Blue Panda Corydalis flexuosa 'Père David'
ABOUT
Corydalis flexuosa 'Père David', commonly known as 'Golden Blue Corydalis', is a herbaceous perennial known for its ornamental qualities. The plant displays delicate, fern-like, blue-green foliage that creates a soft, feathery texture in garden beds. The leaves are divided into smaller leaflets, which in turn are sub-divided to give a finely dissected appearance. One of the most striking features of the Golden Blue Corydalis is its blooms. The flowers emerge in spring and can continue through summer, presenting a remarkable display of vivid, electric blue blossoms. These tubular flowers are slightly curved, resembling a spur at the back, and are clustered atop slender, arching stems, gracefully rising above the foliage. The color contrast between the bright blue flowers and the cool green leaves makes this plant particularly eye-catching. It typically blooms profusely, creating a carpet of color that can enliven shady spots in the landscape. As a perennial, the Golden Blue Corydalis will die back in the winter only to re-emerge with its elegant foliage and charming flowers in the spring, offering a yearly spectacle that enhances woodland settings or shade gardens. It is cherished not only for its beauty but also for its ability to adapt and thrive in dappled shade conditions, where many other colorful plants might struggle.

WaterBlue corydalis benefits from regular watering, especially during dry spells, receiving about one inch of water weekly. Water the plant thoroughly to encourage deep root growth, but avoid waterlogging as it prefers well-drained soil. It's best to apply water directly to the base of the plant rather than overhead sprinkling to minimize the risk of leaf diseases. In hot, dry weather, increase watering frequency to prevent the soil from drying out completely. During the winter months, reduce watering as the plant requires less moisture.
LightBlue corydalis thrives in partial shade, preferably receiving morning sunlight and afternoon shade. The ideal spot for this plant would be a location that is shielded from the intense heat of the midday sun, which can scorch the delicate foliage. Adequate light is essential for optimal growth and flowering, but too much direct sunlight can be harmful.
TemperatureBlue corydalis prefers cool to moderate temperatures, with ideal growth occurring between 50°F and 70°F. The plant can tolerate temperatures as low as 20°F but may suffer if exposed to prolonged periods of frost or temperatures below this threshold. Conversely, high temperatures above 80°F can lead to dormancy; therefore, it is important to provide a cool environment, especially during summer.
PruningBlue corydalis does not typically require extensive pruning, but deadheading spent flowers can encourage a second flush of blooms. Trim away any yellowed or dead foliage to maintain plant health and aesthetics. Pruning is best done after the first flowering in late spring or early summer.
CleaningAs needed
SoilThe Blue Panda Corydalis thrives in rich, moist, well-drained soil with high organic content. A mix of loam, compost, and a small amount of sand can provide the texture and nutrients necessary for its growth. The ideal soil pH for Blue Panda Corydalis should be slightly acidic to neutral, ranging from 6.0 to 7.0.
RepottingBlue Panda Corydalis does not usually require frequent repotting and can be left undisturbed for several years. It should be repotted only when it has outgrown its current container, which may be every 2-3 years.
Humidity & MistingBlue Panda Corydalis prefers a moderately humid environment, mimicking its native woodland habitat. Aim for a humidity level around 50-60% for the best growth, without the need for special humidity control in typical household conditions.

Life cycleThe Blue Panda Corydalis (Corydalis flexuosa 'Père David') starts its life cycle when seeds germinate in the spring, requiring moist, cool conditions to successfully sprout. After germination, seedlings establish themselves and form a clump of fern-like, blue-green foliage. Flowering begins in late spring to early summer, producing clusters of brilliant blue, tubular flowers that attract pollinators. Following pollination, the plant sets seed, which completes its reproduction cycle; these seeds may lie dormant until the next spring. The Blue Panda Corydalis is a perennial plant, meaning it dies back to the ground in winter and re-sprouts from the rootstock in spring. Over time, the plant can slowly spread and colonize an area, thanks to its self-seeding ability and rhizomatous growth habit.
PropogationPropogation time
Spring to early summer
Corydalis flexuosa 'Père David', commonly known as Chinese Blue Corydalis, is most commonly propagated through division of its tubers. This should ideally be done in the fall, after the foliage has died back, or in early spring before growth resumes. To propagate by division, dig up the plant carefully, preserving as much of the root system as possible. Gently separate the tubers, making sure each division has at least one growth bud. Replant the divisions immediately at the same depth they were growing previously, allowing about 12 inches (approximately 30 centimeters) between plants to ensure adequate space for growth. Water the newly planted tubers well to help establish them. This method allows the plant to recover and start new growth with the onset of the next growing season.
