While most annual plants for Nebraska landscapes are grown for their flowers, some can be grown for their foliage, fruit and trailing growth habit. Like the annuals grown for their colorful flowers, these other annuals can be used in beds, borders, rock gardens, window boxes, hanging baskets and containers. Annuals used for their foliage contribute texture, form, size and mass characteristics to the overall effect.

Herbs such as basil, sage and fennel are often used in landscape designs for their foliage and fragrance rather than their flowers. Ornamental grasses and grass-like plants such as ornamental corn, millet and sedge can be planted as annuals. Grasses are usually planted as perennials but several annual grasses are available for Nebraska landscapes. Vegetables, such as peppers, make excellent landscape annuals. Additional maintenance on this group of annuals may be required, such as occasional trimming and harvesting fruit. Irrigation and fertilization requirements for annual plants, especially during initial establishment, should also be considered in light of maintenance commitments.

When designing with all annuals, consider site conditions and the preferred growing requirements. Evaluate the planting site’s sun exposure, wind patterns, water requirements, soil type and fertility, and then choose plants that will perform in these conditions.

The following list of plants contains suggestions for annuals that are often grown for landscape traits other than their flowers.
