The balloon flower, also known as platycodon grandiflorus, is a perennial plant that produces beautiful flowers in shades of pink, blue, and white. The name “balloon flower” comes from the unopened flower buds, which look like hot-air balloons. These clump-forming plants have light green leaves and can grow up to three feet tall.

To grow balloon flowers, it’s important to plant them in moist, well-drained soil and in an area with full sun or partial shade. While they prefer cooler summers, they can still thrive in other areas. It’s important to mark the plant’s position, as spring growth can be slow to appear. Propagation can be done through division or by seed indoors or outdoors.

These flowers bloom for most of the summer and are perfect for borders or along garden edges. There are several related varieties available, including the dwarf Fuji White, the blue-flowered Mariesii, and the soft-pink Shell Pink.
