stick tree (Horse radish tree) it would
be labour-intensive to gather enough to cook. Ceylon spinach and
parsley take far less time]. In Malaysia, there are the occasional
reports of headaches caused to some people after heavy consumption.
Another source of information reports "excess consumption of leaves
causes pain in limbs". It also says "seeds are borne in abundance".
I've had no such problems. Who can define 'heavy' or 'excess'?
Young leaves can be eaten raw. [I eat leaves at all green stages and
find the mature ones sweeter.]

not a problem.
