WaterFumewort should be watered thoroughly, ensuring that the soil is moist but not waterlogged. During the growing season, especially in dry spells, watering may be required every few days, with about 16 ounces of water per square foot. In cooler months or when the plant is dormant, reduce watering to prevent rot, providing only enough water to prevent the soil from completely drying out.
LightFumewort thrives best in partial shade to dappled sunlight. The ideal location for this plant would be in a garden that offers protection from the harsh afternoon sun, as too much direct sunlight can lead to leaf scorch, while too little can decrease flowering.
TemperatureFumewort prefers cooler temperatures and will thrive in temperatures between 50 and 65 degrees Fahrenheit. It can tolerate a minimum temperature of around 30 degrees Fahrenheit but should be protected from hard freezes. The plant might struggle in areas where the summer temperatures regularly exceed 75 degrees Fahrenheit.
PruningPruning fumewort isn't typically necessary, but you may remove spent flowers or damaged foliage to maintain plant appearance. This light pruning can be done as needed throughout the growing season. Cutting back the foliage after flowering helps to encourage a second bloom.
CleaningAs needed

RepottingFumewort should be repotted every 2 to 3 years or when it outgrows its pot. Spring is the best time for repotting to minimize stress on the plant.

Life cycleCorydalis 'Korn's Purple', also commonly known as Korn's Purple corydalis, begins its life as a seed that germinates in spring, with the appropriate moisture and temperature conditions. Once the seedlings establish, they grow into clumps of feathery, blue-green foliage from which delicate, tubular purple flowers emerge, typically in mid to late spring. After flowering, the plant sets seed which is dispersed by various means, including wind and rain. Throughout the summer, the plant continues to grow vegetatively, although it may enter dormancy during periods of drought or high heat. As a perennial, Korn's Purple corydalis will die back to the ground in fall with the first frosts, with its root system lying dormant through the winter. In the following spring, the plant will regenerate from its rootstock, completing the cycle and beginning again with fresh growth.
PropogationPropogation time
Early Spring
The most popular method of propagation for Corydalis 'Korn's Purple', which is commonly known as the fumewort, is by division. This technique is typically carried out in the fall or early spring when the plant is dormant or just beginning to grow. To propagate by division, carefully dig up the fumewort, ensuring minimal disturbance to the roots. Gently tease apart the clumps of roots into smaller sections, each with several growth points. Replant the divisions at the same depth they were growing previously, spacing them about 10 to 12 inches (approximately 25 to 30 centimeters) apart to allow ample room for growth. Water the newly planted divisions well to help establish them. This method allows gardeners to quickly increase their stock of Corydalis 'Korn's Purple' while ensuring the new plants are true to the parent's characteristics.
