Ep10: Houseplant Confidential with Jane Perrone


On this episode, we’re taking an intimate look at the the most domesticated plants of all: houseplants. These ecological oddities are truly dependent on their human owners to provide them with adequate light, water, and care. For that reason, we can’t help but project our feelings upon them.

My guest, Jane Perrone, is a London-based journalist and the host-producer of the indoor gardening podcast On The Ledge. Her show is partly about plant collecting, propagation, and care, and partly about the people behind the plants: the botanists, the growers, and the stars of “houseplant Instagram,” who all have a role in determining which species are hot, and which ones are not.

We’ll discuss Jane’s background, some myths and misconceptions of container gardening, and the human tendency to anthropomorphize our houseplants. 

Do you name your plants? Play music for them? Do you love your plants to death? As Jane points out, overwatering is the leading cause of mortality for houseplants. Many seasoned gardeners still insist on adding “crocks” (broken pottery or rocks) to the bottom of pots, although science shows that this practice doesn’t help drainage, and can be detrimental to plant health. Then there’s the rather avant-garde notion of fertilizing your plants with bodily fluids. (Though there is a good argument to be made for the “menstrual option,” Jane has read up on the subject and says “it’s probably not a good idea.”) 


At the top of the show, I’ll dive into the revealing history of the Aspidistra elatior, a houseplant once so iconic it was the subject of a popular song, the codename for an Allied “black propaganda” operation in WWII, and the central metaphor in a George Orwell novel. Today, the Aspidistra is barely considered a houseplant at all. Can this casualty of fashion ever come back in style?
