Native Plants and gift cards for sale

We will have our limited range of locally-native ecosourced plants for sale beside the Strawberry Stand as and when possible from now until Xmas, but the roadside is often crowded, and/or too hot for the plants and myself, so if you would like to buy plants via email we can arrange to deliver them to the Eskdale Reserve roadside, or you can pick them up from our little nursery in Windy Ridge.

We also have for sale ten gift cards (with envelope), for our popular Garden Ecology Assessment by appointment at the recipient’s home, including plant identification and advice on chemical-free weed control for your property.

Plants available for immediatel sale include:

Native sedges, or “grasses” as they are often referred to, popular in landscaping and ideal for absorbing heavy rain and preventing erosion, are hardy and self-maintaining.

Carex flagellifera from $3 each or 10 for $25…

….in 8cm pots for $5 each or 10 for $40 ….

Here are some of them lined up in front of Grandma and Grandpa, who are about 80cm high.

Carex flagellifera multiply both through division and by seed.

as do Carex lambertiana, a more compact plant with stiffer leaves and dark seedheads.

Kawakawa

We always suggest planting kawakawa in partial to full shade, keeping soil moist in summer, and buying a few to ensure having both a male and a female tree.

$5 each for 10cm pots…

8cm pots from $3 each or 4 for $10…

…or $10 each in 1-2L pots

Fuchsia procumbens / Scrambling Fuchsia – a pretty little creeper with tiny “ballerina” flowers to look out for in summer (but there are none on this young plant yet:) These Fuchsia plants are not ecosourced, but it is a locally native species)

We also have a few native trees , shrubs and ground covers of various kinds, including karaka, mapou, totara ti kouka, karamu, houpara and the tiny native sedge Carex inversa, which is good for filling cracks with its spreading rhizomes that help keep out the less attractive wildings such as dandelion, dock etc.

New life every autumn, including Kauri seedlings

Autumn and winter are my favourite times for restoration work. Everywhere native tree seedlings are popping up and, if recognised and protected, extend the wild habitats they spring from.

Manuka seedlings arise in bare sun-exposed clay, or as below, in manuka leaf litter on the outer edge of manuka “scrub”:

Karamu are abundant anywhere blackbirds visit

Totara, houpara and mapou appear under trees and among tall leafy plants (including weeds). These two mapou are under a mahoe tree

and occasionally, even in highly landscaped gardens within bird-reach of a forest fragment, we find the fern-like tanekaha seedling.

Tanekaha seedling in manuka scrub

The tanekaha below is probably 2 or 3 years old, (with two little karamu seedlings above it).

Tanekaha seedling in manuka scrub

On the edges of kauri forest fragments, kauri seedlings are scattered wherever the surface layer of humus (rotted leaf litter) has lain undisturbed for several months.

This one is no surprise – in a deep bed of leaf litter beneath a kauri and a tanekaha. You can see the smooth shallow hollows in the scales of fallen kauri cones that fell here, (as well as the frilly-edged stem-tips of tanekaha – which we usually refer to as leaves, though they are technically not leaves but stem-tips) (For extra points, spot the two tiny green kawakawa seedlings:)

But kauri can germinate in many types of surface, even bare clay after construction, esecially if there is a bit of organic debris to feed and shelter them.

It’s hard to believe that each giant kauri tree in our remaining forest fragments grew from simple and unassuming seedlings like these.

Even more gratifying to see a kauri seedling appear this autumn in the space between rotting wild ginger tubers! (No chemicals used, no digging or yanking, just our fold-down technique that rots the whole clump out over a few years).

Kauri seed (lower) with karamu seedling (upper)

I have seen dozens of kauri seedlings appear each year in a few metres of partly shaded lawn in a garden bordering a kauri forest reserve…. to be either mown to maintain a lawn, or weeded carefully and supported with other native regeneration, to begin a new little patch of forest.

In Gahnia Grove in Eskdale Reserve, a single kauri seedling appeared in 2020 under a small shrub (a planted Cook Island Flax) only 2 metres from the mown playing field on Glenfield Rd.

July 2020

The nearest kauri old enough to bear cones is about 100m away from this seedling.

July 2021

Weeding continues to protect this kauri seedling, and the native plants that nursed it while it germinated are pruned to give this enterprising kauri seedling ongoing space, shelter, light and protection from human activity.

Book a private or group assessment if you would like the hidden or unrecognised native plants revealed and identified in your garden or Reserve.

For neighbourhood groups restoring their local Reserve, it is essential to do this assessment both before and throughout planning or undertaking weed control, because without thorough knowledge of the existing habitat, more wild native vegetation is likely to be lost during weeding and planting than can be successfully established by planting.

The same applies to home gardens, where free native plants can save a lot of money!

Collecting questions at the Plant Stand

At our winter plant stands on Glenfield Rd last year we enjoyed answering many questions about how we restore wild native plant communities (eg Gahnia Grove in Eskdale Reserve, where we hold the plant stands).

It takes more than a few minutes to answer such questions fully enough for people to be able to manage their own weed control using this method of plant identification and hand weeding.

To help meet the demand for more teaching and demonstration of the techniques and strategies we use, we have asked a friend to collect your questions and areas of interest, so we can answer your questions through demonstration and illustration in a co-ordinated way.

We will both be at the Plant Stand (opposite the petrol station on Glenfield Rd) from 11.00 am to 12.30pm this Sunday.

Meanwhile, our usual small range of locally ecosourced native plants will be on sale until about 3pm, weather permitting.

Moss Island

Moss Island, October 2024
June 2019 – Old rubbish collected from the forest as part of the Gahnia Grove restoration project is piled beside the orange tape, marking this extension of the Gahnia Grove chemical-free weed control trial and restoration project.
The weedy grass area on the left was later cordoned to become part of “Cherry Bay”, and in late 2020 Moss island was created there.
Cherry Bay in July 2020. Moss Island was created later that year, in the area of grass behind the cordon, between the foreground and the big clump of harakeke.
Cherry Bay is the whole area behind the cordon on the right, visible from the lower right-hand corner of the upper field of Eskdale Reserve in Glenfield Rd
July 2020: The grassy area to the left is where Moss Island was later created. The lower trunk of the big cherry tree can just be seen on the far left of the photo.

In 2020 during Auckland Council’s construction of a new forest track for cyclists and pedestrians, we asked their contractor RAM Contracting if they could save a little of the beautiful moss-covered clay bank which had to be excavated to widen, pave and channel the track for its new use.

Native mosses, shrubs, creepers, fungi and tree seedlings lined the old forest path along the top of the ridge

The RAM Contracting team kindly agreed, and brought a digger load of large clay pieces out of the forest to the edge of the playing field below Glenfield Rd.

At our request they placed the pieces together in “Cherry Bay”, a damp weed-grass covered area just behind the Gahnia Grove cordon (see photos at top of page), where we could weed around it a few times a year while observing what happened to its covering of native mosses and gum-lands tree and shrub seedlings.

Below, some close-ups of Moss Island in March 2021.

Moss Island after the summer: Milk moss, with seedlings and young tangle fern, mingimingi and tanekaha, and a little invasive Creeping buttercup creeping in from the surrounding “weed sea”.

The big vine and shrub weeds and most of the tree weeds had been manually controlled in Cherry Bay in 2019, and wild revegetation was progressing well, but this particular part of it had little shade overhead, and gets very wet in winter, so it fills with Creeping buttercup and grasses every autumn.

The buttercups creep into the mossy clay and are weeded out by hand, and the “sea” of weeds around the “island” of native forest, so we keep the weeds down with a heavy mulch of dead wood, cherry and harakeke prunings, pine litter from under nearby pines, and any weeds that can be easily uprooted or cut down around it.

A mulch of Harakeke prunings helps suppress weeds in Cherry Bay
Moss Island in July 2021, the area around it recently weeded and mulched with woodchips (by the cordon) and harakeke prunings (under the trees)

As expected, the larger tree seedlings growing in the clay pieces died not long after, but the native “milk moss” (Leucobryum javense) and many of the native tree and shrub seedlings are thriving, four years after translocation of their clay bed.

We are grateful to RAM Contracting for their understanding of and collaboration with the Gahnia Grove restoration project’s objectives, and their cheerful contribution of time and equipment in creating Moss Island.

End-of-winter sale – Native plants half-price tomorrow on Glenfield Rd

Tomorrow, Sunday 1st September, we will be selling our remaining large Kawakawa and Carex flagellifera at half-price: $5 for the 12-15cm pots and $4 for the 10cm pots, at our native plant stand on Glenfield Rd opposite the petrol station….while stocks last.

Kawakawa fruit are a big drawcard for kereru. Male and female trees are needed for fruiting, and you can’t tell which is which until they flower at about 4 years of age, so plant half a dozen. They grow in sun or shade but do best in part shade, and need moist soil in summer. The kawakawa left of centre and on the right below are growing wild among Carex and other natives.

Carex flagellifera self-seed and multiply by division, filling a space to hold the soil and crowd out weeds . They are tolerant of dry or wet soil, in full sun or part shade. These have multiplied in a gap between harakeke on Glenfield Rd, and karamu are growing wild with them:

Pathside vegetation flourishing along the upper Eskdale Forest track alongside Gahnia Grove

Along the new track through the upper margin of Eskdale Forest, bare clay is turning to a variety of native plants, many of which only grow in kauri forest. These gracefully drooping young plants hanging over the edge of the track are Gahnia xanthocarpa, sometimes called “giant cutty grass”, a typical component of kauri forest where sun reaches the forest floor.

Almost impossible to propagate, they are so well-designed for the harsh environment of low-fertility kauri lands that they have sprouted up all along the exposed clay banks lining the track across the top of the ridge.

There are a few adult plants among them, their black seeds hanging from tall brittle stems.

To fully appreciate the value and beauty of this pathside vegetation, see the same bank below in November 2020 during track construction, when this section of rutted clay bank had suffered temporary loss of even more of its trees, shrubs, sedges, ferns, creepers and mosses.

In 2020 during track construction

Look for even greater beauty and diversity as the years pass. For example, tiny native orchids depend on the ground being undisturbed, as they only appear above ground during winter. Where old ground has remained undisturbed, they can be seen along the path on almost vertical banks, vitally protected by fallen ponga fronds and leaf litter caught in the undergrowth.

This Grass-leaved greenhood orchid (Pterostylis graminea), which we saw yesterday, has probably reached its full size at about 6cms tall.

Large Carex flagellifera for $8 at our Glenfield Rd Plant Stand

The North Shore Wilds native plant stand will be open tomorrow Sunday, opposite the petrol station on Glenfield Rd, from about 10am. Our larger plants need to be well rooted in damp ground before summer drought (unless they will be watered), so the largest Carex flagellifera have been reduced from $10-12 to $8.

Carex have long hair-like roots that penetrate and stabilize clay soils. Grown close together, in full sun or shade, they form dense hardy tufts that can be occasionally walked on, preventing soil compaction and erosion in wet weather.

Their seeds are the natural habitat for tiny… and harmless… native Carex beetles, which I have seen only a few times. I was amazed that this species had survived the 20 years since I sourced and planted these in my own garden.

Like most of our other plants, these are grown from seed ecosourced from the Kaipatiki area.

The photo shows three species of wild Kaipatiki-native Carex allowed to grow as they will, spreading to cover previously bare clay under a planted kawakawa and a wild nikau, in an 80cm wide strip of soil outside a dining room window that gives a great view of kereru feeding in the kawakawa in summer. (We still have small kawakawa trees for $3 each or 4 for $10.)

Our spaces are shrinking, but we can still have wild beauty !

Kawakawa “special” – small plants 4 for $10 today

Today at the plant stand on Glenfield Rd we have a “special” – 4 of the $3 kawakawa for $10. Kawakawa enjoy close plant communities and can be seen wild – or planted – in groups, under shade trees, and among other small trees and shrubs.

Having several of them gives you a better chance of having both a male and a female tree. Only the female trees will bear fruit.

Both male and female trees are needed for pollination of the flowers so they produce fruit. I dont know how near they need to be to each other. More info at northshorewilds.co.nz

Restoration planting… or wild revegetation… for water absorption and soil stability

Tomorrow, Sunday, I will be taking the North Shore Wilds baby plants (still priced from $3) for their weekly outing to Eskdale Reserve:). We will as usual be near the Flame tree opposite the petrol station. I will set up there every Sunday by about 10am, and maybe some Saturdays, through the planting season (or while stocks last).

We have had a lot of discussions there with customers, Reserve visitors and passersby, lately about landslips, natural overland flows, Kaipatiki’s many named and unnamed streams (including those that only flow in winter), and how to deal with seasonal excesses of water in the garden.

Auckland Council has lots of info about “greenfields” stormwater management and the restoration of dense vegetation to absorb water and stabilize soil. Recently I read a study which found that ti kouka (Cordyline australis, cabbage tree) is particularly good at this job. Its roots grow quickly and deep, it doesn’t mind “wet feet”, and it is a fast grower.

It also attracts birds, including kereru, to its huge bunches of glossy black fruit.

You can easily raise as many ti kouka seedlings as you want, merely by refraining from spraying, mowing or disturbing unused ground, identifying everything that comes up, suppressing problematic weeds, and supporting the ti kouka seedlings with a mulch of anything around… which includes most of the weeds you have pulled out or squashed down.

See what a good job the ti kouka and karamu are doing around the plant stand in Gahnia Grove! Road runoff pours down this steep bank, but the trees are absorbing the impact of the raindrops, drawing a lot of the water down into the ground for storage till they need it in summer, and holding the soil together. The dense ground covering vegetation further softens the impact of the rain, preventing loss of surface soil.

Groundcovering plants here still include some of the remaining harmless wildflower weeds, which we maintain for this purpose until they get shaded out as the young trees become dense.
