How to plant tulbaghias

Tulbaghias fragrans or sweet garlics are eye-catching plants native to South Africa producing clusters of sweetly scented star-shaped flowers and lance-shaped leaves on wiry stems. Fantastic for the front of the border or rockery, these drought-resistant perennials can also be grown in containers — place near a door or window where their honey fragance can be appreciated in the night air.

Plant around 5 cm deep in well-drained, moderately fertile, humus rich soil in full sun. In frost-prone areas, provide a deep layer of mulch over the winter months. Allow several years before dividing clumps in spring.

Always unpack on arrival and store in a cool place until ready to plant.

Potential problems, pests and diseases:

• Aphids: these sap-eating insects can weaken plants and spread viruses. Whenever possible, pick off by hand using gloves.
