The Metro-Denver Chapter welcomes everyone, members and non-members, to attend its free programs and field trips.  

MEETINGS: All are held at Denver Botanic Gardens, 1007 York Street, Denver. 6:30-8:30pm in the Plant Society Building, generally the 2nd Tuesday of each month, however day and date might change due to DBG scheduling. Meetings are free, and guests are welcome. Restrooms available.

DIRECTIONS: Park in the multi level free garage and cross the street.  During winter months (November - April) the gardens close at 5pm. Enter the gardens through the small iron gate north (to your right) of the entrance building; During warm months (May-Oct) gardens are open until twilight.  Go through entrance building, tell them you're attending a meeting.  Once in the gardens, walk straight west past the main conservatory and attached glass greenhouses. At the end of the greenhouses, turn north (right) and go through a large iron gate to the Plant Soc Bldg on your left.

WINTER SUGGESTIONS: While concrete sidewalk leading to the Plant Soc Bldg will be cleared of snow and ice by DBG, it is somewhat dim, so bring a flashlight and travel in groups (carpools are good!) Also wear warm clothing and appropriate boots/shoes since walk is rather long (about one city block).

We welcome everyone, from professional botanists and horticulturists to amateurs. If you're new to Colorado or just learning about our wonderful flora, don't be intimidated by sometimes complex terminology. CoNPS offers opportunities to learn about botany and plant identification. Our goal is to appeal to everyone through various learning opportunities at meetings as well as through classroom workshops and seasonal field trips geared to various levels of expertise.

Although Colorado has approximately 3000 different species of native and alien plants belonging to over 150 families - before you start feeling overwhelmed, concentrate on learning the major families since 75% of taxa (plant species) fall into major families. Everyone knows the sunflower family (Asteraceae) for instance, so build on what you know and HAVE FUN!
