Overview of Golden Chain Tree
Golden chain tree, also known as Laburnum x watereri, is a small ornamental tree or shrub that is primarily grown for its showy pendulous flowers. It is a hybrid species that is a cross between Laburnum alpinum and Laburnum anagyroides.
The tree is best grown in zones 5 to 7 and generally requires full sun to partial shade and well-drained soil. It can grow up to 20 feet tall and wide, but can also be pruned to maintain a smaller size.
Golden chain tree is known for its very showy pendulous flowers that can grow up to 16 inches in length. The flowers bloom in May and are bright yellow in color, resembling chains of gold. The tree also produces papery lantern-like fruits that are not edible.
The tree is a popular choice for landscaping and is often used as a specimen tree in gardens, parks, and public spaces. It is also used as a flowering accent tree in mixed borders or as a small shade tree.
In addition to its ornamental value, golden chain tree has also been studied for its potential medicinal properties. Studies have shown that extracts from the tree’s leaves may have antioxidant and anti-cancer properties. However, further research is needed to fully understand the potential health benefits of golden chain tree.
Overall, golden chain tree is a beautiful and versatile tree that can add a pop of color and interest to any landscape. Its vibrant yellow flowers and attractive foliage make it a popular choice for homeowners and landscapers alike.

Cultivation and Care
If you want to grow a Golden Chain Tree in your garden, you need to make sure that you provide the right conditions for it to thrive. Here are some tips for cultivating and caring for this beautiful tree:
Golden Chain Trees prefer well-drained soil with good drainage, so make sure that you plant it in a location with good drainage. They also prefer full sun to partial sun, so make sure that the location you choose gets plenty of sunlight. The ideal time to plant a Golden Chain Tree is in early spring or fall.
Golden Chain Trees prefer slightly acidic to neutral soil with a pH between 6.0 and 7.5. If your soil is too alkaline, you can add some sulfur to lower the pH. If your soil is too acidic, you can add some lime to raise the pH. You can also enrich the soil with compost or fertilizer before planting to help the tree grow.
Golden Chain Trees like moist, well-drained soil, so make sure that you water them regularly. However, be careful not to overwater them, as they don’t like standing water. It’s best to water them deeply once a week, rather than giving them frequent shallow watering.
Golden Chain Trees don’t need a lot of fertilizer, but you can give them a boost by fertilizing them once a year in early spring. Use a balanced fertilizer that is high in nitrogen to encourage growth.
Golden Chain Trees don’t need much pruning, but you can prune them in late winter or early spring to shape them and remove any dead or damaged branches. You can also take hardwood cuttings in the fall if you want to propagate the tree.
If you’re growing a Golden Chain Tree in a container, you may need to repot it every few years to give it more space to grow. Choose a well-draining potting mix and make sure that the pot has drainage holes to prevent waterlogging.
Golden Chain Trees are susceptible to sunscald, which is a condition where the bark is damaged by the sun. To prevent sunscald, wrap the trunk of the tree with a light-colored tree wrap in the winter.
Golden Chain Trees bloom in the late spring or early summer, producing long chains of bright yellow flowers. The blooming period lasts for several weeks, and the tree can be quite stunning when in full bloom.
By following these tips, you can cultivate and care for a beautiful Golden Chain Tree in your garden.
If you want to propagate Golden Chain Trees, you have several options available. This section will cover some of the most popular methods for propagating Golden Chain Trees.
Propagating by Seeds
One of the most common methods of propagating Golden Chain Trees is by using seeds. You can collect the seeds from the pods that develop on the tree after it flowers. Once you have collected the seeds, you can plant them in a pot or directly in the ground. If you decide to plant them in a pot, make sure that the pot has drainage holes and that you use well-draining soil. Keep the soil moist, but not waterlogged, and place the pot in a warm, sunny location.
Propagating by Cuttings
Another method of propagating Golden Chain Trees is by using cuttings. To do this, take a cutting from the tree during the spring or summer months. The cutting should be about 6 inches long and have several leaves on it. Remove the leaves from the bottom half of the cutting and dip the cut end into rooting hormone. Plant the cutting in a pot filled with well-draining soil and keep it moist. Place the pot in a warm, sunny location and wait for the cutting to root.
If you plan to grow your Golden Chain Tree in a pot, make sure that the pot is large enough to accommodate the tree’s root system. Use a potting mix that is well-draining and contains a mix of peat moss, perlite, and vermiculite. Water the tree regularly, but make sure that the soil is not waterlogged. Fertilize the tree with a balanced fertilizer every month during the growing season.
Tips for Successful Propagation
Regardless of which method you choose, there are a few things that you can do to increase your chances of success. Make sure that the soil is well-draining and that you keep it moist. Provide the tree with plenty of sunlight and warmth, and fertilize it regularly during the growing season. With a little patience and care, you can successfully propagate your own Golden Chain Tree.
While the golden chain tree is generally a hardy and low-maintenance tree, there are a few potential problems that you should be aware of.
Blight is a fungal disease that can affect the golden chain tree, causing leaves to turn brown and fall off prematurely. To prevent blight, make sure your tree is planted in well-draining soil and avoid overwatering. If you notice signs of blight, remove infected branches and dispose of them properly.
Canker is another fungal disease that can affect the golden chain tree. It causes sunken areas on the bark and can lead to dieback of branches. To prevent canker, make sure your tree is planted in well-draining soil and avoid damaging the bark. If you notice signs of canker, remove infected branches and dispose of them properly.
Leaf spot is a common fungal disease that can affect the golden chain tree. It causes small brown spots on the leaves, which can eventually lead to defoliation. To prevent leaf spot, make sure your tree is planted in well-draining soil and avoid overhead watering. If you notice signs of leaf spot, remove infected leaves and dispose of them properly.
Aphids are small insects that can infest the golden chain tree, sucking sap from the leaves and causing them to curl and distort. To prevent aphids, encourage natural predators like ladybugs and lacewings, and avoid using pesticides that can harm beneficial insects. If you notice signs of aphids, spray the tree with a strong jet of water to dislodge them.
Mealybugs are another common pest that can infest the golden chain tree, leaving behind a white, cottony residue on the leaves and branches. To prevent mealybugs, encourage natural predators like ladybugs and lacewings, and avoid using pesticides that can harm beneficial insects. If you notice signs of mealybugs, remove infected branches and dispose of them properly.
Toxicity and Safety
The Golden Chain Tree is a beautiful ornamental tree that is popular in many gardens. However, it is important to be aware that all parts of this tree are poisonous. The tree contains a toxic compound called cytisine, which can be harmful to humans and pets if ingested.
Symptoms of Golden Chain Tree poisoning in humans can include vomiting, diarrhea, and convulsions. In severe cases, it can even lead to death. Therefore, it is essential to keep the tree away from children and pets.
If you suspect that you or someone you know has ingested any part of the Golden Chain Tree, seek medical attention immediately. Do not induce vomiting unless directed to do so by a medical professional.
It is also important to note that the Golden Chain Tree is toxic to pets. Dogs and cats that ingest any part of the tree may experience symptoms such as vomiting, diarrhea, and seizures. Therefore, it is recommended to keep pets away from the tree and to seek veterinary attention if you suspect your pet has ingested any part of the tree.
In conclusion, while the Golden Chain Tree is a beautiful addition to any garden, it is essential to be aware of its toxicity and take the necessary precautions to keep yourself and your pets safe.
