Lungwort (Pulmonaria) is a beautiful perennial that adds charm to shady gardens. For a fast-growing variety, Kelly Funk, president and CEO of Jackson & Perkins, recommends 'Raspberry Splash.' "This compact perennial features large green leaves splashed with silvery-white spots and raspberry-pink flowers in late spring to early summer," she says. "It delivers multi-season interest, showy blooms, bold foliage, and strong disease resistance." Plus, it is slug- and mildew-resistant and is a great companion to ferns and hostas.

  • Zones: 4 to 9
  • Size: 12 inches tall x 24 inches wide
  • Care requirements: Full shade to partial sun; well-draining soil

Inland sea oats (Chasmanthium latifolium) is a perennial grass with unique seed heads that resemble oats, bringing welcome texture to shade gardens. "The blue-green foliage emerges in spring and adds a nice color to the garden," says Damon Abdi, assistant professor of landscape horticulture at Louisiana State University AgCenter. This quick-growing grass reaches 2 feet tall by late spring. Abdi recommends cutting it back in late winter to allow for regrowth next season.

  • Zones: 5 to 9
  • Size: 2 to 4 feet tall x 1 to 3 feet wide 
  • Care requirements: Full shade to partial sun; moist soils

Elephant Ear

Elephant ear (Caladium) is identified by its heart-shaped leaves that appear in multiple shades, such as pinks, whites, and greens. "This plant grows from a tuber, which in warmer regions of the country, should be fine to overwinter in the landscape," says Abdi. "In colder areas, consider digging up the tubers and bringing them inside to avoid the worst of winter." He notes that this plant should reach maturity in one growing season.

  • Zones: 9 to 11
  • Size: 12 to 24 inches tall x 12 to 30 inches wide
  • Care requirements: Full shade to partial sun; well-draining soil

One of the most popular perennials in the garden, hostas are known for their striking foliage that give way to pink-purple flowers in spring. When this fast-growing plant outgrows its space it can easily be dug up and divided to add more plants to the landscape. "Keep this in mind when planting it as an understory specimen—it can be advantageous to plant just a few and then divide them every few years to fill out the area, rather than make an upfront investment," says Abdi.

  • Zones: 3 to 9
  • Size: 1 to 2 feet tall x 2 to 5 feet wide
  • Care requirements: Full shade to partial sun; well-draining, organic-rich soil

Begonias are extremely versatile, growing in various habits, from upright and mounding to trailing out of a container. "Their leaves are a work of art, so vibrant and asymmetrical," says Linda Vater of Southern Living Plant Collection. "Begonias come in a range of colors, from classic green to deep maroon, black, and even striking variegated patterns." She notes that nursery-grown begonias typically mature within one growing season.

  • Zones: 9 to 11
  • Size: 6 to 24 inches tall x 9 to 12 inches wide
  • Care requirements: Full shade to partial sun; well-draining, slightly acidic, lightweight soil

False forget-me-not (Brunnera macrophylla) is a hardy shade perennial that thrives in full shade. Funk recommends the 'Sea Heart' variety, which has bright blue spring flowers and heart-shaped silver leaves that last all season. "By mid-spring of the first year, the flowers are opening all over 'Sea Heart', facing straight up on slender stems carried above the foliage," she says. This plant flowers earlier than other Brunnera varieties, offering an extra week or two of beauty.

  • Zones: 4 to 8
  • Size: 12 inches tall x 24 inches wide
  • Care requirements: Full shade to partial sun; well-draining soil
