Description
An enchanting woodland perennial plant with flowers like no other, the Hillier Porcelain Blue Corydalis features a low mound of finely-cut blue-green foliage from which rises abundant clusters of dangling, vibrant aqua-blue flowers in spring repeating through summer and into fall. The honey scented tubular flowers are irresistible to butterflies and hummingbirds. Unlike other Corydalis, Hiller Porcelain Blue does not go dormant during summer. Foliage may take on a bronze cast during the heat of summer. Great for garden beds or containers in part shade to shade. One of those plants that will always have you looking forward to its bloom.
Landscape / Garden Uses
Growing 10 to 12 inches tall and 10 to 12 inches wide, Hillier’s Porcelain Blue Corydalis is ideal for use as an accent in shady small garden spaces or in groupings as a border in garden beds or along paths and walkways. Also excellent as a solo or combined with other plants in containers. A fine addition to shady woodland gardens, butterfly gardens, hummingbird gardens, blue theme gardens, cottage gardens, and perennial shade gardens.
In garden beds or containers, we like to combine Corydalis plants with Heuchera or Heucherella varieties, hosta lilies, perennial ferns and other part shade to shade loving plants and trees.
Suggested Spacing: 10 inches apart for mass plantings; 24 inches or more apart for space between plants

Growing Preferences
Corydalis are easy to grow in a consistently moist but well-drained soil of average fertility in shade to part shade. Some morning and evening sun is okay but avoid direct afternoon direct sun. Though it likers a consistently moist soil, as with so many other types of plants, it does not like a constantly wet or soggy soil. Plant with the top of the root ball even with ground level. Care and maintenance are minimal. Feed in spring with an organic plant food. No pruning necessary.
Plant Long & Prosper!
