Required Reading: Christin Geall’s ‘Flora Culture: How Flowers Shape Our World’

April 16, 2026

In her new book, floral designer and writer Christin Geall takes us on a global tour, discussing the culture of flowers with originality and wit. Well-paced and fabulously illustrated, Flora Culture: How Flowers Shaped Our World is a high-energy romp, backed by proper research and Geall’s personal experience. Treat it like an actual coffee table book, not left to languish in a pile but in full view, and dip into it. Picking a heading at random, be it Aroids, Chromophobia, or Endonyms, give yourself a leisurely few minutes to read, look, and think. We’ve been doing just that; here is a flick through:

Chapters are arranged alphabetically; terms used in the headings are not always known beyond the world of floristry and ecology. “Cold Chain: Plants on the Move” explains the lack of logic in sending plants around the world. The bizarre facts around the cold chain (the means of refrigeration used for storing and transporting perishables) are allowed to speak for themselves. For instance, the UK imports 90 percent of its cut flowers, this is despite considering itself a nation of gardeners—my aside.

The chapter on bulbs is a feast, describing familiar and not so familiar geophytes (terrestrial plants with underground storage systems.) Most rely on xeric conditions but many of the South African species (such as Crinum, shown above) are adapted to water. In a changing climate they will find the conditions they need. “If soil erodes around a geophyte or a rock is in the way, the plant is capable of moving. What? Yes!” writes Geall. “By alternately swelling and shrinking its roots, a geophyte can miraculously pull itself through soil.”

Emergents are plants that flower above water but the term can also refer to plants that rise above surrounding greenery. It particularly fits the lotus flower, which does both (“water lily leaves float on the water; lotus leaves hover above the surface.”). Other plants discussed in this chapter include miraculous papyrus, once “the cornerstone of civilization” but reduced now to about 30 cultivated acres in Egypt.

Geall looks at the “favored climes” of places like southern Europe, Morocco, and Japan, all considered subtropical and therefore the ideal climactic region for growing plants. Balboa Park in San Diego is in a subtropical zone and displays a rich variety of plants that were introduced to Southern California in the 19th century. The “Queen of Balboa Park” Kate Sessions was instrumental in this and like her plant collecting colleagues around the western hemisphere, she was able to import flowers that she fancied, with impunity. One legacy of this child-in-a-sweetshop situation today is the idea that anything that’s not native is more interesting. “Only about 27 percent of ornamental plants sold in the United States have North American roots,” writes Geall.

Geall advocates zero tolerance for plants considered invasive, having amended earlier views that using them as cut flowers could help keep them in check. The above picture shows the only way. Although this shows an example in Wales, the National Trust of Scotland has set up Project Wipeout, since half of Scotland’s rain forests are being smothered by Rhodondendron ponticum, introduced in the 18th century.

Christin Geall uses this quote from Alan Bennett to lead the reader into the chapter on “Floristry,” her specialty: “If you think squash is a competitive activity, try flower arrangement.”

Last peak, Endonyms. I’ve at last found an ally who has reservations about Carl Linnaeus’ system of naming and classification. Geall tells us that Linnaeus insisted on only Latin and Greek in naming plants, since non-classical languages were “barbarous.” (To me, who enjoyed Latin at school, botanical Latin might as well be pig Latin, it’s so convoluted). A lot of flora culture has sprung from the privilege of northern Europeans; this book is a spirited riposte.

Flora Culture: How Flowers Shape Our World, by Christin Geall, was published last week by Rizzoli.
