PLEASE NOTE: The dates and times shown to the right reflect only the start and end days and times! See below for all actual class dates and times.

Three of the most difficult and largest plant families are the Asteraceae (asters), Brassicaceae (mustards), and Poaceae (grasses). They may be challenging, but a working knowledge of just these three will allow you to identify one of every eight plants in the world! At our indoor session we’ll cover the recognition characters, specific terminology, and morphological characteristics you will encounter when keying out members of these families. In the field we’ll dissect flowers, examine their specific parts, and key out plants using Flora of Colorado. Don’t be afraid of these families any longer! We’ll use hand lenses to view parts close-up. Bring your camera and questions, and be prepared to have fun while learning about Asters, Brasses, and Grasses!

Are there ID or minimum age requirements to enter the event?

Our classes are geared toward adult learners. The minimum age for attendance is 18.

What are my transportation/parking options for getting to and from the event?

Class locations are provided to registrants about two weeks before the class starts in a "Welcome" email from the Instructor. Come directly to the location of the first class and Jannifer will meet you there. On the field day, we will meet at a location specified at the Friday evening class.

If you wish to carpool on the field trip, you can make your own arrangements. We will provide a list of participants who allow us to share their names and emails for this purpose. While we suggest that all occupants share the fair cost of gas/operating costs, BCNA does not organize or participate in any carpool arrangements. If you carpool, please discuss and agree on your travel plans in advance.

What can I bring to the event?

You will want paper and pen/pencil on both days. The instructor will let you know if there is anything specific that you should bring to the field session. Otherwise be prepared for time outdoors, away from the car. You might bring a daypack with water and food for snacks. Wear hiking clothes and footwear adequate for conditions. Bring sun protection (sun lotion, sun glasses, hat, long sleeves), bug dope, and any field guides, binoculars, trekking poles, or other personal items and extra clothing you might want.

How can I contact the organizer with any questions?

Please email [email protected] We do not check this account every day, but will try to get back to you within four business days.

What's the refund policy?

We open registration for each class just six weeks before it begins so that you will have a good idea of your availability. Our apologies, but refunds are not available. Most of the proceeds from classes go to our instructors. The remainder helps support our education program, research grants, publications, seminars, and conservation efforts. If you must cancel, we hope you'll consider your payment as a donation to the Boulder County Nature Association. Of course, if we must cancel a class, your payment will be fully refunded.

Is my registration fee or ticket transferrable?

Yes. Just log on to your account, go to "Tickets," select your order, and then choose "Edit." Change the name and email address to the new attendee's information. Be sure to check the box and we will send them a confirmation email with all the ticket/registration information they'll need. Once you're done, select "Save" to save your changes.

Demand for our classes is high and participation is limited. Classes usually fill up early, and we maintain a waiting list. If you cannot attend or find a substitute, please let us know as soon as possible so that we may offer your spot to someone else.

Can I update my registration information?


Do I have to bring my printed ticket to the event?

No, your name will be on our registration list. You may print your Confirmation Email if you want a record
