Kidney Weed - Dichondra repens (Convolvulaceae)

Kidney Weed 
Dichondra repens (Convolvulaceae)


Dichondra: Two-lumped; refers to the two-lobed ovary
repens: creeping (stoloniferous)

Description: Prostrate, creeping herb

Habitat: Occurs in a wide variaty of vegetation community types; plains grasslands, Red Gum Woodland, Coastal Banksia Woodlands, riparian scrub and woodland, dry and valley sclerophyll forests, grassy lowland open forests

 

Distribution: Queensland, New South Wales, Victoria, Australian National Territory, Tasmania, South Australia, Western Australia and also New Zealand

Plant size: spreading habit so size is relative to growing conditions; the petioles (leaf stems) vary from <10 mm to approx. 14 cm


 Foliage: Reniform (kidney-shaped) to 40 mm long.(1)


Flower: Minute and greenish; flowering September to December.(1)

In the garden: Adaptable to a wide range of conditions; full sun or shade, will creep through lawns and grassy reveg, a good lawn alternative in light traffic areas.(1) 

This is an awesome potted specimen, as a base plant to a small tree or shrub or on its own. The one I have is in a large pot has been vigorously growing for over two years, forming a cascade of foliage spilling over the sides of the pot (would be great in a hanging basket) which forms the base to a Mountain Pepper (Tasmannia lanceolata) (see previous post). Summer watering in this situation is essential.

Victorian Christmas Bush, Mint-bush - Prostanthera lasianthos (Lamiaceae)

Victorian Christmas Bush, Mint-bush 
 Prostanthera lasianthos (Lamiaceae)

Prostanthera - from Greek words meaning appendage and anther, referring to the structure of the stamens;
lasianthos - hairy flowers

Description: Glabrous, compact tall shrub or upright small tree

Habitat: Shaded gullies, wet, damp and valley sclerophyll forests, lowland to subalps

Sticky Everlasting - Xerochrysum viscosum

Sticky Everlasting 
 Xerochrysum viscosum (Asteraceae)

Xerochrysum - from Greek xeros meaning “dry” and chrysos meaning “gold” (this refers to the common yellow papery bracts that occur within the genus)
viscosum - from Latin viscosus meaning “sticky” (refers to leaf character)

Location: La Trobe Wildlife Sanctuary

Description: Much-branched sticky biennial or perennial herb, dense or straggly

Habitat: Dry sclerophyll forest, red gum and box woodlands, often on shallow stony soils


Distribution: Queensland, New South Wales, Victoria, Australian National Territory and Tasmania


Plant size: 0.5-0.8 x 0.3-1 m

Foliage: Linear dark green leaves to 90 mm long, margins recurved

Flower: Compound flowerhead with whorls of papery bracts giving the appearance of radial petals. (1)

   
In the garden: It has been recommended that for a more compact growth, one needs to prune this species which as an added consequence prolongs the life of the plant. (1)

Matted Bush-pea - Pultenaea pedunculata (Hook) (Fabaceae)

Matted Bush-pea
 Pultenaea pedunculata (Fabaceae)
                                                                                                                     
Pultenaea – named after the English botanist Richard Pulteney (1730 – 1801). 
pedunculata – “with a flower stalk”, from the Latin pedunculus , meaning “a little foot”, and the suffix -atus designating the possession of something: the flowers of this plant possess a peduncle (flower stalk).

Description: Matting, prostrate perennial herb

Habitat: Dry sclerophyll forest, box ironbark woodland

Distribution: Victoria, Tasmania, New South Wales, South Australia


Plant size: Prostrate x 1-3m.

Foliage: Tiny, flat, dark green elliptical leaves to 12 mm long, hair below, margins sometimes recurved. Stipules prominent, 2-3 mm long.

Flower: Masses of single yellow and red axillary flowers on long hairy stalks; October to November (although I have seen it flowering till late December). Fine, long bracteoles.



In the garden: Well drained soils, tolerating dry periods once established. It grows particularly well as a rockery plant, with cascades of matting, dark green foliage. This makes collection of seed much easier as the drying pods are quite small (5 mm long) and only contain 1-2 seeds (they are easily lost once released). As a groundcover, grows well in between grasses such as Rytidosperma setaceum (R.Br.) (syn. Austrodanthonia setacea) or a base plant in large pots with other plants.

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)
