Nasturtiums are edible flowers with a peppery taste, like watercress.
Sow the seeds directly outside in the spring after all danger of frost is past. Choose a location with full sun or partial shade. Do not add fertilizer to the soil; nasturtiums do not need fertile soil. Water your nasturtiums sparingly.
Nasturtiums do well in a container or in the garden. They attract aphids, so plant them away from your brassica plants (broccoli, cauliflower, etc.) and they will help keep the aphids away from your vegetables.
