Mountain Pepper is the first plant selected to be featured, chosen for numerous reasons as you’ll come to learn. Firstly, as the common name suggests this plant has culinary and bushfood appeal. Crushing the leaves releases a sweet, spicy note to the olfactory senses, but it is not until one samples the leaf or berries that the ‘pepper’ can be truly appreciated. My first experience came after reading about a dirty joke played upon the author of Herbal Harvest, Greg Whitten.(6) My curiosity in the “mouth on fire” experienced at the expense of Whitten, led me too to sample a leaf from a population of Mountain Pepper growing on the flood plains of the Acheron River, Buxton, Victoria where the rare Eucalyptus crenulata (Buxton Blue Gum) calls home. As described by Whitten, an aromatic, mildly spicy flavour initially brushes the palette, then after a short delay of maybe 10 seconds or so, the enzymes in my saliva unpacked a natural ‘Warhead’ constituent which alluded me to the reason why this plant doesn’t experience a great deal of herbivory*. Nevertheless it was not an all together unpleasant experience, like that of an appreciation for chilli.
So naturally the bushfood product sold in Australia, is marketed as a native pepper produced from drying the leaf and berries. (7) Interestingly enough, the oil extract has been imported to Japan where it has been used for flavouring in wasabi paste, candy and chewing gum. (3)
The genus Tasmannia has total of 50 species occurring from Malesia to the eastern states of Australia with eight species endemic to Australia. (3)
*The ‘pepper’ taste contained in the foliage and fruit is a secondary metabolite, a compound called polygodial, which has been found to be antimicrobial and an insect antifeedant. (5)
In the Garden
The glossy foliage and red branchlets make this an attractive shrub in a shady part of the garden. (8) The plant responds well to pruning and is easily maintained. Soils need to be moist but well drained and mulching is highly recommended. (4) Mountain Pepper is not very well adapted to overly dry conditions being of an understorey species evolved in cool temperate forests and woodlands, so it requires regular watering, however avoid overwatering to curb the chances of root-rot infections. (4)
Mountain Pepper also grows well in pots. I suggest you establish the seedling in a larger size pot to avoid re-potting later on down the track, as it doesn’t cope well with being transplanted. (6)
Pic. In my backyard in Brunswick I have this Mountain Pepper growing in a 16 inch terracotta pot, with a vigorous ground-covering of Kidney Weed (Dichondra repens), another cool-temperate Victorian native at its base. I had recently pruned it back a little and as a result, numerous new branches of fresh foliage have arisen on the charismatic red branchlets. Photo: Nick Moore.
If you’re keen to grow the plant for the pepper berries you’ll need a female plant to bear the fruit but you’ll also need a male plant in close proximity to pollinate the female flowers. This is easier said than done I’m afraid, as there’s no way to tell with juvenile plants what sex you’ve got. If you do happen to grow specimens that bear pepper berries, you are likely to attract birds into your garden and this is actually how the plant is dispersed in the wild by birds such as the Green Rosella (Platycercus caledonicus) and Black Currawong (Strepera fuliginosa).(7)
