Legends of the Leaf

Unearthing the secrets to help your houseplants thrive

Jane Perrone · Originally Unbound; now self-published, 2023

Twenty-five house plants, taken seriously — where each one grows in the wild, how it reached our windowsills, and what that tells you about growing it.

Before you buy Unstable availability

Perrone's publisher, Unbound, went into administration in March 2025. Rights reverted to her and she has self-published a new paperback. That means the ISBN, price and stock for this title are all moving — check what you're actually buying before you order.

What's actually in it

  • 25 chapters, one plant each, ordered by botanical name.
  • Each pairs a narrative essay — origin, wild habitat, discovery, the colonial plant-hunting history, cultural and scientific significance — with a full practical care guide.
  • Care covers light, temperature, watering, humidity, substrate, feeding, pests and diseases, propagation, display and "danger signs" — the symptoms that mean trouble.
  • The 25: marimo, aloe vera, aspidistra, polka dot begonia, string of hearts, spider plant, jade plant, string of pearls, dieffenbachia, Venus flytrap, pothos, fiddle-leaf fig, English ivy, kentia palm, hoya, lithops, monstera, Boston fern, bunny ears cactus, oxalis, Chinese money plant, snake plant, strawberry begonia, peace lily and ZZ plant.
  • An extensive bibliography — and Perrone publishes her per-chapter sources publicly, which almost nobody does.

What it actually says

Specifics from inside the book — so you can judge whether it's telling you anything you don't already know.

  • She publishes her sources, free, chapter by chapter. A full bibliography for all 25 plants sits openly on her website — peer-reviewed papers with DOIs, JSTOR references, dissertations, and nineteenth-century material from The Gardeners' Chronicle. We are not aware of another popular house plant book that does this.
  • The dieffenbachia chapter is the book at full stretch. The sap swells the mouth and prevents speech — the origin of "dumb cane" — and she documents that enslaved people on plantations were forced to eat the canes as punishment, and that Nazi researchers experimented with extracts as a sterilisation agent. The chapter carries an explicit content warning. She also covers the plant's wild ecology: rainwater collects in the leaf joints, where mimic poison frogs deposit tadpoles.
  • A conservation figure that reframes a supermarket plant: less than 2% of the wild Venus flytrap population remains in its native Carolina coastal plain. Her care advice contradicts most retail guidance — full sun or grow lights, a cool winter rest, soft water only, and don't feed them.
  • Dated social history, specifically sourced. Kentia palms stood at either end of Queen Victoria's coffin at her 1901 funeral, were aboard the Titanic, and furnished the Ritz. The same entry gives the diagnostics: blackened leaves mean overwatering, straw-like leaves mean sunburn.
  • A cheap, specific technique: if a spider plant looks dull and washed out, submerge the whole pot in a bucket of water for half an hour.

Buy it if

You already keep house plants alive and want to understand them rather than just maintain them. The best-written book on this shelf.

Don't buy it if

Someone with one dying pothos who needs an answer today. If your plant isn't among the 25, it isn't in here.

Where it falls short

Twenty-five species is the whole point and the whole limitation — there's no directory function at all. No styling, no propagation tutorials beyond the per-species notes. Toxicity is handled seriously where it comes up (the dieffenbachia chapter is direct about the sap causing severe mouth and throat swelling, and says plainly it's unsuitable around pets and small children) but it's narrative rather than a standard field, and 25 species can't serve as a safety reference.

Who wrote it

Perrone was gardening editor of the Guardian for the better part of a decade and hosts On The Ledge, the house plant podcast she started in 2017. She writes for the FT, Gardens Illustrated and the RHS's The Garden, and is a network member of the RHS Tender Ornamental Expert Group. She gardens in Bedfordshire, at about 52°N — the same light as her readers. She has no formal horticultural training, and reached the subject through journalism. That is precisely her value: she is a rigorous researcher rather than a credentialled horticulturist, and she shows her working in a way nobody else on this shelf does.
