Program Information


GROW Adult Education programs are for adults 18 and older. BRIT and the Fort Worth Botanic Garden endeavor to offer a quality educational experience to each program participant, with class sizes supporting this policy. Registered participants may not bring an unregistered participant of any age to class. Onsite registrations, when a class is not sold out, are encouraged.

GROW members may register for courses at the discounted member rate; guests of members do not qualify for the member rate. Program registration fees include complimentary entry into the Botanic Garden the day of the program. Entry to BRIT is always free. 

Many courses are held outdoors and may require moderate walking to and from one or more locations. As such we recommend that participants dress comfortably in clothes that are appropriate for both indoor and outdoor adventures. If you have questions about physical requirements, please send an email to 


To cancel your registration for a class, please email at least ten calendar days prior to the start of that class. You will receive an 85% refund. No refunds are granted less than ten calendar days before the class starts.

If you choose, you may gift your seat in the class to a friend or family member; just send us the name and email address of the person who is taking your spot so we can add them to the roster and send them the appropriate information.

Payment for your class reserves your seat and allows us to secure the instructor. If you are late for class, your seat will be reserved; we do not transfer your seat to walk-in participants. Partial refunds or transfers are not available for unattended classes.

In the event that we must cancel a class, you will be notified email and will have several options: we can transfer your ticket to another class right away (or classes, so long as the new value does not exceed the original value), issue a credit to be applied to another class or classes in the same calendar year, or provide a refund. This applies to classes that do not meet the minimum registrant requirement, which sometimes occurs.

By registering online, over the phone, or in person, you are agreeing to GROW's ten-day cancellation policy outlined above.

Join Richard Spellenberg and Naida Zucker, authors of the newly published The Sunflower Family: A Guide to the Family Asteraceae in the Contiguous United States (BRIT Press) for a lecture titled "Knowing the Sunflower Family in Texas." This presentation is based on the newly published book, which details all the approximately 430 genera of sunflowers and relatives in the contiguous United States. The Sunflower Family (Asteraceae) is the largest of plant families, with about 30,000 species. It is found in all habitats, is showy, many species are used for ornamentals and some for food. They provide large swatches of color on the landscape in the warm months and contribute to the misery of pollen allergies in many areas of the country. Though it is a family with many beautiful species, it is to most people baffling because of its compound head of flowers and complex terminology. The presentation covers the mysteries of the sunflower head, genera found only in Texas, a review of some of the widespread, common genera in Texas, and how one goes about identifying these interesting plants. 

A workshop with the authors will follow the lecture and will look at examples detailed in the book. Refreshments will be served, and copies of The Sunflower Family: A Guide to the Family Asteraceae in the Contiguous United States will be available for purchase at a discounted rate of 10% off for lecture attendees (this discount can only be applied in person the day of the lecture). The authors will be available to sign books, whether your copy has been brought from home or newly purchased at the lecture.
