Blue Cohosh (Caulophyllum thalictroides)
A shy plant, these nonetheless will exhibit great vigor. We have received numerous reports of success, including flowering and fruiting within a year of transplant. Our plants for rootstock have attained large size. The dried root is a classic herb for increasing force of contractions during labor—a special ally in a woman’s garden.
Planting Blue Cohosh Roots: Best to plant dormant live roots in the fall for emergence in the spring. May be planted in woodlands, shade garden or in pots. Prefers dappled sunlight over complete shade. Grows best in woodlands under the shade of hardwood trees, not conifers. Choose a place with deep, humusy soil. Organic compost may be added to poor soil in order to improve growth of Blue Cohosh, but if the soil is already a deep forest loam then amending with compost is not necessary. Rake away existing mulch and plant root in the mineral soil, just below the surface, buds up, buds barely covered by mineral soil. Spread out rootlets below rhizome and tamp in firmly. Then cover with mulch, about 2 inches in all. Regular forest mulch, rotted leaves, or coir work well. Commercial bark mulch is not a good choice. Plant roots about 2 feet apart. Water once after planting, after which winter rain and snowfall will keep them sufficiently watered. The roots will overwinter under the mulch and the plant will emerge first thing in the spring. If during the spring and summer the planting becomes very dry (ie no rain for 2 weeks) then it is a good idea to water them. That is all the dare that is usually required. If potting up, use standard potting soil, one root per pot, gallon pot or bigger. Mulch on top of the pot and place in shade garden.

Hi, can blue cohosh be grown successfully in a Mediterranean climate? She came up well in the cool of early spring but the first dry heat wave (35c) has scorched all the leaves, despite being in the ground in a shady spot and under extra shade cloth for protection. Not sure if I have a weak plant and should get a stronger variety from you, or if blue cohosh just can’t handle the climate. Any advice?

Even in Appalachia, Blue Cohosh lives in the shadiest and coolest spots in the forest. However we grow it with great success here in a Z7 and we are indeed considered Mediterranean in climate–we grow it down by the creek where it receives only dappled sunlight, and we water during the late spring to summer, when 35 degrees C is considered rather cool, especiually in August! I do think you would have better luck with our very sturdy live roots and recommend them. Think yin, and mulch well with rotted leaves.

Hello, in October 2019, I planted the Blue Cohosh Live Root (Caulophyllum thalictroides) in a shady area as indicted. It took a long time to appear in the spring and was lovely although small. However the spot that I picked last October that seemed very shady was not that shady in the summer. Even though I kept it watered, it did not do well and eventually withered. I do not know if it is still alive. Would you recommend that I try and replant it in a different more shady spot soon, if there is still a root, or should I wait till spring? Thank you

Hi, I would recommend finding the root in the fall and transplanting it to an area of 100% shade–Blue Cohosh won’t withstand any more sun than dappled sunlight. Since your plant expressed, despite its early senescence, it has set bud, and needs a shadier spot. Mulch thickly.
