Tim,
No Kindle version is planned but Schiffer keeps the price very reasonable on their books so it is not a burden. I know I'm old-fashioned but to me there is no substitute for PAPER. The book on beardless irises that I did for them is ~$24 on Amazon. Much cheaper than the Timber books and Schiffer's art people are much better so the layout is more pleasing.
I actually retired early with the intent of doing the plant breeding and book writing as a second career. As my mom said of me,"Kevin doesn't have hobbies, he has other jobs." Unfortunately all too true.
Looks like Canby got more snow than we did. I'm NOT complaining though.
Like you I'm looking forward to April although I do have some hellebore seedlings I want to see too. They should be out in February as many are showing buds coming.
Kevin
