Success in saving rare spider orchids

Any orchid expert will tell you how hard it is to germinate the seeds.

Yet, two threatened Australian native orchids have recently been germinated symbiotically for the first time.

They are the Crimson Spider-orchid (Caladenia concolor) and the Sand-hill Spider-orchid (Caladenia arenaria), from New South Wales.

The exercise is part of the Australian Network for Plant Conservation’s (ANPC) Orchid Conservation Program delivered with the Wimmera Catchment Management Authority (WCMA) in Horsham, Victoria.

All Australian terrestrial orchids rely on a specific mycorrhizal fungi to germinate and sustain their growth throughout their lifecycle. Researchers needed to find the right type – and they finally did.

To further complicate things, each species is pollinated by a unique insect. They don’t yet what pollinates the Crimson Spider-orchid, but interestingly the orchid has a distinctly mandarin flavoured smell.

The Crimson Spider-orchid is particularly rare, with fewer than 30 plants in the world in an area confined to granite ridge country near Albury, and is also found in north eastern Victoria.

Orchids back on track

Orchids and railways don’t mix.

In the late 1800s, when railroads first arrived in Florida, the plants were among the first resources exploited. Literally millions of orchids were picked to be despatched north as potted plants. Now, after more than a century of logging and harvesting, it’s rare to find them growing in the wild.

Researchers at Fairchild Tropical Botanic Garden hope to change that with their Million Orchid Project, encouraging flowers to bloom amid the hustle and bustle of city life.

According to a heart-warming report, “the basic concept is to get these orchids out into the community,” says Carl Lewis, Fairchild’s director. “We’re trying to get them into some of the most population-dense urban areas here in South Florida.”

The plan will start with three orchid species, cultivating from seeds in the Botanic Garden’s micro-propagation lab.

Volunteer scientists and others with lab experience will grow the orchids from miniature seeds. Currently, there are racks upon racks full of bottles, each containing dozens of tiny orchids.

Transferring them from one container to another as they grow ‘is a bit like building a ship in a bottle’, which is a wonderful image. Volunteers use forceps to move each little shoot, one by one.

Later, the orchids are moved to a greenhouse. In time, and commencing this spring, the team will start inserting them into trees throughout Miami. The idea is based on a similar orchid project in Singapore. Not all will survive, but there are high hopes that some of Florida’s most beautiful native plants will return to the wild.

Dublin delight

Whenever I visit a new city, I make a point of checking out the botanical gardens.

It all started when I was researching orchids for The Lost Orchid, a Victorian botanical adventure.

In April, last year, I was lucky enough to get to Dublin - and I finally got round to making a small video

The gardens are a little out of the way, but worth the trip - a single bus from the centre.

The National Botanic Gardens were founded in 1795 by the Dublin Society. The fine Glasnevin collection number over 15,000 species from a wide range of habitats from all around the world.

The stately glasshouses are beautifully restored and packed with luscious plants. They stand in a massive plot, featuring herbaceous borders, rose garden, an alpine yard, pond (more of a lake), rock garden and arboretum.

Conservation plays an important role in the life of the botanic garden and Glasnevin is home to more 300 endangered plant species from around the world including six species, which are already extinct in the wild.

The poet Thomas Tickell owned a house and small estate in Glasnevin and, sold to the Irish Parliament in in 1790, and then given to the Royal Dublin Society to establish Ireland's first botanic gardens. A fantastic double row of yew trees, known as "Addison's Walk" survives from this period. The gardens were the first location in Ireland where the infection responsible for the 1845-1847 potato famine was identified. Throughout the famine, research to stop the infection was undertaken here.

And, of course, the orchids. Boggling. Take a look at a small video I put together: some uplifting spring sunshine and flowers from April 2013. Later, I'll share the delights of botanical gardens in Heidelberg, Amsterdam, Berlin, Edinburgh and Glasgow.

Zoom in on orchids

Orchids take centre stage in a new film called Darwin and his Fabulous Orchids.

It’s a polished nature movie about a naturalist’s journey through evolution, with the aim of introducing new audiences to the world of orchids in a novel and rather impressive way.

It is a ‘full-dome’ show that sheds light on their significance for Charles Darwin’s findings about the origin of species. Carl Zeiss has obtained exclusive distribution rights.

A joint production of the ‘Mediendom’ (media dome) of the Kiel University of Applied Sciences, the Botanical Garden of the Christian Albrecht University; and the Tilt Design Studio in Hamburg, it was supported by the Volkswagen Foundation and realised with assistance from German planetariums.

It represents a bid to enhance the aesthetic appeal of dome projections.

A total of 50 minutes in length, it is suitable for families, and features 3D computer-animated graphics in a new and engaging way. The trailer will make your head spin. It is in German and ‘English’, although the portentous voiceover may not appeal to all.

Rare 'lost orchid' discovered

One of the planet’s rarest orchids has been rediscovered in Scotland by the descendant of the plant collector who first found the bloom over a century ago.

Perth-born Bill McPhairson, great grandson of the famous Scottish plant hunter-turned-hybridiser John Telfer McPhairson, was walking his dog in local woods when he came across the scarlet and blue Pseudo-Phalaenopsis mcphairsoniana.

Like his father and grandfather before him, Bill is something of an orchidist and recognised the distinctive petals right away, with their striking striations reminiscent of the distinctive Kelt tartan.
