I hate seeing “ultimate” in any book title. There are many good books on almost every gardening topic. How can one deserve this designation above all the rest?
I had the privilege this winter of sitting on the committee deciding the American Horticultural Society’s 2025 Book Awards. As the review copies of nominated books arrived, my bias caused me to immediately downgrade “The Ultimate Guide to Houseplant Propagation” by Lindsay Sisti.
Fortunately, the rigor of the committee required me to spend much more time with this new book – and I discovered it’s a treasure! I recommend it for anyone who has a pandemic induced houseplant collection, and even those with a long-standing indoor forest of green.
If your propagation skills are like mine, they aren’t much beyond sticking a leafy stem, broken by accident, into a glass of water and hoping. While this can work, the author provides many more ways to increase your plants with greater success. I also appreciated her insights into different soil mixes, and the tools that can make your work easier. For example, I hadn’t realized the value of a magnifying lens as a gardening tool.
Most of the examples use asexual propagation, but there is a chapter on creating your own hybrids from the seeds of flowering plants, using anthuriums (Anthurium sp.) as the model. Another chapter works through the details of increasing succulents; a process distinct from most typical houseplants.
This is not a selection guide, but it does feature several of the more popular choices as examples. It also has hints for dealing with a plant that is not thriving, including freeing a pot bound underperformer, or even saving a diseased favorite.
While I haven’t changed my opinion about the use of the word ultimate, I think that author Sisti has come close to that ideal. The AHS committee agrees, giving her book one of the 2025 Book Awards. Throughout, she uses a sometimes quirky sense of humor to engage the reader, but with an overall clear intent: “Do whatever brings you—and helps you spread—joy . . . and plants!”
