I didn't really agree with quite a few of the plants featured in this book as being "resilient". You know some of them are already fussy when the author herself says they need high humidity, don't like this/that, can't tolerate blah blah and so on. I also speak from personal experience, because many of the plants she lists as "unkillable" are actually not. A few I would say can even be classified as "difficult" to keep alive/healthy. But I liked the book's conciseness and simplicity - the author doesn't tell you more than you need to know, and every plant comes with a handy list of features.
(As an aside, I noticed that none of the cacti featured had "air-purifying" qualities. Does this mean they don't clean your air?! The green leafies all did, except for some of the palms!)
