Are there any course in any flower shop and hardware store, a maximum of a few cents more expensive. Either way. I love nasturtiums in its heyday and taste. The seeds are well risen and the plants after flowering throw again as many seeds from that for years no new purchase is necessary. The leaves I take particularly like on bread, sometimes pure, sometimes with cheese. The flowers I eat less frequently, but also taste very good. The flowering period is also nice and long (May to August or so), so you have long some of it aesthetically.
