Silhouette and Cross

The silhouette of the Norfolk Island Pine is highly distinctive. The Christian cross at the top of the tree makes it an apt choice as a Christmas Tree. It is also an appropriate choice for the final Advent Sunday blog of 2018.

Classification and Origin

The Norfolk Island Pine is not a Pine tree at all. It is a member of the Kauri-tree family or Araucariaceae. This plant family is mainly found in the Southern Hemisphere and is more familiar for its Monkey Puzzles.

The Norfolk Island Pine dates back 200 million years ago to the Jurassic Period, when all the continents were a single land mass. The tree later developed in splendid isolation.

IUCN Red List Status

The tree is endemic to Norfolk Island and even features prominently on its flag. Today, it is classified with a Vulnerable Conservation Status on the IUCN Red List of Threatened Species. Eighteen of the island’s other endemic species are considered Rare or Threatened.

Location and History

Norfolk Island is a small island between Australia, New Zealand and New Caledonia. It has had an interesting and colourful history. It was uninhabited when spotted by Captain James Cook. It was chosen as a penal colony for its remoteness.

HMS Bounty Descendants

The island became home to the Pitcairn descendants of Fletcher Christian and the HMS Bounty mutineers. Gravestones in the island’s cemetery testify to this history.

Climate

Norfolk Island has a warm climate. The temperature rarely falls below 10ºC or rises above 28ºC. The Norfolk Island Pine tolerates salt spray. There is only one place in the United Kingdom where the climate is suitable for this special tree: the Isles of Scilly.

Tresco’s Norfolk Island Pines

The following photographs of Norfolk Island Pines were taken during my visit to the Scilly Isles and Tresco Abbey Garden in August 2017.

Tresco Abbey Garden

Tresco Abbey Garden was created by Augustus Smith in the 19th century. It incorporates the remains of a Benedictine Abbey of 964 AD. Thousands of exotic plants flourish outdoors there. Those same plants would not survive 30 miles away on the Cornish coast.

August Smith created shelter belts to protect the gardens from the salty Atlantic gales. He corresponded with Sir William Hooker at Kew Gardens about his plant collection. Tresco Abbey Garden can grow plants outdoors that Kew has to keep inside in its large glasshouses.

A House Plant?

When you have seen large Norfolk Island Pines, it seems strange that they are considered house plants in the U.S.A. They are commonly sold as a small Christmas Trees there. This earns the Norfolk Island Pine the common name of the Living Christmas Tree.
