Frequently Asked Questions

The direct route to the Colorado Plant Database is its address at
Another way to get here is from the Jefferson County Extension Home Page at where you can click on the Colorado Plant Database link.

Where does the data come from and how often is it updated?
The plants presented here are derived from a database of more than 1,000 Colorado plants that are studied in Native Plant Master® field courses held around the state. The award-winning Native Plant Master Program is sponsored by Colorado State University Extension and other agency cooperators. The database does not contain all plants that can be found in Colorado, but plants are added each year as more courses are offered at different sites.
Information on the plants listed is from a variety of research-based resources that are listed in the references section of the database. Nomenclature is from Colorado Flora, 4th edition, by William A. Weber and Ronald C. Wittmann. Content updates are made as frequently as quarterly but at least annually. The database format is also periodically updated. The release date of the current version is listed at the bottom of each webpage.
It should be noted that any information about the edibility of plants is given strictly for historical purposes. We do not vouch for the safety of eating any plants mentioned in this database.
In addition to safety considerations, we do not recommend collection of any native plants or plant parts because this can negatively impact plant populations. A number of rare native plants have become classified as threatened or endangered because of human collection.

How do I view information about a specific plant?
Click on the ‘Search for Plants’ tab or link and choose one of the search options, then click on the plant of interest to see the Plant Detail screen.

What is "Blooming Season" all about?
This link lists all plants that have been observed to bloom during a specific season. For example, when the spring button is clicked, a list is produced of all plants that bloom some time between January and May. Plants will sort in order of how early in the season they bloom. If a plant blooms in spring and again in the fall it will appear in both the spring and the fall lists.

Why might the quality of the photographs be poor?
The capabilities of your browser, computer, and/or monitor might not support the full resolution or range of colors in the photographs. To determine whether your system might need to be modified, please view this test image which should appear to you as a smooth transition of colors.
