There are so many types of ornamental grass to choose from that you'll be spoiled for choice if you're looking for ways to keep borders looking good in autumn and winter. Once perennials finish flowering at the end of summer, flowerbeds can often feel empty and lack interest, but grasses will solve that problem with ease.
As well as being low-maintenance and reliable, grasses fill borders with grace and movement. They have flower panicles that billow on the breeze, and wonderful color once they take on their fall hues.
Designers use them to create a naturalistic look, reminiscent of a meadow, and to ensure the garden is impressive during winter. Along with the architectural seed heads of perennials such as globe thistle, grasses endure through the cold months, providing fawn and gold tints and are spellbinding when dusted with frost.
Key border grasses include feathery Miscanthus, bottlebrush-like Pennisetum, elegant Calamagrostis, and upright Panicum. All provide structure, lightness, and autumn color.
With so many benefits, it's certainly worth learning how to grow ornamental grasses. They work hard, performing in summer, autumn and winter alike, and create a beautiful naturalistic look.
