To create a visually appealing garden, combine flowers that start with A with different heights, bloom times, and colors. For example, plant tall Alliums behind colorful Asters, border pathways with fragrant Alyssum, and add vibrant Azaleas for seasonal impact. Mixing annuals and perennials ensures year-round interest while layering plants adds depth and texture. Including pollinator-friendly varieties also creates a lively, eco-friendly garden filled with bees, butterflies, and beautiful blooms.
