Black Cohosh - Actaea racemosa

Black Cohosh (Actaea racemosa) is a vigorous perennial with large, elegant spikes of white flowers and striking leaves. It is an easy-to-manage, perennial hardy plant that can tolerate partial to full shade conditions. They can be purchased at TN Nursery and will brighten up dark areas of your garden.

Black Cohosh Is Easy to Plant and Maintain

Planting them is easy and requires little effort. It loves moist, well-drained soil and prefers shade, such as woodland gardens or tree shelters. Once established, it is an excellent choice for busy or inexperienced gardeners due to its easy-to-care-for nature.

Black Cohosh Bloom Time and Color Changes

They typically flowers in late summer or early fall, between July and September. Its vertical flower spikes, filled with clusters of delicate white flowers, give a dramatic vertical accent to your garden. Flowering is weeks long, and the slight purplish color that comes later in the season adds another luscious touch late in the summer into fall.

Life Cycle and Longevity of Them

As a perennial, Black Cohosh will grow year after year, and you'll see it flourish in your yard for years with very little attention. It will occasionally spread and grow in small patches, and it is an excellent landscape plant. Because it is a perennial, it can flower reliably throughout its life.

Shape and Foliage

The plant is deep green in color, bushy and lobed, producing a full, neat mat. The flowers stand above the foliage to create a dramatic contrast.

Add TN Nursery's plants to your landscape, and you'll have an elegant, easy-care plant that will last.

Care

Black Cohosh prefers well-drained, rich soil. Keep the ground consistently damp but not saturated. It benefits from occasional feeding with a balanced fertilizer. Remove dead foliage to encourage new growth and protect it from harsh winter conditions.

Plant Reproduction

Black Cohosh spreads by dividing its rhizomes in the spring or fall.

Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.

Black Cohosh Roots

I planted my Black Cohosh roots in a shady pollinator garden
with lots of organic fertilizer and deep watering. I look forward to these
beautiful plants like white steeples in my summer garden.

Good Purchase of Black Cohosh

One of my students is a horticultural architect who designs garden installations in first floor office building space and rooftop apartments in NYC and the surroundings. She uses black cohosh often in her work and recommended I incorporate it into my meditation garden as feature plantings. The specimens came with a suggestion they be soaked in water for a while to wake them up before planting them. I'm in zone 5B, northern Berkshires of MA, and these were 5B rated. I just put them in the ground (8), and will be watching with great anticipation next spring for growth.

Speedy and good quality.

I ordered Black Kohosh and they arrived promptly and well packaged. Got them in the ground right away thanks to the instructions that came with. Will definitely order from TN again - good products! Looking forward to my plants coming up in the Spring.

Timely shipping

The roots were shipped and arrived promptly. They look really healthy and I planted them in pots since I don't have my garden place quite ready.
Thanks for the good service

Bare-rooted Black Cohosh plants

Arrived on time and in very good condition. Literature was included on planting bare-rooted perennials and other plants. I planted them as soon as they arrived in one of my raised beds in a somewhat shady area. Would purchase again from TN nursery as they have a very good website with lots of information and I am very satisfied with the condition of the plants I received.
