Ferns are some of the oldest living plants, growing in a wide range of cold, temperate, and tropical climates around the world. There are at least 12,000 species, from miniature to towering tree forms. These ancient plants, which evolved before flowering plants, reproduce from leaf spores rather than seed.

There are many fern types that can thrive in your landscape. Most ferns prefer shady, moist conditions and are low maintenance, with few pests or diseases. Ferns pair well with many other shade plants, as a serene green backdrop or taking center stage. Here are some of the best outdoor ferns to grow, along with outdoor growing tips.

CINNAMON FERN (Osmundastrum cinnamomeum)

Zones: 3-9
Habit: Upright vase-shaped habit
Height/Spread: 2 to 3 feet tall and wide

WESTERN SWORD FERN (Polystichum munitum)

Zones: 5-9
Habit: Mounding arching habit

Exposure: Partial to full shade

Native to western North America, this fern is characterized by long, lance-shaped foliage with deeply dissected leaves. Plants are evergreen or semi-evergreen, with dense clumps of fronds emerging from a crown of scaly rhizomes. Grow underneath shade trees or naturalize in a woodland garden. Adaptable to different soils and is somewhat drought tolerant.

GROWING FERNS OUTDOORS

There are many fern varieties available to home gardeners that are suited to outdoor conditions. Some tender ferns can be overwintered indoors as a houseplant in colder climates. When given the right conditions, ferns are easy to grow. Needs vary depending on the variety, so research individual ferns to make sure you are giving them the best care. Here are some basic growing tips:

Light: Choose a partially shaded site such as underneath a tree or on the north or east side of a home. Some ferns prefer more light, while others can tolerate more shade. Full sun may cause leaf scorch.

Soil: Provide well-draining soil that is amended with compost or other rich organic matter. Most ferns prefer a slightly acidic pH. For containers, use a high-quality, all-purpose potting mix and make sure pots have adequate drainage holes.

Water: Ferns prefer moist soil, though not soggy. Allow soil to dry out slightly in between waterings. Containers dry out more quickly, so will need more frequent water.

Fertilize: Ferns need little or no supplemental fertilizer. In early spring, mulch around the base of plants with a thin layer of compost, pine bark, or pine needles.

Pests and diseases: When grown outdoors, ferns experience few pests or diseases. Inspect plants on occasion and treat symptoms accordingly. (See more on garden pests and diseases.)

WHAT ABOUT ASPARAGUS FERN?

While not a true fern, asparagus fern (Asparagus spp.) is grown for its feathery green leaves that create an airy effect. This tender herbaceous perennial can be grown outdoors year-round in frost-free zones, treated as an annual in colder zones, or grown as a houseplant. Display in a hanging basket or container.

Zones: 9-11
Habit: Upright bushy habit
Height/Spread: 1 to 3 feet tall, 1-1/2 to 4 feet wide
Exposure: Partial sun outdoors, bright indirect light indoors

Note: There are several species of asparagus fern, with some listed as highly invasive in many areas when grown outdoors. Check locally to see if this is an issue where you are.
