In the Kitchen & Bar

  • Summer Drinks: Use the lilac pom-pom flowers as a stunning edible garnish for iced tea or botanical gin punch.
  • Desserts: The sharp, earthy menthol scent is the perfect culinary match for dark chocolate or rich berry compotes.

Expert Care Tips:

Watermint is a thirsty plant! If you aren’t planting it directly into a pond or bog, keep its pot in a deep saucer of water during the summer months to ensure the leaves stay juicy and the scent remains powerful. To maintain its shape in smaller gardens, simply divide and thin the roots in Spring or Autumn.

"I have purchased herbs from Kitchen Garden Plant centre and the quality of the plants are unparalleled. Such a fantastic selection to choose from and all grown on their family nursery from scratch. Packaging is great and the advice and guidance offered by this knowledgable team is simply the best. 10/10 would recommend and would only by my plants from this lovely team."

"These lovely folk had the unusual rosemary we had been searching for in lovely growth and good price. Feel more than confident to mail order from them in future too. Also, their Rau Ram (vietnamese coriander) has lovely subtle flavour that we'd never tried before ."
