HPS/MAG 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. 




Please note that scheduling for Pop-Ups is ongoing.  Check this page often for additions. This is our 2022 planning time. For your convenience, we have grouped them by "Event Type". To see them chronologically, go to our events calendar.

NEW! Meet and Greet HPS/MAG Market Vendors. The fact that so many of you attended our August 2021 Fall Gardeners’ Market in the pouring rain is a testament to the quality of the vendors that brought a wonderful selection of plants to us. This year you will have the opportunity to visit some of these vendors on their home turf. Come out and meet the proprietors, tour their sites, and learn more about their plants and services.

Members Only. Free events but registration will be required so the vendors know how many members are planning to attend.
