Product Details

Featuring dark blue, balloon-like buds that open into 3"-diameter, violet-blue flowers with extra thick petals that extend the duration of the blooms, compact Platycodon grandiflorus ‘Astra Blue’ makes an enchanting addition to garden beds and container plantings. The neatly mounding, sturdy, well-branched plants have finely textured foliage that remains dark green throughout the heat of summer. One of the Astra series of Balloon Flowers.

Native to meadows and hillsides in China, Japan, Korea and Siberia, clump-forming Balloon Flower derives its common name from balloon-like flower buds that open into five-pointed, bell-shaped flowers that face upward or outward. Plants in this genus like well-drained soil rich in organic material. Compact P. grandifloras ‘Astra Blue’ features dark blue buds that burst into 3"-diameter, violet-blue flowers. It makes an enchanting addition to gardens and containers.

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it.

Latin Name Pronunciation: plat-ee-ko'don  

Plant in full sun or partial shade in a spot with well-drained soil rich in organic matter. This summer bloomer may be slow to become established, especially in heavy soil. Because plants are very late in sending up new growth in spring, mark their location to avoid digging into the fleshy roots. Deadhead plants to encourage repeat bloom.
