Dichondra is an ornamental foliage plant favored for its fast growth in filling hanging baskets or sprawling as a groundcover. Its leaves are green or silver, depending on the cultivar, and the stems grow up to 4 feet long. The seeds germinate best in warm conditions. Chlorophytum, also known as spider plants, are great performers for hanging baskets. Tiny plantlets form on long, trailing stems, and white flowers produce seeds. Kudzu is an aggressive, weedy, trailing vine in the legume family. Long, fuzzy seedpods containing beanlike seeds follow purple flowers shaped like grape clusters.
Very fine seeds of trailing torenia and snapdragons need light to germinate. Lightly pressing these seeds on top of a growing medium and keeping them moist ensures germinating success. Snapdragon seeds also benefit from a cold treatment of sowing outside in late winter before the weather warms in spring. Petunia and portulaca plants are easy to grow from seeds and bloom with a profusion of flowers. Ivy geraniums are trailing plants with a different flower form from traditional garden geraniums, or pelargoniums. Seeds are available in a rainbow of flower colors.
Requiring excellent drainage for healthy growth, herbs are suited to container culture. Many are easy to grow from seeds, including oregano, thyme and mint. Most herbs enjoy full sun, although mint tolerates more shade. Trailing herbs, such as oregano and thyme, fill in as groundcovers around upright herbs, such as basil and chives, for a spaghetti herb garden. Trailing rosemary, sometimes called prostrate rosemary, has more of a horizontal growth pattern instead of the traditional, upright form.
A solution for backyard gardeners with limited gardening spaces is growing trailing tomatoes. One tomato vine fills a large, hanging basket or spills over a deck planter box. Descriptive names like Tumbling, Cascade, Patio and Pixie indicate smaller sizes and cascading habits for tomatoes. Seeds for trailing tomatoes are readily available at garden centers and from on-line seed catalogs. A sunny deck or patio can contain many hanging baskets of red and yellow tomatoes perfect for summer salads or for healthy snacking right off the vines.
