Melilotus indicus seed
LATIN NAME: MELILOTUS INDICUS
COMMON NAME: Indian Sweetclover, Annual Yellow Sweetclover
Indian sweetclover is one of those quiet plants that most people walk past without a second glance, yet it is quietly everywhere and quietly useful. It grows as a slender, upright annual or biennial, usually knee-high or a little more, with finely divided leaves in threes like a small clover, and slender spikes of pale yellow pea-flowers through the summer. The whole plant gives off a sweet, hay-like scent, especially as it dries, which is how it earned the name sweetclover, and it sways lightly in the breeze with a soft golden bloom. Native to southern Europe, the Mediterranean and western Asia, it has spread to warm and temperate regions around the world, and wherever it grows it is doing a quiet job, pulling nitrogen from the air through its roots and feeding it into the soil.
Scientific Research & Plant Biotechnology
Indian sweetclover has a firm place in agricultural and plant science. Like the other clovers and melilots, it is studied for its nitrogen-fixing partnership with Rhizobium bacteria, and it appears again and again in field trials on green manures and soil improvement, where its ability to add nitrogen and organic matter to poor ground is measured and valued. The plant also contains coumarin compounds, which give it that sweet scent, and these have been studied for their chemistry and for their effects on livestock, since related compounds have medicinal uses. In recent years sweetclover has also drawn attention in forage and bioenergy research as a low-input crop for marginal land. For a plant that grows wild along roadsides, it carries a surprisingly practical scientific record.
Ecological & Economic Value & Wide Applications
To grow the Indian Sweetclover from seed, ecologically, Indian sweetclover is a benefactor of the poor ground. It feeds nitrogen into the soil for the plants that follow, its flowers provide nectar for bees and other pollinators through the summer, and its quick, leafy growth covers disturbed soil. In farming it is grown as a forage and pasture plant, valued for feeding livestock and building soil, and it is a well-known honey plant that yields a fine, light honey; in the garden the young shoots can be used sparingly as a potherb. For a grower it is a cheap, dependable, hard-working crop that pays back in soil fertility, and for a land manager it is one of the most useful plants for bringing tired ground back to life. To raise Indian sweetclover, sow the small seeds where they are to flower, raking them lightly into moist soil in spring and keeping the ground gently watered until the little seedlings are up.

Indian sweetclover is a plant that most people walk past without noticing, which is a shame, because it is quietly everywhere and quietly useful. It grows as a slender, upright annual or biennial herb, usually knee-high or a little more, with finely divided leaves in threes, like a small clover, and small spikes of pale yellow pea-flowers in summer. The whole plant gives off a sweet, hay-like scent, especially as it dries, which is how it earned the name sweetclover. It is a light, airy plant that sways in the breeze and carries a soft golden bloom through the warm months.
It belongs to the pea family, Fabaceae, and it is native to southern Europe, the Mediterranean and western Asia, though it has now spread to warm and temperate regions around the world. Like its relatives, it is a nitrogen-fixer, pulling nitrogen from the air through nodules on its roots and feeding it into the soil, which is why farmers and land managers value it so highly.
Positive & Encouraging Seed Germination Guide
Indian sweetclover is one of the easiest seeds you will ever sow. The small, hard seeds germinate quickly and reliably in warm, moist soil, usually within one to two weeks. Sow them in spring, either scattered over a prepared bed or sown in rows, and rake them in lightly, since a little covering helps them hold moisture. They are tolerant of poor soil and dry conditions, so they will grow where many plants struggle. Once the seedlings are up they grow fast and will be flowering within a couple of months. It is a satisfying crop for a beginner, and it does a real job in the garden, improving the soil as it grows. Even a small sowing will fill a patch with green growth and pale yellow flowers, and if you let some seed ripen, the plant will often come back on its own.

Ecological & Economic Value & Wide Applications
Ecologically, Indian sweetclover is a benefactor. It feeds nitrogen into the soil, improving fertility for the plants that follow, and its flowers provide nectar for bees and other pollinators through the summer. It is widely used in green manures, cover-crop mixtures and land restoration, especially on disturbed or poor ground.
Its economic value is practical and varied. In farming, it is grown as a forage and pasture plant, valued for feeding livestock and building soil, and it is a well-known honey plant, producing a fine, light honey. In the garden, the young shoots can be used sparingly as a potherb, and the plant is sometimes grown for its sweet, hay-like fragrance. For a grower, it is a cheap, dependable, hard-working crop that pays back in soil fertility, and for a land manager it is one of the most useful plants for bringing tired ground back to life.
