Ferns are some of the easiest shade perennials to grow. These deer-resistant plants grow best in rich, loamy soil with good drainage and in partial to full shade. Avoid planting ferns where they receive direct afternoon sunlight. Many fern varieties are native to the United States and grow best in zones 3-8. Available in a wide range of sizes, ferns add texture and color to gardens and are ideal for planting in woodland areas, shade gardens and containers. When buying ferns for sale online, take into account their mature height and spread. Also consider how you would like to use them. Some fern fronds are excellent for use in cut-flower arrangements.
