Welcome to the first of our blog series on herb gardening! Garden medicinal plants and culinary herbs can be challenging, exciting, and rewarding! It is a wonderful way to be able to provide your own medicine and secure alternative sources for certain plants that may be endangered, have small populations, or are otherwise difficult to find in the wild. Some medicinal plants absolutely thrive in gardens with just a little attention! Many of our medicinal plants are perennials, which means they return to our gardens year after year.
Because it is Spring and the Medicinal Plant Sale is around the corner, we wanted to provide you with some information about some common medicinal plants that you can grow in your garden. In fact there are hundreds of medicinal plants that you can plant in your garden! In future blog posts, we’ll talk about Montana native plants, pollinator plants, and culinary herb gardening.
For this first post, we’re focusing on non-native-to-Montana plants that can be grown fairly easily here. Most of these plants starts and seeds are available by western Montana growers; many will be available at the upcoming plant sale behind Meadowsweet. Supplies are limited; to pre-order or find out more information about the producers or event sponsors, check out the Facebook event page! You can also check out local stores like Caras Nursery for medicinal/native plant starts or find high quality seeds online at Strictly Medicinal Seeds.
Without further ado, here are some plants to try out in your garden!

COMFREY (Symphytum officinale)
Description / Growing Habits / Harvest: Comfrey is a perennial that likes deep, rich, moist soils and full sun. Plant in a place you can live with it, as it is grows large and is hard to dig up (and therefore is difficult to kill!) There are two varieties: one spreads by seed, the other creeps.

Any of these preparations can be applied to the skin to heal rashes, eczema, or other skin eruptions. (DO NOT USE on open wounds, as it can heals skin so quickly that it traps in bacteria). It is also a deep healer; it can be applied topically to ease pain, inflammation, and rheumatic complaints like arthritis. Also called “knitbone,” Comfrey contains the compound allantoin, which helps cells proliferate , thus encouraging bone healing. There is controversy about whether comfrey should be used internally, due to potential liver damage, but when used externally it is very safe.*

Common / Historical Uses: The flowers have historically been used for their anti-inflammatory, pain-relieving, and calming effects. They can be put into salve for topical wound healing or added into a tea, kombucha, or beer. The taste is too strong for some, so it can be added alongside other herbs or flavors.

Common / Historical Uses: You can make a tincture with the fresh flowers, leaves. A tea is best avoided as this plant tastes very bitter.

This plant is a mild vaso-dilator, so while it can help folks with mildly high blood pressure, folks with low blood pressure or low thyroid function should avoid using it.*
