Sparkling raindrops

We have had a lot of rain.  A lot.  Most plants are thriving, drinking it up.  But this weather can get tedious - grey and heavy.  However, there has been a "silver lining" - sparking silver raindrops on the feathery foliage of fennel...

and on the rich reds of the smoke bush (Cotinus).

And today we enjoyed bright blue skies and warm sunshine.  Hopefully there is more to come!

Christmas-y colours of spring - Kaka beak, Clematis Sweet Hart

Well, it must still be spring - the weather here in Wellington remains capricious and, frankly, not all that pleasant.  Gales have been blasting tender new growth and the southerlies keep bringing the temperature down - to cold.  

But summer and Christmas are coming.  Here's to the bright colours of early spring - seen in the Christchurch Botanic Gardens - and the coming festivities:

The red and green of Kaka beak (Ngutu kaka)

 And the brilliant white of Clematis Sweet Hart, a hybrid native clematis. 

These were in flower a month or so ago, but I remember them fondly amidst the red, green and white Christmas decorations that have been proliferating for weeks.

A winter treat - sunshine and Monarch butterflies at the Wellington Botanic Garden

Wellington on a good day - no wind, sunshine, and signs that spring is getting closer - what could be better!   Well, a walk in the Botanic Garden and a visit to the scented garden made it better still.   On the grassy hill by the Treehouse visitor centre, early Narcissus - white and yellow (probably N. tazetta) - are already blooming brightly.  But what were the flashes of orange that I saw?

Monarch butterflies were feeding and flittering and chasing each other and resting in the sunshine.  Evidently they have been overwintering here.  After the cold, rain and gales of the previous week, they appeared to be making up for lost time.  Alas, I was not equipped to photograph the ones on the wing, but I happily photographed some of the butterflies more intent on feeding.  These ones on a camellia bush were so settled they looked more like colourful flowers.

There was quite a choice of flowers for a hungry butterfly - yellow wallflowers,

pale purple wallflowers,

or "yellow daphne" - Edgeworthia chrysantha also known as oriental paperbark,

not to mention heliotrope, daphne and other scented lovelies in the garden.  The butterflies' wings looked a bit weatherbeaten, but they were still a magnificent sight.  And the scented flowers were a treat for me too.

Caught in the act - kereru (NZ pigeon) scoffing horoeka berries

I love pathways that get you up high and close to trees.  I was on one at the Arataki Visitors Centre in Auckland's Waitakere Ranges.  There you have a great view sweeping across bush towards the city and the Waitemata and Manukau harbours.  And there is a walkway that threads around some mature trees. 

As I walked along it I heard an odd sort of scrabbling sound coming from one of the trees - a horoeka or lancewood (Pseudopanax crassifolius).   At first, there was nothing obvious to see - but then I caught a glimpse of large red claws, white feather pantaloons, and a back with purplish-green feathers.

A kereru (New Zealand pigeon)!  It's a large bird - weight around 650 grams, length 51 cms - so an awkward size for the rather slender branches it was perching on.  But the numerous berries were obviously of interest. 

It struggled a bit to get to them, and some gymnastics were required - stretching and balancing.  But it was intent on scoffing those little berries. 

The kereru is a frugivore - a fruit eater - but will also eat flower buds and leaves, depending on what is available.  With its big bill it is able to eat the large fruit and drupes of a number of native trees.  The flesh of the fruit is digested, but the seeds are not.  The subsequent dispersal of native tree seeds in pigeon poo, and thus native forest regeneration, depends on the kereru.  Drupes are stone fruit with flesh surrounding a seed protected with a hard shell - like a plum.  And alas for people growing them, the kereru apparently does like the plum.  

The kereru is just one of a number of native birds that disperse horoeka seeds - even the little silvereye can eat the small berries.  So the horoeka does not depend on the kereru.  I daresay smaller birds would cause less kerfuffle when they are feeding on the horoeka too.

Maybe it was a bit big for its perch, a bit clumsy in its maneouvres on the horoeka tree.  But what a handsome sight the kereru was as it emerged to inspect me! 

Golden ginkgo in Cornwall Park - autumn colour in early winter

Autumn colour!  A lovely surprise on a brief visit to Auckland, where it is warmer and much less windy than Wellington.  It is considered early winter now, but the leaves were holding on.   A particularly dazzling display was in Cornwall Park - a grove of ginkgo trees planted in the 1960's.  I caught them in a moment of quiet.  People had been photographing, playing with the leaves, gazing and otherwise enjoying these wonderful trees. 

The trees look quite small in the photo above - but this was taken from a small hill beside the trees, and with a wide angle lens.  In fact, they towered over us.

While this grove is old it is certainly not ancient, but the ginkgo (Ginkgo biloba) is an ancient tree - the sole survivor of a group of trees older than the dinosaurs.  It is regarded as a "living fossil."

Young trees have a more regular shape, but these branches seemed to swirl and tangle.

The bright green of summer leaves is gradually replaced by the bright yellow of autumn. 

Looking up you can see smudges of green remaining at the base of the fan-shaped leaves.  The similarity of the leaf shape to the maidenhair fern led to the ginkgo also being called the maidenhair tree.

It is a remarkable tree, beautiful, disease and pest resistant, very long-lived (the oldest is said to be 3,500 years old) and tolerant of quite poor conditions and pollution - here in Wellington it is a street tree in parts of the central city. 

What these trees have been through - from dinosaurs to fossil fuel-consuming monsters!

Orca excitement at Owhiro Bay

On an errand, and heading towards Owhiro Bay on Wellington's south coast, I was surprised to see people on the beach - it's winter, and the cold wind means it is not a pleasant place to linger.

As I drove closer I saw a large body swimming close to the water's edge.  The impressive dorsal fin explained the excitement.  By the time I had stopped the car there was nothing to see at the beach, but people were perched on the rocks opposite, and others were walking and running along the road, heading along the coast.

This is what the excitement was about -

Three dorsal fins - orca (killer whales) were swimming along the rocky shore.  Someone said there were five altogether - tantalisingly close but elusive.  It was really difficult to catch the moments when more of their bodies were visible.

They were swimming around the rocks - so near and so far.  Their movements were so smooth, they moved so fast!  There were cameras and phones aplenty in action as people attempted to capture their sightings.

This gives some idea of scale.

These are large impressive beasts, and there was a happy buzz of excitement among the people who ran, clambered and stared, all for momentary glimpses.

Well, I didn't get any good photos, but I hope that these snaps convey some of the awe that is available to us, and that many people respond to so readily.  We are so very lucky in Wellington to be visited by orcas

World Oceans Day (8 June) has just passed, and the news we get about what is happening to the oceans is very disturbing - the water temperature is rising much more quickly than was projected, and the impact on life in the sea - these vast expanses of water that make our planet so distinct - is being profoundly affected.  Many of us are moved by the life that is threatened - excited, impressed, delighted, curious, fascinated.  I hope that these orca visits help us also to be very active in respecting and caring for the quality of the oceans and the precious marine life sustained by them.

A summer treat - watching the Monarch butterfly life cycle

After a grumpy windy start our summer was warm and settled and as a bonus there was an abundance of butterflies.  In addition to swarms of cabbage whites and lots of yellow admirals, there were quite a few Monarchs, and this year we had swan plants for the fussy caterpillars - they only eat milkweed and the swan plant is the one that they feed on here.  It's the one garden plant that people grow just for it to be eaten by caterpillars! 

The Monarch butterflies would flit quickly through the garden, feeding and depositing eggs.  They were hard to catch in the act, but here is one - you can see another was there before her.

A Monarch egg is such a tiny dot on the leaf.

Soon a glimpse of black appears - it is the head of a caterpillar about to emerge.

Teeny tiny and hungry - at first the little larvae/caterpillars nibble on the leaf undersurface.

They start growing and moving,

and eating till they need to shed their skin in order to grow. The moult reveals the next stage (instar) - the distinctive yellow stripes and little feelers are beginning to show.

Onwards they go, consuming the tender new leaves of the swan plant, but graduating soon to larger ones - there's a long way to go to get up to big brother/sister size,

shedding skins to make room for the rapid expansion,

when the leaves are gone, eating the stems, until it's time for the almost magical change. 

Time to attach itself - hanging in a J-shape,

it sheds its skin, changes shape and colour,

making a beautiful green chrysalis,

maturing, (here decorated with raindrops)

emerging,

pumping up its wings,

leaving a shell behind.

I had to get more swan plants to manage the hungry hordes, and did so with pleasure.  Favourite surprise - the way the little tentacles/feelers on the caterpilars wiggle while the caterpillar is eating - very expressive. 

The last butterfly to emerge was just ahead of the cold snap that announced the end of summer.  Monarch butterflies overwinter in warmer areas of the country.  In the northern hemisphere they manage to fly from Canada to Mexico to overwinter, so there is some hope that even the last Monarch that emerged in our garden managed to escape from our wild south coast.

Fun with plants - fantastical topiary at Royal Botanical Gardens, Melbourne

For the child in all of us, and a happy reminder of spring in Melbourne - lush greens and fantastical creatures by the entrance to the Ian Potter Foundation Children's Garden in the Royal Botanical Gardens.  The topiary shapes were (I think) made with Muelenbeckia complexa or pohuehue - our somewhat unruly, potentially invasive and very determined native twining plant sometimes known as wire vine.

The backlighting emphasised how they were due for a haircut!

The magnificent kauri - Agathis australis - a taonga that needs more treasuring

The New Zealand kauri is a magnificent tree, one of the largest and longest growing trees in the world and the oldest in New Zealand, appearing here 20 million years ago.  Tane Mahuta is the name given to the largest surviving kauri.  It is 45.2 metres tall, with a girth of 13.7 m.  Its trunk is unbranched to 18 m.  The oldest survivor, Te Matua Ngahere, is thought to be at least 2,000 years old.  It is shorter and more squat with a height of 37.4 m and girth of 16.76m. 

Substantial!  (And phenomenal carbon sinks, a function that will be valued more and more.)   

Here is Tane Mahuta.  Unfortunately I did not have a person in front of it for scale.  To give some idea, the base of the tree is obscured by bush, and if you were able to get close you would be hidden by the plants in front.

Kauri are slow growing trees, gradually dropping lower branches and changing from a conical to a columnar shape with a flattened mop of branches at the crown.  Mature kauri crowns have huge branches which support an abundance of life with ferns, mosses, epiphytes and lianes.

Below we see the view up a smaller tree than Tane Mahuta.  It gives a limited idea of the scale of life supported by the crown.  People who study the ecosystems in the crowns need the skills of arborists and a head for heights.  There is a lot of life up there. 

But the future of the kauri is uncertain.  4 million acres of forest were here.  They have been reduced to 18,000 acres of forest with the vast majority of those trees having been felled or destroyed by European settlers from 1820 on, with surges of such destruction occurring in the late 1800's and 1920's to 30's.  Even as recently as the 1960's the government was facilitating logging of pristine kauri forest.  The wood is fine grained, hard, and beautiful.  Because the trunks are straight and unbranched to a considerable height, kauri were valued for use as masts and spars for sailing ships.  You would think that such special timber would be valued.  But it was wanton destruction - about half of the enormous volume of timber from the felled trees was burned. 

Now the kauri is threatened by kauri dieback a disease specific to New Zealand kauri, caused by Phytophthora agathidicida.  It kills kauri trees, and it is untreatable and spreading. 

What are we doing?  On one hand there are efforts to stop further spread of the disease - eg protection of the vulnerable roots around those trees that we visit to admire, special walkways and stations for cleaning shoes to stop the spread of the infection.  And on the other hand, there has been a weakening of the law that identifies trees that should be protected.  So an apparently healthy urban kauri growing in an area where dieback is present had no protection when the people who bought the land on which it grew sought permission to fell it and other substantial trees, in order to build a house.  If it has resisted dieback it is very precious and may help the fight against the disease.  Too bad - concern and protest and occupation by tree-sitters delayed but did not stop the destructive intent of these people.  It has been ring-barked - a cruel injury which means there is little chance that it will survive. 

So, wasteful colonial attitudes do seem to persist to this day.  And a government which removes protections previously in place for such trees seems like a blast from the past too. 

We are so small - on this walk in Waipoua Forest it is the smaller trees and understory that dwarf the walkers.

And yet our carelessness and lack of foresight might mean we lose this taonga (treasure), the kauri.

We humans are a puzzling lot.

Thalictrum kiusianum - Kyushu or dwarf meadow-rue - one of my tiny treasures from Hokonui Alpines

Apparently we have a limited supply of willpower each day.  In New Zealand we also have a limited supply of specialist plant nurseries - many have closed over the last twenty or so years.  So there is a shrinking list of plants available to buy.  The vagaries of garden fashion are partly to blame but, more importantly, fewer people have the time or interest for gardening.  However, a recent development is the increased interest in growing vegetables and fruit.  I think this is great for many reasons, and maybe it will be the gateway for more people to discover other horticultural delights.

But I need no encouragement - I am very susceptible to the lure of almost any plants!  And Hokonui Alpines have a good catalogue, often refreshed with new and intriguing additions.  So especially in times of will-depletion I find the catalogue quite irresistible, knowing that they offer plants not available otherwise (and that they are so friendly and helpful and provide such good plants.)  I succumbed recently and was delighted to receive a box of plants from them a few days ago.

Thalictrum kiusianum, known as Kyushu meadow-rue (it is native to Korea and Kyushu, Japan) or as dwarf meadow-rue.  It is a low growing (up to about 15cm or 6 inches high) groundcover from moist woodland alpine areas, conditions I must now try to emulate.  It makes a mat of little leaves that look quite like the leaflets of a maidenhair fern.  Above the midgreen leaves, tiny starry flowers are clustered on slender stems giving a light airy almost fluffy impression.  It looks delicate, but I hope that it will live happily here.
