Episode 3 – Araucaria heterophylla, aka Norfolk Island pine

Episode three of Every Plant Deserves a Podcast centers around Araucaria heterophylla, aka the Norfolk Island pine. We recorded this episode in late November, which is about the time that garden centers, box stores, and grocery stores fill up with this lovely Australian-native conifer. It’s sold as a “living Christmas tree” – a plant you can use to fill that role during the holidays, and then go on to keep (ostensibly) as a houseplant for years to come. But the fact is that Norfolk Island pine is pretty farm from ideal as a houseplant, as you’ll discover in the episode when we talk about the very unique climate of Norfolk Island and how different that is from the conditions in the average North American home, especially during winter.

Learn more about Norfolk Island, Mutiny on the Bounty, living fossils, the issue of glitter on your Araucaria heterophylla, and how you can hopefully/maybe find success growing this tree indoors.

Right off the bat: here’s where Norfolk Island is.

The fascinating story of Wollemia nobilis, a relative of Araucaria heterophylla, known only from the fossil record until a grove was discovered in New South Wales, Australia, in 1994.

Read about the Cretaceous-Paleogene Extinction, which wiped out the abundant Araucaria sp. that once grew across North America (oh yeah – the dinosaurs got wiped out then, too). 

Araucaria wood is not generally suitable for use as structural timber, but here’s some info on its use in decorative applications.

The history of Norfolk Island is quite a ride…

This quick read on the climate of Norfolk Island will help you figure out the best place for your Araucaria heterophylla indoors – or at least help you understand why yours is struggling.

A useful link for those of you lucky enough to be able to grow Araucaria heterophylla outdoors all year-round.

In this episode, we also discuss the monkey puzzle tree, Araucaria araucana, a close relative of Araucaria heterophylla. It has a coarser habit and much larger “needles”; It’s also much hardier and can be grown in areas as cold as USDA zone 7.

This species, native to Chile, was the first such described, which explains why the family (Araucaraceae) and all other members of the genus bear this name, despite being native to the South Pacific. Learn more and see more pics in this great article.

Episode 2 – Vaccinium macrocarpon, aka cranberry

Vaccinium macrocarpon, better known to most people as the cranberry, is the focus of today’s episode. This is partly due to seasonality – we’re coming up on Thanksgiving here in the US, and for those who aren’t familiar, cranberries typically play some role in the traditional holiday meal. It’s also due to the fact that everyone knows of cranberries, but few have actual laid eyes on this plant in the wild — though we’re guessing that they grow within a 20 mile range of a good chunk of those listening in the US and Canada.

Episode 1: Hydrangea paniculata, aka panicle hydrangea

Hydrangea paniculata features in the inaugural episode of Every Plant Deserves A Podcast for several reasons: one, it’s a plant that can be grown over nearly all of North America, from the chilliest northern locales to those in the steamy South, so it should be visibly familiar to people, whether or not they know it by name. Two, because this plant, now so ubiquitous in North American gardens and landscapes, has a long and unexpected story behind how it got here, and finally, three, because a big part of the Proven Winners ColorChoice Shrubs brand was build around one game-changing panicle hydrangea, ‘Limelight’.
