Pink Spike Bugbane
Pink Spike Bugbane
Dark Foliage and Fragrant Pink Fall Spires
Pink Spike Bugbane (Actaea simplex 'Pink Spike') pairs deeply cut, dark purple-bronze foliage with tall, fragrant bottlebrush spires that open pink-flushed in late summer and fall. The dramatic dark leaves anchor the shade garden all season, while the sweetly scented late flowers feed pollinators when little else blooms. Deer-resistant and reliably hardy, it brings height and fragrance to moist, shaded borders in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Dramatic shade backdrop: The dark foliage and tall pink-tinged fall spires make a bold accent at the back of a shaded border. Space 2–3 feet apart.
Late-season pollinator and rain gardens: The fragrant fall flowers feed late bees and butterflies, and it loves moist rain-garden soil. Pair with hostas, ferns, and astilbe.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall (late August–mid September) into rich, moist, shaded soil. Keep consistently moist.
How to Plant Pink Spike Bugbane
Dig a hole twice the root ball width at the same depth, mixing in plenty of compost. Set the crown level, backfill, water well, and mulch 2–3 inches deep. Space 2–3 feet apart in a spot that stays moist.
Watering Pink Spike Bugbane

After year one: Continue steady moisture, especially in any sun. It performs best in cool, rich, moist shade.
