Idea Garden:

Propagation:   Nasturtiums are easy to grow from seed.  Seeds can be sown directly in the garden beginning in May, or started indoors around mid-April. Cover seeds as they require darkness to germinate.  Seeds will germinate in 7 to 14 days at 60 to 65 F.    Transplants can be set out after Mother’s Day.  However, as nasturtiums do not fare well when transplanted, use peat pots and plant these directly in the soil.


Nasturtium is both a beautiful garden annual and a useful culinary herb.

Nasturtiums are easy to grow, with flowers in various colors, mainly red, orange or yellow, all summer.  They’re great as a groundcover, in large containers, hanging baskets, or trailing out of raised beds and down slopes.  The abundant, colorful blooms can be cut for use as an elegant entree garnish or salad decoration. The leaves, which contain a good dose of vitamin C, can be used to add a peppery flavor to fresh salads. It is this flavor, similar to that of cress, from which the common name comes, meaning “nose twister” in Latin.

Nasturtiums are also planted as a companion plant in the vegetable garden to ward off pests.  The following is a list of benefits when interplanted with nasturtium:

  • cabbage family  – deter cabbage caterpillars and whiteflies
  • cucumbers – fewer whiteflies and cucumber beetles
  • runner beans –  keep aphids off
  • tomatoes and potatoes – keep aphids & whiteflies off
  • squash – deter squash beetles and borers

In addition to deterring unwanted insects, they are useful in attracting beneficial predatory insects to your garden.
