On gardenworld.app you can have a garden design created in which this pleasantly growing plant plays a supporting role in diverse, dynamic borders. The plant spreads slowly via root tubers and forms a decorative group after a few years. With minimal care and no pruning requirements, this plant grows for years without maintenance.

Appearance & Bloom Cycle

The Astragalus glycyphyllos is a graceful plant with very long, feathery leaves that can reach up to 20 centimeters long. The leaves are green, compound, and give the plant a very refined appearance. The flowers appear in May to July in dense, clear clusters at the ends of the stems. The individual flowers are pearly white to very pale yellow and have the characteristic pea flower shape. After blooming, inconspicuous seed pods form. This is a low-growing plant that forms spreading mats and is very suitable for borders. The plant overwinters in mild climates without protection.

Ideal Location

The Liquorice milk-vetch thrives best in half shade to dappled shade. Full sun can cause scorched leaves in very warm climates, so protect against midday heat. A spot under low-hanging branches or against a north wall is ideal. The plant also grows well in shade, although blooming may be less complete. In its natural habitat, the plant grows on woodland edges and in open forests where it receives filtered light.

Soil Requirements

The Liquorice milk-vetch is not very demanding and grows well in most soils. A well-draining soil with some organic matter is ideal. The plant tolerates acidic to neutral pH (5.5-7.5) well. Heavy clay is less ideal but not deadly. Add some compost when planting and the plant will grow well. Once established, the plant requires no further fertilization.

Watering

The Liquorice milk-vetch needs regular moisture during the growing season, especially if it's dry. Water when the top layer of soil feels dry. Once established, the plant can tolerate some drought thanks to its strong roots. In rainy regions, extra watering is usually not needed. The plant also grows well in normal garden conditions without special moisture management.

Pruning & Maintenance

The Liquorice milk-vetch requires no regular pruning. After blooming, faded flowers can be removed to look neater, but this is optional. In spring, dead or damaged tips can be gently removed. The plant can grow for years without any pruning. No further maintenance is needed. Once established, this plant grows for years without maintenance.

Maintenance Calendar

• March-April: New foliage appears, water regularly
• May-July: Full bloom, white flowers very striking
• July-August: Bloom ends, seed formation
• September-October: Plant still grows, but growth slows
• November-February: Winter dormancy in mild climates, minimal water

Winter Hardiness

The Liquorice milk-vetch is hardy to USDA zone 6 (down to -23°C) in sheltered situations. In cooler climates (zone 5 and colder), the plant may be more vulnerable to long frost periods. Extra mulching with leaves or compost in very cold winters helps. In warm climates, the plant can even grow throughout winter. Testing in your specific region is recommended.

Companion Plants

The Liquorice milk-vetch combines beautifully with other woodland edge and half-shade plants:

• Ferns: For greenery and texture
• Helleborus: For early blooms
• Ajuga: For low green carpet
• Liriope: For structure and September blooms
