How to Grow and Care for Jacobaea
Feedback
Jacobaea is a low-maintenance plant genus with simple needs. They need full sunlight and well-drained soil, preferring moderate water and a temperate climate. Overwatering and poor soil drainage are challenges, leading to root rot and pest infestation like aphids and snails. Seasonally, its growth may decline during winter, requiring lesser water and protection from frost. Pruning is recommended post-flowering in spring. Jacobaea’s adaptive nature makes it a resilient presence in gardens. Care must be guided by seasonal changes and local environmental conditions.

8 most common species：
Tansy ragwort
Tansy ragwort is a biennial that is classified in many areas of the United States as a noxious weed. The tansy ragwort is poisonous to livestock, pets, and humans. This plant is found in sunny open areas like pastures and meadows. It has bright yellow flowers and grows 61 to 122 cm tall.
Silver ragwort
Silver ragwort (Jacobaea maritima) is a very white-wooly, heat and drought tolerant evergreen subshrub native to the Mediterranean region. This species was formerly known as Senecio cineraria. Some species of bees build nests on silver ragwort's leaves. This species is deer resistant and often cultivated for horticultural purposes.

Water ragwort
Water ragwort is a species in the daisy family whose clusters of tiny yellow flowers give it a distinctive appearance. As its common name Water Ragwort suggests, it favours wet habitats.
Aleutian ragwort
Flourishing in nutrient-rich and moisture-laden habitats, aleutian ragwort produces seeds that are spread by the wind. It has been observed that its leaves appear similar to hemp leaves. Aleutian ragwort has been used as an ingredient in moisture preserving cosmetics and has been used for a variety of medicinal purposes.
Great fen ragwort
The marsh cross herb (Jacobaea paludosa basioniem: Senecio paludosus) is a plant from the composite family (Asteraceae). The plant can reach a height of approximately 1.8 m. The species grows in floodplains and on banks. The plant blooms in summer.
Hoary groundsel
Hoary groundsel is found in grassland, hedgebanks, and alongside roads. It has vibrant flowers that boast the characteristic appearance of a dandelion.
Grey ragwort
Grey ragwort is a daisy species found growing in stony terrain, including rocky meadows and moraines. It produces clusters of vibrant yellow blooms, dandelion-like in appearance. It was given its common name, "grey ragwort," for the grey coloration of its foliage.

Tansy ragwort
Tansy ragwort
Tansy ragwort (Jacobaea vulgaris subsp. vulgaris) is native to Eurasia and has become naturalized in North America as well. Tansy ragwort is usually considered a weed, and can be hard to control in areas of disturbed soil. Alkaloids in the tansy ragwort plant make it relatively toxic to humans and livestock.
Ragwort
Ragwort
It is a creeping perennial with a tufted strain. The stem reaches a size of 3 to 7 cm tall, erect, hard, soft. The glabrous and bi or tri-pinnate leaves with very narrow linear, almost filiform subdivisions, the petiolate lower leaves, the sessile upper ones. Inflorescence in umbels with ovoid involvement. The yellow flowers
Marsh ragwort
Marsh ragwort
Marsh ragwort (Jacobaea aquatica) is a biennial flowering herb found primarily in wet grassland. Its yellow flowerheads are borne in loose flat-topped clusters. The plant is mildly toxic to cattle and can cause issues in wet hay meadows used for grazing. Still, marsh ragwort is a valued part of ecosystems and provides food for a variety of moths and butterflies.
Pinnate-leaved ragwort
Pinnate-leaved ragwort
Pinnate-leaved ragwort is a perennial herb known for its silver-gray, feathery foliage reminiscent of wormwood and aromatic qualities. Typically found in rocky, subalpine areas, pinnate-leaved ragwort thrives in well-drained soil and adapts to sun or partial shade. Its small, yellow flower heads bloom in clustered arrays, attracting pollinators while serving as a hardy, drought-resistant species in its native mountainous habitats.
Jacobaea erucifolia subsp. argunensis
Jacobaea erucifolia subsp. argunensis
Jacobaea erucifolia subsp. argunensis is a robust, herbaceous perennial known for its silver-green, deeply lobed leaves that resemble rocket (arugula). This subspecies typically thrives in open, gravelly areas, adapting to sun-exposed conditions. Its bright yellow flowers, clustered into dense, flat-topped inflorescences, make it a distinctive sight during its summer bloom.
Jacobaea pseudoarnica
Jacobaea pseudoarnica
Jacobaea pseudoarnica exhibits bright yellow, daisy-like flowers atop tall stems, reminiscent of its sun-loving counterparts. Despite its standout blooms, it thrives in alpine meadows, adapting to softer soils and cooler climates. The deep green leaves are oblong with slight serration, contributing to a rugged yet appealing aesthetic.

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.
