Description
Looking for a buttonbush with real character? Cephalanthus occidentalis is a great choice. This shrub is the North American buttonbush, a moisture-loving plant with glossy leaves and round, fragrant white flower heads in mid to late summer. The unusual spherical blooms are loved by bees and butterflies and are followed by button-like seed heads. Please note it is listed here among our maples for stock reasons but is a buttonbush, not a Japanese maple.

Where to plant Cephalanthus occidentalis
Cephalanthus occidentalis grows best in full sun or part shade, in moist to wet soil; it thrives beside ponds and in damp borders. It is a good choice for pond edges and damp borders, and also works well for wildlife gardens, bee-friendly planting and pond and stream edges. Plant with marginal and moisture-loving plants such as Iris sibirica, astilbes, ligularias and dogwoods.
How to plant Cephalanthus occidentalis
Give the pot a good soak first. Then dig a wide planting hole, enrich the soil with compost, and plant so the top of the root ball sits level with the ground. Firm in gently and water well, then add a mulch to hold in moisture.
How to care for Cephalanthus occidentalis
Keep the roots moist at all times, particularly in summer. A mulch of compost each spring helps to hold moisture. Cut back in late winter if needed and keep the roots moist in dry spells. Cut back in late winter or early spring if it needs shaping; it flowers on new growth, so pruning does not reduce the display. Usually trouble-free; dry soil is its main enemy.
Growing Cephalanthus occidentalis in a pot
Best in the ground in moist soil; in a container it needs constant watering.
