Landscape Attributes

Hillier™ Porcelain Blue Corydalis is a dense herbaceous evergreen perennial with a mounded form. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Hillier™ Porcelain Blue Corydalis is recommended for the following landscape applications;

• Rock/Alpine Gardens
• Border Edging
• General Garden Use
• Naturalizing And Woodland Gardens

Planting & Growing

Hillier™ Porcelain Blue Corydalis will grow to be about 10 inches tall at maturity, with a spread of 12 inches. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. As an evegreen perennial, this plant will typically keep its form and foliage year-round.

This plant should be grown in a location with partial shade or which is shaded from the hot afternoon sun. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
