Upcoming Events

17th MACPS Meeting

1-5 pm on Saturday, November 12, 2022


MACPS is delighted to announce our 17th meeting, which will be at The Garden Plot (8453 Richmond Hwy, Alexandria, VA 22309). The schedule is packed with exciting events, including an open house, carnivorous plant swap, workshop on Venus flytrap care, talk on Nepenthes and their care, plant auction, and for the first time ever, a carnivorous plant show with judging! Here is an abbreviated schedule: 

  • 1-3 pm: Plant swap and raffle (raffle prize is a mature Nepenthes "Poi Dog")

  • 1-2:30 pm (concurrent with plant swap): Workshop on Venus flytrap potting and basic care

  • 2:30-3 pm: Plant show judging

  • 3-3:30 pm: The Plant Talk on Nepenthes care

  • 3:30-5 pm: Auction

The plant swap is for hobbyists to connect with one another and trade all types of plants, not just carnivorous plants. Please only bring plants in good health and without pests. Each plant, cutting, or propagation entered in the swap will earn the attendee one raffle ticket for a mature Nepenthes "Poi Dog," with a maximum of 5 tickets per individual (but feel free to bring as many plants as you like). Paid MACPS members will earn two raffle entries per plant, with a maximum of 10 tickets per individual. 

Every attendee will be able to participate in the Venus flytrap workshop and bring home their very own plant. Plants were generously donated by Carnivorous Plant Nursery and supplies by The Garden Plot. We will show you how to transfer a young flytrap from its plug pot into your own pot and answer questions about Venus flytrap care. 

We invite you to enter up to five plants (carnivorous only) in our show for judging! Please register your plants for the show by 6 pm on November 11 with the form linked below. Plants cannot be registered at the event. Entries will be judged on the following criteria: 

  • Health: Does the plant appear healthy?

  • Condition: Is the plant in good condition? Does it have any torn leaves, dried patches, or holes?

  • Size: Is it appropriately sized, considering the age of the plant?

  • Form: Is the plant aesthetically pleasing? Is it a wild tangle of stems/leaves/pitchers, or is it shaped nicely?

The Best in Show will receive our first place prize, a Nepenthes (chaniana x veitchii)  with a 12" leaf span! This is an extremely hirsute cross, with fuzz covering the plant from head to toe. Even the pitchers are velvety to the touch! Ribbons will be awarded to Honorable Mentions in multiple categories. 

The Plant Talk will be led by Rick Roberts, owner of The Garden Plot, who will discuss Nepenthes care starting from the basics. He will also provide advanced tips and tricks on how to make your pitcher plants flourish, including tips on proper fertilization, taking cuttings, and more!

As always, we welcome plants for the auction at the end of the meeting. 50% of the auction proceeds will go to MACPS (but you are also welcome to donate plants to MACPS). We will be providing some snacks and beverages.

We hope you can join us for what will likely be our last meeting of the year!

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.
