Members of the Corydalis genus are low growing (15 to 60 cm) hardy annuals, bulbs or perennials that have leaves that look like those of ferns.
Depending upon the variety of Corydalis they may bloom at anytime form the early spring until the autumn, carrying tubular flowers of yellow or blue.
Some common names for Corydalis include Fumitory and Fumewort.
Corydalis ambigua by Arudhio.
It is quite difficult to grow Fumitory from seeds so you may prefer to grow from a plant from the garden centre.
If you prefer to grow your own fumitory then the seed should first be kept at a temperature of 17°C for 8 weeks, then chilled in the fridge for 2 weeks.
The seed should then be sown onto the soil surface when the temperature is at around 18°C.
Alternatively you can plant Corydalis (fumitory) bulbs at a depth of 7 cm at the beginning of the summer. Seeds or bulbs should be planted into a lightly shaded area of the garden with good drainage.
Ideally the soil that Corydalis grows in should be rich and of a pH 6 to 8.
It is important to cut back the plants after flowering as they are able to self seeds.
As they are difficult to grow from seed then you may wish to divide Corydalis perennials once flowering has finished.
The Corydalis genus includes approximately 470 species, most of them known for their delicate, fern-like foliage and tubular flowers.
Yes, Corydalis makes a lovely addition to woodland gardens, borders, and rock gardens. They add a touch of delicacy with their intricate foliage and blooms.
The most frequently grown species is Corydalis solida (Fumewort), loved for its early spring, colorful blooms.
Some species of Corydalis, such as Corydalis solida, produce a faint, sweet fragrance, particularly noticeable in warm, sunny conditions.
Corydalis prefer shady to semi-shady locations with well-drained, fertile soil. They are perfect for woodland or shade gardens.
Currently, Corydalis is not considered invasive in the USA. However, some species can self-seed under favorable conditions.
Removal of Corydalis involves hand-pulling the plant, making sure to remove the entire root system. Limiting self-seeding can also control its spread.
The Corydalis genus, part of the Papaveraceae family, originates from various regions across the Northern Hemisphere. These perennial plants, often grown in woodland gardens, are admired for their delicate, fern-like foliage and tubular flowers that bloom from late spring to early summer.
Corydalis prefer a shaded to partially shaded location with fertile, well-drained soil. They can be grown from seeds or tubers. Regular watering is necessary, especially during dry periods. However, these plants often go dormant in summer, so don't be alarmed if they seemingly disappear; they'll return in cooler weather.
