Besides the Timber Press book Gardening with Hardy Heathers by Wulff and Small, my favorite heather resources have been two slender booklets published by the International Heather Society and given to me by our local Heather guru Maria Krenek. The books are about how to care for and grow heathers successfully, and which heathers they recommend most.
Until now, ordering those books required getting in touch with the Brits and figuring out exchange rates and all of that… Kind of complicated for such tiny booklets!
Imagine my pleasure then to notice that they are now offering these booklets as free PDF downloads! You can read them online or save them to your computer to read or print out as you like.
