The color of summer flowering bulbs will be enhanced when interplanted with summer flowering annuals such as petunias, marigolds and other annuals. Many of the summer bulbs are tall and the lower part of the plant unattractive after bloom. Plants like lilies and dahlias can be interplanted with perennials, annuals or shrubs to hide the lower stem area. Daylilies are a good choice to hide the lower stems of the lily. Color Considerations - Colors give us a feeling or perception of either warmth or coolness.
Cool colors are shades of blue, violet and green.
Warm colors are shades of red, yellow and orange. To the homeowners eye, warm colors are perceived as advancing while the cool colors seem to recede. Cool colored flowers will recede even more if they are placed in the shade. The perception created by warm or cool colors can be used by the homeowner in planning flower plantings in the landscape. When planted at a distance, warm colored flowers will appear closer while cool colored flowers will appear farther away.
