Do you have questions about native plants? Would you like to share information and enthusiasm about native plants? 

Join the Colorado and/or New Mexico Native Plants on-line botanical discussion groups for amateurs and professionals. Participate as much or as little as you want to. Send in photographs of native plants for identification and discuss key issues about conserving native plants, techniques for growing native plants in your garden, plant photography, etc.

Be aware that the first two Facebook pages linked immediately below, often have irrelevant wandering comments. The New Mexico group is very good with well thought out questions and very courteous and helpful responses.

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. Weber's flora has many helpful comments found nowhere else, but the keys are needlessly complex. Ackerfield's flora improves on Weber's but contains many problems. Heil and O'Kane's flora is the best for the Four Corners region (and beyond) and has the great advantage of being put together by many experts, not just one author (as in Weber and Ackerfield's floras).

A Utah Flora by Welsh is often the flora I turn to for the best keys and most interesting and accurate comments.

The Flora Neomexicana III by Allred is a very well researched flora that has very good keys but data on plant distributions has many lapses.
