Rue Anemone

Year-round

Rue anemone is a small, early spring woodland wildflower that is native to Ohio and much of the eastern United States, and it goes fully dormant by early summer so it disappears from the bed until the following spring.

• Native to Ohio's deciduous woodlands, found on wooded slopes and ridges throughout the state, per the Lady Bird Johnson Wildflower Center
• Grows well under 12 inches tall, in part to full shade with humus rich, evenly moist but well drained, slightly acidic soil
• A true spring ephemeral, it flowers in April and May, sets seed by mid-May, then dies back to the ground until the following spring
• Spreads slowly by tuberous roots and self seeding, staying well behaved rather than aggressive
• Best planted under tall deciduous trees and avoid planting near black walnut trees
• Rabbits and other herbivores will browse young growth, so new plantings may need protection

Goes fully dormant and disappears by early summer, so the bed stays tidy on its own without any cutback work, which reads as intentional rather than overgrown.

Fall

Rue anemone stays dormant through fall with nothing happening above ground, which makes fall a good time to plant new divisions or nursery starts.

• Best planted in fall, or very early spring, so roots can establish before next year's brief growing window
• Top dress with shredded leaf litter in fall to mimic the humus rich woodland floor it needs
• No need to cut back or clean up, since there is no visible foliage this time of year
• Columbus's first fall frost typically arrives around mid October, which does not affect this already dormant plant

Winter

The plant is fully dormant underground through winter and needs no care at all.

• Tuberous roots overwinter in the soil with no maintenance required
• A layer of fallen leaves left in place over winter protects the dormant roots and adds organic matter
• Hardy through Columbus's USDA zone 6b winters with no special protection needed
• Nothing to prune or water during dormancy

Spring

Spring is when rue anemone does all of its growing, blooming, and seed setting before going dormant for the year.

• Emerges in early to mid April in the Columbus area, before deciduous trees fully leaf out
• Flowers open white to pale pink from mid April through May
• Water new spring plantings well while they establish, since the plant does most of its yearly growth in these few weeks
• Let seed pods mature and drop before the foliage yellows if you want the patch to slowly spread over time
• No fertilizer needed if planted in humus rich woodland soil

Summer

By early summer the plant has gone dormant and the foliage disappears completely, so there is nothing to water or maintain.

• Foliage yellows and dies back by late May to June as central Ohio warms up
• Mark the spot if the bed is otherwise bare, since there is no visible plant from June through the rest of the growing season
• No supplemental water needed once it is dormant, since the plant is not actively growing
• Avoid digging or disturbing the soil where it is dormant so the tuberous roots are not damaged
