Plants of Ice & Fire

Plants of Ice & Fire

The Royal Tasmanian Botanical Garden

A few years ago I had no idea where Tasmania was.  I remembered the Looney Tunes ® cartoon character of the Tasmanian Devil, but beyond that I knew little else.  Until this year, when I found myself in the Tasmanian Royal Botanical Garden in Hobart, Tasmania, Australia, over 8000 miles from my garden.

Macquarie Island Cabbage

Botanical gardens are known for highlighting collections of plants from distant lands.  I regularly find the tropical plant collections in a glass conservatory in the cold winter areas, or an African collection in a desert garden of the southwest.  But in only one garden in the world is there a collection of plants that thrive in the icy temperatures of the  Subantarctic Macquarie Island, a tiny bit of land only 47 square miles, located 1/2 way between Tasmania & Antarctica.

In all the penguin movies and reports of explorations of the South Pole the image is always of snow, ice and rocky shores.  On Macquarie Island, seals, four varieties of penguins, and over 100,000 birds roost and breed.  A small area of the treeless island has hardy and important plants to support these animals.

In the Subantarctic Plant House, these grassy tussocks, ferns, mosses and lichens are on display.  The plant house imitates the conditions of the island with fog and soaking mists, and a temperature of 40 degrees Fahrenheit and below.  You can tour the entire display, all 46×20 feet, without donning a heavy coat. A sound track of bird calls, seals honking, penguins braying, howling winds and heavy mist adds to the experience.  A panoramic mural expands the sense of place with a view of the Southern Ocean.

Walking the boardwalk path in the plant house I was delighted to discover that there are red button blossoms on the silver leaf daisy (Pleurophyllum hookeri.)  There are six foot ferns and the Macquarie Island Cabbage (Stilbocarpa polaris) with its fuzzy green leaves once eaten by whalers to prevent scurvy.  Not currently on display here, the island also grows a Helmet orchid (Nematoceras dienemus).

Even here plants are essential for life! The Poa grass tussocks (clumping) provides transitory refuge for seal pups to hide out while they are adapting to seeking their own food sources. Birds use the plant areas for breeding and nesting.  Low growing mosses, lichens and Feldmark tufted grass holds on to thin volcanic soil.

The Subantarctic house opened in 2000 allowing a glimpse of plant life few travelers would ever see. Discovering plants from places where we don’t realize plants even grow illustrates the importance of biodiversity on our planet. No matter how far you travel there is always another place to discover just a bit further on. This display puts you there.

After we left the cold of Subantarctic  and returned to the spring sunshine in the rest of the garden we met a new flower, one that thrives after a fire.

Waratah Garden

Waratah Garden

The Tasmanian Waratah, (Telopea)  of the Proteaceae family, is native of Australia. It is a shrub that grows wild in the eucalyptus forests.  Waratah is an aboriginal word for beautiful and these are special flowers.  The single flowers on an upright stem are round and surrounded by what looks like petals.  The bloom is really a combination of florets which expand into squiggles (not a botanical term but look at the photo,:wouldn’t you agree? ) and stiff bracts.  Brilliant reds, deep pink, and white blooms attract the Crescent honeyeater bird and it sips the honey nectar pollinating the blooms as it moves from flower to flower.

The plant blooms for only five weeks in the spring, yet the beauty and long life of the cut flowers has made them of great interest to the floriculture industry.  Cultivation progress has been made and some, the Sydney and the Gippsland Hybrid, are grown in home gardens of Australia, but these are true wildflowers of the forest.  When fire burns in the Eucalyptus bush the Waratah regenerates quickly and in two years a valley can be filled with brilliant red flowers. The shrubs grow in poor sandy soils with regular rainfall.

These are only two of the wonderful features of this garden. You have a chance to see plants which thrive in the extremes of ice and fire. The Royal Tasmanian Botanical Garden was established in 1818 as a resource for food plants to provide for the growing English population of Tasmania.  Fruit trees, hops, turnips, potatoes and cabbages were some of the important plants first grown. In 1968 the garden celebrated its 150th anniversary and the anniversary arch stands in tribute to that event.

Today their vision is to be internationally recognized as a center of excellence in Southern Hemisphere cool climate plants.”  It is a truly spectacular garden but it gets very little mention in travel or garden guides!  So if you find yourself curious about Tasmania, a little dot of an island south of the Australian continent, they have a wonderful botanical garden.

Post Script:  About that Macquarie Island Cabbage:  In an Archive Article from the National Botanical Garden,  they were exploring the use of the cabbage as a possible food for contemporary tastes.  Records say whalers “prepared the plants by scraping the stalks and roots, chopping them finely and making a cabbage flavoured stew.

One account (Sinclair – 1877-78) describes Christmas dinner on Macquarie Island as consisting of :

“corned beef and an herb that grows here which we call cabbage, potatoes, elephant (seal) tongue, curried parakeets, penguins’ tongues, hearts and livers, which are first rate, preserved meat, a roly-poly made of blackcurrant jam”.

Despite such an exotic Christmas experience by a crew of sailors more than 100 years ago, Dawson says at present the Macquarie cabbage is not commercially attractive.” New taste sensations from the ‘down-under’ islands by Jan Smith, Dec. 24 1998

This has to be the most amazing Christmas dinner menu I have ever seen.

The Artichoke Project

The Artichoke Project

Late last November I planted two Artichoke plants in a sunny spot in one of my new flower beds. I wanted something to grow fast and add some variety of color and shape to my view. They grew beautifully! By March their silvery-green leaves spiked up vigorously at both ends of the bed providing aContinue Reading

Floriade Nightfest

 In ancient times much of the world paused in their work to celebrate flowers.  Weary of winter and with food supplies running low the Roman Goddess Flora was celebrated. In the spring a Maypole was erected, ribbons streamed down and the dancing began.  Young women wore crowns of flowers in their hair. The beauty ofContinue Reading

In September it is spring in Sydney Australia and when we walked into the 2.5 acre Chinese Friendship Garden for a moment I thought this will be the same as other Chinese gardens. There were the quite wonderful textured rocks and the bonsai collection in the entry but there was something more, the garden wasContinue Reading

Roma Street Parkland

It is said that great cities have great parks and as I travel I see this proved true again and again.  But I would add, great cities have citizens who realize the value of their parks and come to them to rest, relax, revive their spirits and reconnect to the important things in life.  HereContinue Reading

Some ideas take a long time to grow and The Oregon Garden is just such an idea. The Oregon Association of Nurseries had long wanted (since 1940) a demonstration garden to highlight the incredible variety of plants grown in the area.  Since 1968, the citizens of Oregon have been leaders in protecting the climate, air,Continue Reading

Sunflowers in Song

Sunflowers in Song

A single row of sunflowers is a delight in my garden!  As the flowers fade and seeds form a flock of yellow canaries and some peach faced loved birds descended on the tasty seed heads. I heard them chatter, I heard their songs. They were everywhere in the garden. I looked out my window andContinue Reading
