Where to plant:
Picking the right spot for your salvia can make a difference in how well the plant grows and flowers. Most salvias will be happiest in a sunny spot with good drainage. Use them along your home's foundation or as part of mixed perennial borders. They can also be grown in containers. Salvias are especially nice for growing along paths because of the way they spill over and soften the edges.
Salvia plants don't need rich soil, but they must have good drainage. If your soil is heavy, plant "proud", or slightly higher than the surrounding grade. In pots, a mixture of ordinary garden soil mixed with perlite allows water to drain rapidly. Whether in the garden or in a pot, a mulch of wood chips or small, rough-edged rock is highly recommended to not only protect the roots, but to help keep the soil temperature and moisture consistent.
Salvias don’t like to be crowded. When planting in groups or amongst other plants, determine the spacing based on their mature size. Space them far enough apart to ensure good air circulation.
