Marilee Benore, PhD, Professor Emerita of Biochemistry & Biology, U of M-Dearborn, on Mountainmint

Perennial Plant of the Year® 2025 – Perennial Plant Association
Clustered Mountainmint (Pycnanthemum muticum)

We have a plot of this on campus (but overly weedy) and my lab in coordination with Professor Simona Marincean  have been conducting research on the essential oils. There has been little work on its use in products, but the smell is heavenly. I do not recommend eating or drinking it due to a small pulegone content, but it is a lovely lovely plant, and the stems stay upright all winter.  Picking a leaf or two and rubbing it between your fingers releases a peppermint/spearmint aroma. We distilled the oils and tested the chemistry and its ability to inhibit bacterial growth.

MGAWC's Margot McCormack Celebrates 45 Years as Master Gardener

Link below to a nice article about Margot McCormack’s 45 years as an MSU Extension Master Gardener volunteer, 1980-2025. Congratulations and thank you for 45 years of service to the community and volunteer work in gardens and teaching others. Margot is extremely generous with her expertise, time and plants from her garden.

PLEASE NOTE CORRECTION FOR ACCURACY:

The caption under the photo should refer to the Master Gardener Association of Wayne County (MGAWC) to match the cake in the photo. The picture was likely taken during a special shopping day for MGAWC members and guests at Christensen’s Plant Center. Besides Margot McCormack, other people pictured include Kathy Frank, Tonja Nudi, Wayne Watson, Barbara Greenberg, Martha Forst-Watson and Beverly Evans.

The other cake on the right was likely to celebrate Elaine Weider’s birthday, MGAWC’s treasurer at the time.

LEARNING FROM THE PAST by Gail Morrell, Professional Gardener 

Handout for Gail’s February 2025 presentation to MGAWC members on Zoom:

Perennial Plant of the Year® 2025 – Perennial Plant Association

Clustered Mountainmint (Pycnanthemum muticum)

Not a true mint but described as robust!  USDA zones 4 to 8; 2-3’ tall & wide; blooms white-light pink July thru Sept with silver bracts; full to part sun; deer and rabbit resistant; pollinator plant and larval food of the Wavy-lined Emerald Moth (Synchlora aerate).

 Hosta of the Year – American Hosta Growers Association

            Skywriter – blue hosta with corrugated leaves and purple stems. 1.5’ tall and 4’ wide

 Moths – 160,000 moth species compared to 17,500 species of butterflies worldwide!

Silk Moths - Caterpillar stage lasts for 37 to 52 days feeding with a ravenous appetite. Adults do not feed; they have no proboscises and only live for a few days to mate and lay eggs!

 Polyphemus Moth (Antheraea polyphemus)

            Laval host plants ash, birch, grape, hickory, maple, oak, and pine

             Cecropia Moth (Hyalophora cecropia)

            Laval host apple, ash, beech, birch, elm, maple, oak, and willow

 Parasitic plants

Dodder (Cuscuta) 150 species worldwide.  They are holoparasitic meaning they have leafless yellow/orange stems and use haustoria (modified roots) to get all their water and nutrients from the host plant, they do not photosynthesize so do not produce chlorophyll.  It is a self-seeding annual but once sprouted can only survive 5-10 days without a host plant.

 American Mistletoe (Phoradendron leucarpum) 240 species in the Americas.  They are hemiparasitic, most have leaves or scales and do photosynthesize.  They get all their water and mineral nutrients from their host.  Host plants include maples, oaks, ash, walnuts, elm, poplars and more.  They are considered an evergreen shrub.  American Mistletoe is the primary larval food of the Great Purple Hairstreak (Atlides halesus)

 Houseplants

            Terrariums

            Plastic saucers for containers

 Feeding the birds

            Kensington Metropark

Bring your own seed and hand feed the birds!  Black-capped Chickadees, Tufted Titmouse, Downy Woodpeckers, and White-breasted Nuthatch

 Container plant

Tall Verbena (Verbena bonariensis) USDA zone 7-11 (an annual for us) Lilac flowers; airy see through habit; 3-6’ tall, 1-3’ wide; blooms all summer; attracts hummingbirds and butterflies.

Nature Journaling Resources from Karen Gourlay

Journaling about nature can be a fun and creative way to spark curiosity and improve your observational skills. Nature journaling can also be a benefit to your annual record-keeping by prompting you to observe your garden more closely, track seasonal changes and interactions, and make comparisons over the years.

Ideas to get started: (1) I notice …, (2) I wonder …, (3) It reminds me of …

Various approaches or languages; start with your comfort zone, then add

  • Words -- descriptions, stories, poems, questions, lists, location, landscape (forest, wetland, garden, etc.)

  • Pictures -- drawings, boxes, arrows, maps

  • Numbers -- counts, time, date, charts, graphs,

 When facing a blank page, start with meta-data, maybe a block on top with:

  • Date

  • Time

  • Weather

  • Temperature

  • Location

Then add some boxes or circles for a note, a sketch, a map, break the page into small sections for focusing on different aspects

On the first page of new journal, maybe:

  • Favorite quotation

  • Goal

  • Table of contents (or opt for an index at the back)

Focus your attention on something that catches your interest

Focus on the process, not the page

 Prepare a journaling bag—that you keep by the door or in the car—that might contain:

  • Current journal

  • Favorite writing utensils (pens, mechanical pencils, colored pencils, whatever)

  • Binoculars

  • Small jar or plastic bag to collect something

  • Tape measure or ruler

  • Handheld magnifier

  • Small watercolor kit with water brush containing water in the barrel

 Have fun — It’s just for you — Doesn’t have to be perfect or anything you ever share with anyone else
