Initially this guide displays common flowers of all colors that are blooming right now in our area. Use the selectors to view rare species, to view flowers blooming any time, to restrict the output to a certain color, or to search by name.
The Jemez Mountain Herbarium located at PEEC has a specimen collection of over 1,000 plant species that are found in the Jemez Mountain region. This guide was developed as a subset of this collection to help in the identification of the most prevalent flowering plants in Los Alamos County. Most of the plants shown here are native to the area, though a few were introduced to the region.
Monocot and both simple and composite flowering dicots are covered in this guide. This information is included in each description and potentially makes it easier to identify the different plants.
- monocot – seed has 1 embryonic leaf; flower parts com in multiples of 3; leaves have parallel veins
- dicot – seed has 1 embryonic leaves; flower parts com in multiples of 4 or 5; leaves have scattered veins
- simple flower – single, symmetric flowers; usually 3 to 6 petals that emerge from the flower center
- composite flower – multiple, tiny flowers arranged on a single base, typically rays around a disc; each tiny flower has its own seed
Most of the plants represented here are classified as forb/herb which are plants without significant woody growth. However, some flowering shrubs and trees have been included. Many of the later can also be found in the PEEC Tree Guide. This guide does not include any noxious weeds from the area. These are covered in the PEEC Invasive Plant Guide.
