Known for their violet, blue, or pink blossoms and grass-like foliage, Spiderworts are dependable, easy-to-grow, and surprisingly long-lived. Their flowers attract bees, butterflies, and even hummingbirds while thriving in sun or partial shade.

From the golden-leaved Sweet Kate Spiderwort to the richly hued Amethyst Kiss and Concord Grape, these perennials add texture, color, and natural movement to the garden. If you're looking for an adaptable perennial that performs beautifully with little fuss, Spiderworts are a must-have.

A Botanical & Historical Look

Native to North America and belonging to the Commelinaceae family, Spiderworts have enchanted gardeners and herbalists for centuries. The genus name Tradescantia honors English naturalists John Tradescant the Elder and his son, who introduced many New World plants to Europe in the 1600s.

Their common name, "Widow's Tears", reflects the plant's tendency to exude a clear, sticky sap when the stems are broken - droplets that resemble tears in the sunlight. In folklore, Spiderworts were thought to bring good fortune and were once used in herbal remedies for minor wounds and inflammation.

Each Spiderwort features slender, arching leaves that resemble ornamental grasses, forming elegant mounds of green or gold foliage. The three-petaled flowers - typically about an inch across - sit atop slender stems in airy clusters. Blooms emerge in early summer, with each lasting just one day, but the plant produces so many buds that it remains in bloom for weeks or months.

Root systems are fibrous and moderately shallow, making Spiderworts excellent for stabilizing slopes or adding color to rain gardens.

Landscaping Uses

Spiderworts are natural multitaskers in the landscape. Their soft, flowing habit and vivid blooms make them a beautiful choice for cottage gardens, perennial borders, and woodland settings. They're perfect companions for Ferns, Hostas, Astilbes, Daylilies, and Catmint, as well as shade-loving annuals like Impatiens or Sunpatiens.

Use Sweet Kate Spiderwort's bright golden foliage as a luminous contrast to deep purples or dark greens. Concord Grape and Amethyst Kiss varieties shine in mass plantings or naturalized sweeps, where their blue-violet blooms catch the morning sun. For a native touch, Ohio Spiderwort (Tradescantia ohiensis) blends beautifully into prairie plantings and pollinator gardens, pairing well with Tall Ornamental Grasses, Rudbeckia, and Coneflowers.

Spiderworts also thrive near ponds or streams, softening the edges with their arching foliage and colorful accents - a peaceful addition to a meditation garden.

Planting & Growing Tips

Light: Spiderworts thrive in full sun to partial shade. In hotter regions, afternoon shade helps preserve bloom color and prevent foliage scorch.
Soil: Prefers moist, well-drained soil, slightly acidic soil, but adapts easily to most garden soils, including clay and sandy loam.
Spacing: Plant 12-18 inches apart to allow good air circulation.
Water: Keep soil evenly moist, especially during the first growing season. Once established, Spiderworts are moderately drought-tolerant but bloom best with consistent moisture. For guidance, try the simple Finger Test before watering.
Companions: Excellent alongside perennial grasses, shrub roses, and Hydrangea bushes for layered color and texture.

Plant Spiderworts in spring or early fall to give roots time to settle before temperature extremes. A proper mulch layer helps retain soil moisture and keep roots cool.

Care & Maintenance

Spiderworts are refreshingly easy to care for, requiring little more than routine grooming to look their best.

Deadheading: Trim back spent blooms to encourage fresh flowers and keep plants tidy.
Pruning: After the main flowering flush, cut back the foliage by one-third to promote dense regrowth and possibly a lighter late-summer rebloom.
Fertilizing: Feed in early spring with a balanced, slow-release fertilizer for perennials or compost.
Watering: Maintain moderate watering during dry spells, following watering tips for healthy growth.
Winter care: In colder zones, allow the foliage to die back naturally and mulch lightly over the root zone.

Division & Propagation

Spiderworts can form large clumps over time, so division every 3-4 years helps rejuvenate them and prevent crowding.

To divide:

Dig up the clump in early spring or fall.
Gently separate the roots into sections, ensuring each has several shoots.
Replant divisions promptly and water well.

This not only keeps your Spiderworts healthy but also provides new plants to share or expand your garden's tapestry.

Frequently Asked Questions

What conditions do Spiderworts grow best in?

Spiderworts prefer moist, well-drained soil and thrive in full sun to partial shade. They tolerate clay and are adaptable in many garden settings.

Do Spiderworts bloom all summer?

Each flower lasts one day, but the plant produces blooms for several weeks or months from late spring through mid-summer, with a possible rebloom after pruning.

Are Spiderworts invasive?

Some species can self-seed or spread through rhizomes. Regular division and trimming help keep them contained.

Do Spiderworts attract pollinators?

Yes, bees, butterflies, and even hummingbirds visit Spiderwort blooms for nectar and pollen.

Can Spiderworts grow in containers?

Yes, compact varieties like Amethyst Kiss™ perform beautifully in pots and mixed container gardens with annual flowers and perennial grasses.

How do you propagate Spiderworts from stem cuttings?

Take 4-6 inch stem cuttings from healthy Spiderwort plants in late spring or early summer when growth is most vigorous. Remove the lower leaves and place cuttings in a glass of water or directly into moist potting soil. Roots typically develop within 2-3 weeks in water or 3-4 weeks in soil. Plant rooted cuttings outdoors after the last frost date in zones 4-9, spacing them 12-18 inches apart.

When is the best time to plant Spiderworts in the garden?

The best time to plant spiderworts is in early spring after the last frost date or in fall, 6-8 weeks before the first expected frost in zones 4-9. Spring planting allows the roots to establish during the growing season, while fall planting takes advantage of cooler temperatures and autumn moisture. Space plants 12-18 inches apart in partial shade to full sun locations with well-draining soil. Plant at the same depth as the nursery container and water thoroughly after planting to ensure good root-to-soil contact.

What USDA hardiness zones are suitable for growing Spiderworts?

Spiderworts thrive in USDA hardiness zones 4 through 9, making them suitable for most temperate regions across the United States. These hardy perennials can tolerate winter temperatures down to -30°F in zone 4 and perform well in the heat and humidity of zone 9. In zones 4-5, plant them in spring after the last frost date, while gardeners in zones 6-9 can plant in either spring or fall. Choose a location with morning sun and afternoon shade for best performance in warmer zones.

How often should you water Spiderwort plants?

Spiderworts prefer consistent moisture and should be watered deeply once or twice per week, providing about 1 inch of water total. During hot summer months in zones 7-9, increase watering frequency to every 2-3 days, while cooler northern zones may need watering only once weekly. Allow soil to dry slightly between waterings to prevent root rot, but never let plants become completely drought-stressed. Check soil moisture by inserting your finger 2 inches deep - water when the top inch feels dry.

How do you prune Spiderworts to encourage bushier growth?

To encourage bushier growth in spiderworts, pinch back the growing tips when plants reach 6-8 inches tall in late spring. You can also cut back the entire plant by one-third to one-half after the first flush of blooms fades in midsummer. This technique works well in zones 4-9 and prevents the plant from becoming leggy while promoting a second wave of flowers. Make clean cuts just above a leaf node or side shoot to encourage new branching.
