Queen of the Prairie Companion Plants
Perennial Salvia
There are hundreds of different types of salvias, commonly called sage, but they all tend to share beautiful, tall flower spikes and attractive, often gray-green leaves. Countless sages (including the herb used in cooking) are available to decorate ornamental gardens, and new selections appear annually. They are valued for their long season of bloom—right up until frost. Not hardy in cold climates, they are easy to grow as annuals. Dense or loose spires of tubular flowers in bright blues, violets, yellow, pinks, and red form on square stems clothed with often-aromatic leaves. Provide full sun or very light shade in well-drained average soil.
Lobelia
Colorful lobelias are a wonderful choice for landscaping around ponds and streams—anywhere the soil is consistently moist. In fact, lobelia loves downright wet conditions, making it a top choice for bog gardens. Perennial types of lobelia (not to be confused with the low-growing, often blue annual types) attract hummingbirds, so they’re great for wildlife gardens. The foliage is a rich green to sometimes dark reddish-purple. The plant produces striking spikes of flowers in all shades of red, pink, blue, and white. Lobelia needs humus-rich soil. Mulch with a biodegradable material, such as wood bark or chopped leaves, to add humus to the soil.
