Uses of Nasturtiums (and Nasturtium Caper Recipe) and Seeds To Sow Now

  • 5 min read

The end of Spring is a great time for sowing a huge range of seeds. Scroll down to see a guide of Seeds to Sow Now, but first we'd love to tell you about something a bit different you can do in your garden at this time of year.

The Many Uses of Nasturtiums

Nasturtiums are a surprisingly beneficial plant to have in your garden. Not only do their bright flowers lighten a space, but they also attract pollinators and beneficial insects, provide ground cover and prevent invasive weeds from taking over. They prefer poor soil so are easy to grow and are very easy to pull out if you decide you want the space for something else. They are a great companion to most plants in your garden.

Were you aware that nasturtiums are also edible? You can eat every part of the plant; from it's leaves which can be chopped into salads, to the gorgeous edible flowers. What we'd love to show you in this article is how you can turn nasturtium seeds into capers!

Picking nasturtium seed pods for capers Picking nasturtium seed pods for capers

Nasturtium seed pods develop at the end of the plant's season: right about now at the end of Spring. The flowers start to die off and leave in their place three little green pods that, when pickled, look and taste surprisingly like capers! You can easily pick lots of these little pods and turn them into an inexpensive and delicious food. 

Get out there and make the most of your handy nasturtiums! Be sure to leave some of the pods to dry out and self-seed for next season.


Nasturtium Caper Recipe

This recipe has come from our friends at Pip Permaculture Magazine. You can see their full blog here.

To make one small jar of nasturtium capers you will need:

  • 1/2 cup green nasturtium seeds
  • 2 tsp salt
  • 2 cups water
  • 2 tsp sugar
  • 3/4 cup white vinegar


  1. Rinse the nasturtium seeds and place them in a jar.
  2. Make a brine solution with 1 cup of water and 1 tsp salt and pour this over the seeds. Place the lid on the jar and let it sit at room temperature for 24 hours.
  3. Drain and rinse the seeds and repeat step 2, letting them sit for another 24 hours in brine.
  4. Drain and rise the seeds well and place them in a sterilized jar.
  5. Mix together the vinegar and sugar in a saucepan and bring them to the boil. Pour this liquid over the nasturtium seeds, ensuring they are all covered, and allow to cool. You may wish to add spices and herbs to the vinegar solution such as peppercorns, bay leaves, thyme or whatever takes your fancy.
  6. Once cooled to room temperature, place the lid on the jar and your capers are ready! Refrigerate after opening and they will store in the fridge for at least 6 months.

Use these nasturtium capers just as you would traditional capers, adding a tangy burst of flavour to any dish. Enjoy!
