Product Description
Platycodon 'Astra Double Blue'
Common Name: Balloon Flower.
Zones 3 to 8.
Full sun to part shade.
Plants reach 8 to 10 inches tall and 6 to 8 inches wide.
Growth rate: Moderate, herbaceous clump-forming perennial.
Blossoms swell into balloon-like buds before they burst open into fully double, bell-shaped flowers. Exceptional branching and thick flower petals make for long-lasting periwinkle blue blossoms. Its compact, uniform habit makes 'Astra Double Blue' a good selection for cut flowers, containers, or the garden. Deadheading generally prolongs the bloom period.
Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
