Button Bush vs Lacecap Hydrangea Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Button Bush
Cephalanthus occidentalis
Buttonbush is a deciduous shrub or small tree typically found in wet habitats like swamps, floodplains, and along streams. It grows to a height of 3-12 feet. Its most distinctive feature is its spherical flower heads, resembling buttons, composed of numerous tiny, creamy-white flowers. These flowers attract pollinators. While primarily an outdoor plant, it is sometimes grown indoors as a novelty, but requires very specific conditions to thrive. People grow it for its unique appearance and wildlife value.
Lacecap Hydrangea
Hydrangea macrophylla 'Lacecap'
Lacecap Hydrangeas are deciduous shrubs known for their distinctive flower heads. They feature a central cluster of tiny, fertile flowers surrounded by a ring of larger, showy sterile flowers. This creates a delicate, lace-like appearance. Typically grown outdoors in gardens and landscapes, they offer beautiful blooms in shades of pink, blue, or white, depending on the soil pH. They are not naturally indoor plants and require specific conditions to thrive indoors, making them a challenging choice for indoor cultivation.

However, in hotter climates, some afternoon shade can be beneficial to prevent leaf scorch. Partial shade, meaning 4-6 hours of direct sunlight, is also acceptable, especially in warmer regions.
How do I care for Button Bush?
Button Bush thrives in consistently moist to wet conditions, so regular watering is essential, especially during dry periods. Aim for at least 1-2 inches of water per week. Plant in full sun to partial shade, ideally in a location that receives at least 6 hours of sunlight per day. Button Bush tolerates a wide range of soil types, but prefers slightly acidic, well-draining soil.
