The pretender

Lobelia gibbosa – False Orchid

“It’s summer, and not a lot of orchids are about, but wait, who is that pretty blue flower over there?  Is it an orchid?  I’ve never seen it/read about this flower before.”

Lobelia gibbosa

It might be a pretty flower that is fairly easy to stumble across in the bush, but sadly it is not an orchid, and many have confused it as an orchid, thus enabling it to gain the name “False Orchid.”  It is not even a lily, but is in the family of Campanulaceae.  Since I do not know a lot of information about this plant, I’ve been doing some research and it is really a fascinating plant!

There are several reasons why it can never be an orchid.  It is an annual and orchids are not annuals.  Although the flower may look like it has five segments, it does not have the distinctive column found in all orchids.

DSC03004a (2)It generally has two to four purple/blue and sometimes white flowers that grow from a maroon coloured stem.  The flowers may have a stripe down the center of the petals.  Flowering begins in early summer.  Interestingly, at flowering time, the plant’s leaves have begun to die down.  The plant no longer depends on its roots for survival and can be uprooted and continue to grow.  Consequently it is one of the few flowers that can be found following a 40C heat wave!

It is a fairly widespread plant and can be found in all the states of Australia and even as far as New Zealand and South Africa.  It prefers a slightly open area for growth and seems to be able to cope with a variety of weather conditions.

So while it is not an orchid, or even a lily, enjoy it as it is quite a nice flower!

Victorian Orchids

South Australia is the only state in Australia that does not have any epiphytic orchids.  Our state is the driest state in Australia and does not have any rainforests that could offer a suitable condition for them.  So here is a video about some orchids that grow across the border in Victoria.

In Summer…

After having four consecutive days of over 40C (104F) heat, I’m pretty sure that there are not many orchids left in flower now.  However a weeks ago, the hyacinth orchids were in full glory.  Dipodium roseum is one of the most photographed orchids in Australia.  It is often found on road side edges which makes it easy to spot.

Dipodium

It is one of the largest terrestrial orchids and can grow a few feet high.  It grows around Stringy Bark trees as it needs a special fungi to survive as it has no leaves.  Can you spot it/them in the picture below?

This particular species is distinguished by having stripes (rather than spots) on the labellum.  The flowers vary from pink to a soft white, and can be growing on either a dark stem on green stem.  Personally I prefer the pink flowers on the dark stems and sometimes seem to forget the other variety.  Here are two variations growing together.

Some of my favourites

So I’m back!  I’ve enjoyed having a break from blogging while my non-orchid life has been busy and full of pleasant surprises.  Anyway it has been lovely to see that people are still looking at this blog, but I do feel a bit guilty for having not posted recently.  I’ve heard from others that they know someone who reads this, and I find that really nice to know that I make others happy by sharing orchids.  Please say “hi” and let me know where you are.  I would love to hear from you all.

So for today’s post, I’m just going to re-share a few of my favourite pictures from this year.  I did not get out as often as I would have liked, but I always looked forward to hunting for orchids.

Eriochilus cuculata (1)

First off we have Eriochilus cucullatus.  A friend told me about a lovely patch of Eriochilus cucullatus and gave me the coordinates to find the colony.  There were well over a hundred plants scattered across quite a distance.  I really like this pictures with the pollen sitting on the labellum.  I still don’t know how the pollen arrived there.

Fungi

In June, my digital camera tricked me into believing that it had stopped working which worked out very conveniently because I was able to upgrade to a digital SLR camera with multiple lenses.  It’s been great fun to learn to use it properly.

Pterostylis curta

The picture above was lots of fun to take.  The orchids are in a pot, and I set up the camera on the tripod, and zoomed in from a long way away.  The picture was actually taken indoors with the window to the front garden as the backdrop.  There was just enough afternoon sun to capture the golden colours.  This image has not been edited.

Arachnorchis rigida

I was really excited to see the Arachnorchis rigida this year, after not having seen it for awhile.  I love the crispness of the flowers.  At this point I had not learnt how to colour correct the camera so there is too much blue, but I think it kind of worked for this picture.

Arachnorchis tentaculata

Eventually I learnt how to colour correct.  The bush does have a beautiful golden colour which I feel has been captured in the above picture.  I did not realized that these two spider orchids had different coloured stems until I was looking through my pictures later.  I took this picture when I was planning to photograph a field of cockatoo orchids.  That day we were expecting a storm, and thankfully I was able to take my pictures before the wind had picked up and while the sun was still out!  Below are the cockatoo orchids.

Glossodia major

While the field was still spectacular, many of the flowers had already finished.  Maybe next year, I can catch them earlier.

Caleana major

Everyone’s favourite, the large duck orchid.

duck orchidThis year finished by seeing both the duck orchids.  These are always a favourite and every year I seem to forget that they are smaller than I think!  The whole flower of the small duck orchid would be less than 1.5cm high.  I particularly like how these two small duck orchids turned out.

Below is a gallery of other pictures that I enjoyed taking.

Orchids in the forest

Forestry SA land has some of South Australia’s most beautiful and exquisite orchids growing on its lands.  While it is predominately focused on pine tree plantations, it does recognize the importance of conserving our rare and beautiful orchids.  Here is a short film by Julian Pitcher, from Victoria, sharing his finds on Forestry land from a few months ago.

The small ducks came out a week or so after filming.

Enjoy.

Nice and Close

Its nice that I am discovering more features on the new camera, or rather my very kind brother is showing me them as he finds them.  Anyway, three weeks ago when I photographed the Arachnorchis rigida, I felt that the pictures had way to much blue in them.  Since then, I learnt how to adjust the white balance, and so now the pictures are closer to the true colours.

Arachnorchis tentaculata

I love this picture of these two spider orchids, Arachnorchis tentaculata, which are hugging each other.  I did not realize that they had two different stem colours, until I looked at the photograph.  Interestingly, the digital camera did not show this as vividly.  Below is another view of the same two orchids.

Arachnorchis tentaculata Another orchid that I saw recently was of the Purple Cockatoo Orchid, Glossodia major.  There was a lovely patch of well over a hundred plants.  I had first found this patch while all the orchids were in bud, but when I went back two weeks later, more than half had finished flowering.  This species has a lot of diversification in colour from a deep purple right through to pure white.

Enjoy your weekend!

A beauty

A couple of posts ago, I mentioned that I wanted to see some Arachnorchis rigidaI was able to do this last week, and they looked as beautiful as ever.

Arachnorchis rigida

These orchids are quite small as can be seen in this picture.  There were fourteen plants in flower with two in bud.

Arachnorchis rigida

There were quite a lot of other orchid species that I saw both in bud and in flower.  It was a very good site, and I am looking forward to heading back soon to get some more photographs.  Have a good weekend.
