Yes, she spends a great deal of time chatting with growers, but this book has the BEST info on conditioning that you will find in a mass-market offering. Just as top chefs will alter recipes so that no one can duplicate their materpieces exactly, most flower growers are very tight-lipped about their secrets and will write pages and pages without giving specifics. Lee manages to extract wonderful information from her subjects.
Horticulture and marketing specifics are available in hundreds of other places: only here will you find a reliable guide to the best cut flowers and real, plant-specific conditioning practices. I used her advice for Cleome and won a blue ribbon at the county fair (the flowers lasted 2 weeks in the vase!). I use this book as my ultimate guide to plant selection and conditioning, and she has never steered me wrong.
