Description: Nasturtiums are vigorous and can grow as either vinelike or compact bushy plants. The leaves are nearly round, and the flowers are bright oranges and yellows with long spurs behind them.

How to grow: Nasturtiums need full sun in a dry, sandy, well-drained soil. They're at their best in regions with cool, dry summers, though they will grow elsewhere, too. Bushy types get viny or stringy if they have too little sun. Sow seeds outdoors in the ground after the last frost. Depending on variety, space them 8 to 12 inches apart.

Propagation: Sow seeds where they will grow; germination takes 7 to 12 days at 65 degrees Fahrenheit. Do not cover the seeds; they need light to germinate.

Uses: Dwarf varieties are good for flower borders, beds and edging paths, and walks. Vining varieties can be tied to fences or posts and trailed from window boxes and hanging baskets.

Related varieties: Dwarf Double Jewel, in separate colors and a mix, has light yellow, gold, orange, rose, and crimson flowers. Milkmaid is a fashionable shade of pale butter-yellow.

Scientific name: Tropaeolum majus
