How to Grow and Care for Fumeworts
Feedback
Fumeworts thrive in partially shaded areas with cool, moist conditions and well-drained soil. For basic care, they require dappled light and consistent moisture without waterlogging. They prefer cooler temperatures and are sensitive to heat. Common challenges for fumeworts include root rot, powdery mildew, and aphid infestations. Seasonally, fumeworts may go dormant in summer heat, requiring less water. In autumn, they benefit from mulching for winter protection. Spring is their active growth period, necessitating attentive watering and protection from late frosts.

8 most common species：
Incised fumewort
An unwelcome intruder, incised fumewort spreads rapidly through its seeds, which are dispersed from the plant and launched far and wide. It grows quickly and crowds out native plants growing in the woodland understory. This plant is not commonly sold in nurseries in the United States, but has been naturalized and grows along the east coast. It has purple, tube-shaped flowers, which many find attractive, but caution should be taken in planting the incised fumewort due to its invasive nature.
Bird in a bush
Bird in a bush (Corydalis solida) is native to northern Europe and Asia and is widely cultivated for its attractive ferny leaves and long flowers that come in various shades of purple, mauve, red, and white. It is an ephemeral woodland plant, only appearing in spring and then dying back to its tuberous root in the summer.
Hollowroot
A flowering plant, hollowroot is native to Europe. Its flowers can be purple, red, or white with long spurs. These plants flower in the spring and go dormant in the summer. Ants are known to collect the seed and transport them into their colonies.
Scrambled Eggs
The scrambled Eggs (Corydalis aurea) is an annual or biennial wildflower that is indigenous to North America. It blooms with yellow flowers during the spring. This species prefers moist soil.
Japanese false bleeding heart
Japanese false bleeding heart is a flowering plant from the genus Corydalis, which translates from Greek as "Crested lark" (bird). The yellow flowers with brown-purplish tips resemble snapdragons and grow in attractive clusters; however, the entire plant has a distinctly unpleasant smell. The odor may be the reason why deer and rabbits won't touch it; on the other hand, it is enjoyed by pollinating insects and hummingbirds.
Yellow fumewort
Yellow fumewort is a flowering perennial native to the eastern United States. This plant grows mainly in disturbed grounds and floodplains. Its existence is threatened by land development such as lawns. This plant has a high alkaloid content, which likely makes it toxic.
Scouler's fumewort
Scouler's fumewort (Corydalis scouleri) is native to British Columbia, Washington and Oregon in North America, where it can form dense colonies in moist, wooded habitats. Its clumps of lush, lacy foliage and hot pink summer flowers make it ideal for garden borders. The plant was named after Dr. John Scouler, an explorer of the Pacific Northwest.
Corydalis
Corydalis flexuosa is a species of flowering plant in the genus Corydalis, of the family Papaveraceae. It is a shade-loving perennial originating in woodland and mountainous areas of China. Growing to 30 cm, in spring it produces masses of bright blue tubular flowers with a white throat. It is summer dormant, meaning that the foliage dies down in summer. This plant is widely cultivated. It is hardy to USDA zones 5–8. The cultivars 'Blue Panda' and 'Purple Leaf' have gained the Royal Horticultural Society's Award of Garden Merit.

Dracaena
Dracaena are popular house plants that are easy to grow. They can tolerate low-light conditions and require little watering. Their leaves range from variegated to dark green. Their characteristic traits include woody stems that grow slowly but offer a striking appearance for small spaces such as apartments or offices.
Fig trees
Fig trees have been cultivated in many regions for their fruits, particularly the common fig, F. carica. Most of the species have edible fruits, although the common fig is the only one of commercial value. Fig trees are also important food sources for wildlife in the tropics, including monkeys, bats, and insects.
Brambles
Brambles are members of the rose family, and there are hundreds of different types to be found throughout the European countryside. They have been culturally significant for centuries; Christian folklore stories hold that when the devil was thrown from heaven, he landed on a bramble bush. Their vigorous growth habit can tangle into native plants and take over.
Maples
The popular tree family known as maples change the color of their leaves in the fall. Many cultural traditions encourage people to watch the colors change, such as momijigari in Japan. Maples popular options for bonsai art. Alternately, their sap is used to create maple syrup.
Prunus
Prunus is a genus of flowering fruit trees that includes almonds, cherries, plums, peaches, nectarines, and apricots. These are often known as "stone fruits" because their pits are large seeds or "stones." When prunus trees are damaged, they exhibit "gummosis," a condition in which the tree's gum (similar to sap) is secreted to the bark to help heal external wounds.
Nightshades
Nightshades is a large and diverse genus of plants, with more than 1500 different types worldwide. This genus incorporates both important staple food crops like tomato, potato, and eggplant, but also dangerous poisonous plants from the nightshade family. The name was coined by Pliny the Elder almost two thousand years ago.
Roses
Most species of roses are shrubs or climbing plants that have showy flowers and sharp thorns. They are commonly cultivated for cut flowers or as ornamental plants in gardens due to their attractive appearance, pleasant fragrance, and cultural significance in many countries. The rose hips (fruits) can also be used in jams and teas.
Oaks
Oaks are among the world's longest-lived trees, sometimes growing for over 1,000 years! The oldest known oak tree is in the southern United States and is over 1,500 years old. Oaks produce an exceedingly popular type of wood which is used to make different products, from furniture and flooring to wine barrels and even cosmetic creams.
