All you need to know about Nasturtium

Nasturtium belongs to the Tropaeolaceae family which includes about 80 species of annual and perennial herbaceous flowering plants that are native to South and Central America.

Annual Nasturtiums

  • Tropaeolum majus (Garden Nasturtium, Indian Cress) is a popular annual or short-lived perennial with creeping or sprawling stems that command attention in any landscape. It boasts a profusion of long-stalked, funnel-shaped flowers, about 2-3 in. wide (5-7 cm), in a wide range of hot colors. The blossoms have an unusual and refreshing fragrance and are edible. They stand out against the pretty foliage of rounded, parasol-like leaves.
     
  • Tropaeolum minus (Dwarf Nasturtium) is a bushy, compact, low-growing annual with rounded, shield-shaped leaves and rich orange or reddish-orange flowers, sometimes with purple veins or with red blotches. Dwarf Nasturtium is a mini version of Garden Nasturtium and is a better choice for small gardens.
     
  • These easy-to-grow, warm-season annual plants are perennial in hardiness zones 9-11.

Perennial Nasturtiums

  • Tropaeolum peregrinum (Canary Creeper) is a frost-tender perennial climber that boasts a profusion of spurred, bright yellow flowers from summer until the first frosts. Reminiscent of the wings of canaries, they contrast nicely against the foliage of pale blue-green, deeply five-lobed leaves. Canary Creeper is hardy to zones 10-11 and grown as an annual in cool areas.
     
  • Tropaeolum speciosum (Flame Nasturtium) is a slender herbaceous climber with a profusion of brilliant, long-spurred, scarlet flowers from summer to fall. Creating a spectacular floral display for months, they contrast nicely against the foliage of dainty, deep green, clover-like leaves. In the fall, the fiery blossoms are followed by a striking display of sapphire-blue berries held in red sepals. Flame Nasturtium is hardy to zones 8-11. It adds a tropical touch to gardens with cool, moist summers.
     
  • Tropaeolum tricolor (Tricolor Nasturtium) is a summer-dormant, tuberous, perennial climber with a profusion of tricolor flowers from winter to early summer. They create a spectacular floral display for months and contrast nicely against the soft, bright green, deeply lobed leaves. Tricolor Nasturtium is hardy to zones 8-10. It is one of the longest flowering species of Tropaeolum. It is mostly cultivated as an ornamental.
