Thanks for bearing with me over the summer break, but On The Ledge is now back! In this week's show I talk to Australian university professor Dan Torre about his new book Cactus, published by Reaktion Books. It's not a how-to but a guide to the social, cultural and historical significance of cacti across the planet, from our love-hate relationship with this plant to its promise as a nutritious food source. And question of the week is back too. We’ll be finding out what fool proof plants are best for a newbie houseplant grower.

Below is a list of links related to our discussion that should help if you want to find out more:

  • The Green Horror comic story we discuss can be seen in all its glory on the Digital Comic Museum website. See below for a taster!
  • Read more about the history of the prickly pear as an invasive weed in Queensland on the Queensland Historical Atlas site.
  • Yes, there was an episode of the British sci-fi series Doctor Who featuring a cactus-like alien
  • The Pereskia cactus with its highly nutritious leaves (which taste like spinach...) is one I am definitely going to be investigating further.
  • Ask someone to draw a cactus and they'll probably do an outline of a Saguaro.
  • The dye cochineal is made from a scale insect that feeds on the opuntia cactus.  
  • Here's a bit more information on the dragon fruit which of course comes from a cactus (Hylocereus species).
  • You don't want to mess with the jumping cholla (Cylindropuntia fulgida) cactus.
