Featured Book

There are many Colorado wildflower/natural history books, but none equals Colorado non-fiction book award winner, Wild at Heart by Janis Huggins. If I had to choose just one Colorado high country wildflower/natural history book for most people, this would be the one. It contains superb photographs and accurate descriptions in a beautiful layout. To purchase, email Janis.


Immediately below you will find links to comments & updates on three Colorado floras.

Floras are complex and very time consuming to write. They demand not only expertise in the plants of an area but also expertise in technical writing, logic, and scientific precision. Three recent floras of Colorado strive for these goals and achieve them to various degrees, but all three have room for improvement, especially in the construction of clear and accurate keys.
