Other notes: In cultivation, most varieties of nasturtiums prefer to be grown in direct or indirect sunlight, with a few preferring partial shade. The most common use of the nasturtium plant in cultivation is as an ornamental flower. It grows easily and prolifically, and is a self-seeding annual. They go from seed to bloom very quickly. Nasturtuims are great for beginners as they are easy to grow.

The peppery-tasting leaves are sometimes used in salads. The brilliant yellow, orange, or red flowers are funnel-shaped and have a long spur that contains sweet nectar.
