14th MACPS Meeting

12-4 pm on Saturday, August 14, 2021


After almost 2 years of virtual meetings, we are delighted to announce that the 14th meeting will be in-person at the Cylburn Arboretum in Baltimore, MD on Saturday, August 14, from 1-4 pm! The schedule will feature a panel Q&A on carnivorous plant cultivation, a presentation by Bill Schwartz on his expeditions to see Nepenthes in the wild, several other talks, and a carnivorous plant auction. RSVP for the meeting here

In keeping with our pre-COVID tradition, we will be providing lunch, courtesy of Carnivorous Plant Nursery! These will be individual boxed lunches. Please let us know your lunch selection on the RSVP form. If you will be coming with more than one person, please submit a new form for each person so we can organize lunch purchases.

We recognize that the COVID-19 situation is still tenuous, particularly with the delta variant becoming predominant. As such, masks are mandatory at this meeting. We will not only be enforcing mask wearing, but correct mask wearing (covering both your nose and mouth). Additionally, the conservatory will require you to sign a waiver assuming personal risk of COVID, and will also be performing temperature checks. If you are experiencing symptoms (fever, runny nose, cough, etc.) please do not attend this meeting. Please social distance during lunch.


The end of the meeting will feature a carnivorous plant auction. 50% of the auction proceeds will go to MACPS (but we would, of course, be delighted if you wanted to donate a plant to MACPS). To streamline the auction, we strongly encourage you to preregister your plants using this spreadsheet. You are also welcome to register plants at the meeting. Please bring cash for the auction (but we will also accept PayPal). 

The entrance to the venue is through Greenspring Avenue, and the venue is actually part of Cylburn Arboretum. We will be meeting in the greenhouse classroom. Please park in one of the three parking lots labeled "Regular Parking" on the map, near the Vollmer Center. Lunch will be available in the patio space near the greenhouse classroom.

About Us


Founded in January 2017, MACPS is a not-for-profit organization dedicated to promoting scientific knowledge, education, and general awareness of carnivorous plants and their cultivation. We hold four meetings a year throughout PA, MD, VA, WV, DE, NJ, NY, and Washington, D.C., and also go on field trips and exchange cultivation advice that is uniquely suited for this region. 

Our meetings are open to everyone! They feature lunch, a moderated Q&A on carnivorous plant cultivation, talks, workshops, and a plant auction. You are always encouraged to bring plants to display and auction.
