Golden yellow flower spikes. The flowers are a shade darker than the similar-looking Ribbed Melilot whose flowers are lemon yellow. The winged petals are similar in length to the inner petals, or keel. In Ribbed Melilot the keels are shorter. The flowers of Tall Melilot are more dense than those of Ribbed Melilot.
Fruit:
Black ridged pods. Despite all of the differences mentioned on this page between the two species, the differences are very subtle and the only sure way to distinguish between them is by the colour of their seed pods. The seed pods of Ribbed Melilot are browner than those of Tall Melilot.
Leaves:
Trefoil leaves with forward pointing toothed leaflets. The stalk of the central leaflet is slightly longer than the stalks of the two outer leaflets. Melilots are biennial plants.

Smells of hay when dry due to a chemical called coumarin. This is the substance responsible for the toxicity of the plant.

Summary

Melilotus altissima, also known as tall sweetclover, is a species of annual or biennial plant in the Fabaceae family. It is native to Europe and Asia and typically found growing in disturbed areas such as roadsides and waste places. The plants can grow to a height of 2-3m (6-10ft) and produce clusters of small white or yellow flowers. The leaves are divided into 3 leaflets and are hairy. Melilotus altissima is considered a weed in many areas and is not typically grown for any specific use. It does fix Nitrogen in the soil and could be used for green manure.

Tall Melilot, also known as Melilotus altissima, is a member of the legume family that is native to Eurasia but has spread throughout the world. This tall, herbaceous plant can grow up to 10 feet (3 meters) in height and is often found in fields, meadows, and along roadsides.

One of the most distinctive features of Tall Melilot is its fragrant flowers, which bloom in late summer and early fall. These small, yellow flowers grow in long, slender spikes and attract bees and other pollinators. In addition to its ornamental value, Tall Melilot is also an important food source for livestock and wildlife.

Tall Melilot has a long history of use in traditional medicine. Its leaves and flowers contain coumarin, a natural compound that has anti-inflammatory and pain-relieving properties. Coumarin is also a blood thinner, and some studies suggest that it may have anti-cancer properties as well.

In addition to its medicinal properties, Tall Melilot has also been used for various other purposes throughout history. Its flowers have been used to make perfumes and potpourri, and its leaves have been used to make tea. In some cultures, Tall Melilot is considered a sacred plant and is used in religious ceremonies.

Despite its many benefits, Tall Melilot can also be invasive in some areas. It spreads quickly and can outcompete native plants, which can have negative ecological impacts. For this reason, it is important to be aware of its potential for invasiveness and to take appropriate steps to control its spread.

Tall Melilot is a versatile plant that can grow in a variety of soil types and can tolerate both wet and dry conditions. It is a nitrogen-fixing plant, which means it has the ability to take nitrogen from the air and convert it into a form that can be used by plants. This makes it a valuable crop for farmers, as it can improve soil fertility and reduce the need for synthetic fertilizers.

Tall Melilot is also a valuable plant for honeybees, as its nectar is rich in sugars and its pollen is high in protein. Honey made from Tall Melilot nectar is light in color and has a mild flavor that is popular with consumers.

In some countries, Tall Melilot has been used to make biofuels. Its high biomass production and ability to grow in marginal soils make it an attractive crop for producing renewable energy.

Some Facts about Tall Melilot
