Tropaeolum majus. Salad Blend nasturtium seeds are part of the Whirlybird series. These Nasturtiums hold their edible flowers high above the foliage. Salad Blend nasturtiums feature spurless, half-double flowers in tangerine, soft salmon, deep gold, deep mahogany, bright scarlet, cream and cherry-rose. Pick and wash a handful of these bright summer flowers and just tear them into pieces over a summer salad. The result transforms a simple salad into a work of art. Nasturtiums are very easy to grow, and quite drought tolerant, so they are a fine choice for xeriscaping. In the right environment nasturtiums will self sow and come back year after year.
