Belfast Botanic Gardens Tree Archive
This is one of a series of short articles about trees in the Belfast Botanic Gardens compiled by the Friends group. The tree tag number relates to the small aluminium discs, usually fixed on the tree trunk, 2 to 3m above ground level.
Araucaria heterophylla (Salisb.) Franco
Norfolk Island pine
This month we are staying in the relative warmth of the palm house
to look at a member of the monkey puzzle family. It is, of cause, not a pine, belonging to the family Araucariaceae. The familiar monkey puzzle,
Araucaria araucana, is hardy and has thrived in Northern Ireland since
introduced shortly after 1844. It is now an icon of the Victorian age that is
still planted, sometimes in totally unsuitable front gardens where it can grow to over
30m high! The Norfolk Island pine is much less well known, as it is frost tender,
surviving out of doors only on Tresco in the Scilly Isles. It is one of the
most distinctive and elegant trees when fully grown with an amazing symmetry. It
is native to a single island north of New Zealand but is cultivated in many warm
countries round the world.The two trees in the Botanic Gardens Palm House are only a few years
old, but are already quite striking.
Since writing this in 2014, a Norfolk Island pine has been planted out of doors in Mount Stewart Garden where it seems to be doing well. Yet another sign of climate change.
