This year I have the honor of introducing you to some of our newest additions to the Red Wagon Plants medicinal herb family. In addition to the many medicinal herb starts we grow every year, we have added some plants that are tried and true herbal allies, if not as common in the modern Vermont garden. 

Medicinal herbs tend to be very closely related if not identical to their “wild” counterparts, with very little breeding done by humans for horticultural production. In this way, the most adaptable and hardy plants tend to thrive, and those very compounds that aid the plant’s survival also serve to act medicinally in the human body. Horticultural plant breeding is often targeted towards things like bloom time and flower color, so medicinal constituents may decrease as the plant adjusts in favor of these showy adaptations. For those of us who appreciate a more natural looking perennial garden, the wild beauty of the unmodified plants is part of their charm, and an assurance that we are growing high-quality medicine as well. 

Another trick to medicinal plant growing is germination. Many of these more wild plants have adaptations to ensure seed viability which actually make them much more difficult to reliably germinate at home. Replicating the plant’s natural experience, such as letting the seeds go through a period of cold stratification (for northern climate plants) or nicking the seed coats to mimic the passage through an animal’s intestine, will help increase germination. They’ll never behave quite like a tomato or spinach seed, because these medicinal plants have not adapted to rely on human propagation. This means that buying established plant starts is a great way to ensure success this year, and you’ll be able to save seed to experiment with expanding your patch in years to come. 

You’ll notice that a couple of these plants have the species name “officinalis”, as do other herbs that we grow; that’s a clue to the fact that these plants were historically included in official pharmacopeias and monastic apothecaries well before Linnaeus’s time in the early 18th century. 

Without further ado, here are some of the newest additions to the Red Wagon medicinal herb family:

Marshmallow (Althea officinalis): A relative of hollyhock and hibiscus, this pale-pink flowering beauty lives up to its name, thriving in wet or dense soils. It will also do just fine in garden soils with enough moisture. Growing 3-5’ tall, plant marshmallow towards the back of your perennial beds, but still within easy enough reach to harvest the flowers and soft, velvety leaves for tea. All parts of this plant, including the 2+ year old roots, are valuable for their soothing mucilaginous qualities, which smooth out digestion and soften skin. A great herb for the kid’s garden!

Wood Betony (Stachys officinalis): This plant used to be a staple in old European herb gardens, and has been venerated for centuries as a panacea to “preserve the liver” and ease emotional malaise. Well-behaved clumps of deep green leaves form attractive mounds for the front of the garden, with stately 2’ spikes of purple flowers that will continue to sprout as you harvest through the season. Clip back stems, leaves and flowers and dry for a subtle, earthy tea that can clarify the mind and support healthy digestive function.

Skullcap (Scutellaria lateriflora): As our retail manager and fellow herb aficionado Lily said, “After 2020, everyone could use some skullcap!” A native wetland herb in the Mint family, skullcap will happily sort itself around plants like marshmallow and valerian, growing 1-2’ tall with petite periwinkle-colored flowers appearing along the stems. One of our most valued herbs for relaxing muscle tension and general anxiousness, this plant is used both to support sleep and simply find ease through the day. Cut back a few times over the season and dry for tea or infuse in alcohol to make a tincture. Skullcap doesn’t have much of a flavor, so it plays well with other aromatic family members like lemon balm, peppermint, and tulsi. 

Elecampane (Inula helenium): Do you ever wish your sunflowers had a little more sass and came back every year? Elecampane is your answer! Growing up to 6’ tall, elecampane sports finely-petaled yellow flowers born on thick bracts, with large clasping leaves that are a showstopper in the garden. Named after Helen of Troy, the root of this plant has been long revered as a pungent digestive tonic with a camphorous aroma that lends itself well to infused honeys and cordials. It’s valuable in supporting lung health and getting out stuck “gunk” wherever it may be lodged. 

California Poppy (Eschscholzia californica): We’re bringing back the California state flower to our collection this year. While related to the other garden poppies, Eschscholzia flowers later and requires far less in terms of soil quality to thrive. The only annual on this list, plant California poppy alongside other self-seeding annuals like chamomile and calendula, or tuck it around the front of a sunny perennial border that you don’t have time to mulch or fertilize. The whole plant is used medicinally, including the striking red root and attractive long seed pods (which also make excellent everlasting bouquet additions). Tincture the plant in vinegar or alcohol to make a tonic for sleep that is impeded by either pain or discomfort of body and mind alike.
