- Zone 3 - Full Sun, Part Sun - Bloom Season Summer to First Frost - Annual - Features Attracts Bees, Hummingbirds, Butterfly?s - Life Cycle Perennial, Annual - If you are looking for variety, you have come to the right flower. There are over 700 species of this plant that originated in warm and temperate climates. There are annual and perennial varieties aplenty. - Spiky flowers are borne on bushy plants. Sizes generally range from 10"" to 60"", with most varieties below 36"". You most likely know, and readily recognize, the bright red and scarlet Salvia. But, the flowers are also found in most colors, including blue. - Keep weeds under control during the salvia growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination. - Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant?s stems to prevent possible rot. - Careful watering is essential in getting salvia perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge. - Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important. - After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots. - ?Deadhead?, remove spent flower heads to encourage continuous flowering and prevent seed development. - Remove and discard foliage after a hard frost in fall. - In colder regions, apply another layer of mulch (1-2 inches) after the ground freezes in fall. Evergreen boughs (from Christmas trees) provide additional protection. Remove this mulch in the spring.
