Nasturtium is an annual flowering plant in the genus Tropaeolum, native to South and Central America. The plant is a vining herbaceous perennial with bright, orange, yellow, or red flowers. The leaves are edible and have a peppery flavor. The flowers are also edible, and can be used to give salads and other dishes a peppery flavor. The plant grows best in full sun and rich, well-drained soil. Nasturtium is a good choice for container gardening, as it can easily be trained to climb along fences or trellises. The plant is also attractive to bees, butterflies, and other beneficial insects.

Planning Your Garden With Nasturtiums

As you plan your garden, it's important to think about the spacing, size, light, and nutrient requirements of all of your plant and how they'll grow together.

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.

By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.
