Frequently Asked Questions

Everything you need to know before you sow.

Why are Platycodon flowers called balloon flowers?

The unopened flower buds swell into rounded, balloon-like shapes before opening into five-pointed star-shaped flowers.

Can Balloon Flower plants stay in the same spot for several years?

Yes. Platycodon grandiflorus is a perennial, so established plants can return in suitable growing conditions.

What happens if Balloon Flower buds are picked before opening?

The rounded buds are a distinctive feature, but flowers intended for display are generally allowed to open fully for their star-shaped appearance.

Does Balloon Flower need support in a garden border?
Its upright growth is generally self-supporting, though exposed sites or tall, heavily flowering stems may benefit from light support.

Can Platycodon be divided after it becomes established?

Established perennial clumps can be divided, although care is needed because the plant develops a substantial root system.

Can the mixed seed pack produce different flower colours?

Yes. The mix includes blue, pink and white flower forms, so plants can show different bloom colours.
