Balloon Flower vs Lacecap Hydrangea Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Balloon Flower
Platycodon grandiflorus
Platycodon grandiflorus, commonly known as Balloon Flower, is a herbaceous perennial prized for its distinctive balloon-shaped flower buds that open into star-shaped, bell-like flowers. Typically grown outdoors in gardens, it reaches a height of 1 to 3 feet. The plant features blue, pink, or white flowers, blooming in summer. While it can be grown indoors, it requires very bright light and careful attention to watering. People grow it for its unique flower shape and long-lasting blooms in borders, cottage gardens, and cut flower arrangements.
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.
