If you love plants and want to learn more about how to grow them, where to get them, and how to use them in your garden, we cordially invite you to join us for HPS/MAG Pop-Up Events, Programs, and Special Interest Group (SIG) Activities.

We are anticipating 2021 to be a vaccination year that will allow us to bring back in-person HPS/MAG activities. We plan to offer a year filled with wonderful, informative, fun and varied Lectures, Wholesale Shopping Opportunities, Pop-Up events and SIG activities. And we can't wait to engage our members with lots of terrific horticultural experiences. We will continue to offer virtual events until it is safe for us to meet. 
Some activities include non-members also but join today to ensure you can immerse yourself in all that HPS/MAG has to offer.


Pop-Up Events 

Pop-ups are member-sponsored events that don’t fall under the categories of our established Special Interest Groups. They can include members and nonmembers as participants and take place throughout the year. They cover a wide variety of interests - for example: workshops, garden tours including historical sites, and day trips.
