Pests in Gardens and Landscapes

Nasturtium—Tropaeolum spp.
Family Tropaeolaceae (Nasturtium family)

Plant Identification

Nasturtiums are rapidly growing annual or perennial plants. Some species are compact and bushy while others climb or trail along the ground. Leaves are rounded or may be deeply lobed. Flower color varies and may be reddish-brown, orange, yellow, red, or white. Nasturtiums bloom in spring, throughout the summer, and well into fall. They attract butterflies.

Optimum conditions for growth

Nasturtiums prefer sandy soils, but will do well in most well-drained soil type. They do well in full sun or partial shade and require regular water. Some species can tolerate drought conditions.
