Comestibilité

• The highly aromatic young leaves are used as a flavouring in salads and cooked foods [183].
• The young leaves are used to make a herbal tea [183].

Culture

• Prefers a warm sunny sheltered position and a well-drained soil .
• Réussi dans la plupart des sols .
• Although given a hardiness rating of 9 in [200] (which means that a plant is not very frost-tolerant), this species is thriving in a sunny bed at Kew Botanical Gardens and so should be hardy to at least zone 7 [K].
• Another report says that it withstands temperatures down to about -40°c when dormant .
• Yet another report says that it should succeed outdoors in the milder and drier counties, but that it is not very long-lived [233].
• The flowers are very attractive to bees .

Propagation

• Graines - semez au printemps sous serre et recouvrez à peine les graines .
• The seed usually germinates in 1 - 3 months at 13°c [133].
• Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year .
• Plantez les à la fin du printemps ou au début de l'été [K].
• Division au printemps .
• Fairly simple, if large divisions are used it is possible to plant them straight out into their permanent positions .
• Basal cuttings of young shoots in spring [111].
• Harvest the young shoots when they are about 10 - 15cm tall and pot them up in a lightly shaded position in a greenhouse .
• They should root within 3 weeks and can be planted out in the summer or following spring .
