What Is the Spiderwort Plant?
Spiderwort refers to a group of perennial plants in the genus *Tradescantia*, named after 17th-century English botanist John Tradescant. There are over 75 species, but some of the most popular include *Tradescantia zebrina* (often called wandering Jew), *Tradescantia pallida* (purple heart), and *Tradescantia virginiana*, the classic garden spiderwort.
Despite the name, spiderwort has nothing to do with spiders. The name likely comes from the plant’s sap, which was once used to treat spider bites—or perhaps from the way the stems branch out like spider legs. Whatever the origin, the name adds a touch of mystery to an already intriguing plant.
Appearance and Growth Habits
Spiderwort plants are known for their slender, arching stems and lance-shaped leaves that grow in a spiral pattern. The leaves can be green, purple, or variegated with silver or pink stripes, depending on the variety. The real showstoppers, though, are the flowers.
Each bloom typically has three petals and comes in shades of blue, purple, pink, or white. They open in the morning and close by the afternoon, often lasting just one day—but don’t worry, new buds appear daily during the blooming season. This gives the plant a continuous floral display from late spring through summer.
Benefits of Growing Spiderwort
Beyond its visual appeal, spiderwort offers several practical benefits that make it a smart choice for gardeners and indoor plant lovers alike.
Air-Purifying Abilities
Like many houseplants, spiderwort helps improve indoor air quality. Studies, including those by NASA, have shown that certain *Tradescantia* species can remove pollutants such as formaldehyde, xylene, and toluene from the air. This makes it a great addition to homes, offices, or any indoor space where air quality is a concern.

Attracts Pollinators
If you’re looking to support bees and butterflies in your garden, spiderwort is an excellent choice. Its nectar-rich flowers are a favorite among pollinators, especially in early summer when food sources may be limited. Planting spiderwort alongside other pollinator-friendly species like bee balm or butterfly plant can create a vibrant, eco-friendly garden space.
Edible and Medicinal Uses
Surprisingly, some parts of the spiderwort plant are edible. The young leaves and flowers can be added to salads for a mild, slightly peppery flavor. Historically, Native American tribes used spiderwort in poultices to reduce inflammation and treat skin irritations. While modern research is limited, the plant’s traditional use highlights its versatility beyond decoration.
How to Care for Spiderwort
One of the best things about spiderwort is how easy it is to care for. Whether you’re growing it indoors or outdoors, this plant is forgiving and adaptable.
Light Requirements
Spiderwort prefers bright, indirect light but can tolerate partial shade. Too much direct sunlight, especially in hot climates, may scorch the leaves. Indoors, place it near a window with filtered light. If you’re growing it as a houseplant, avoid dark corners—this plant needs some light to thrive.
Watering and Soil
Keep the soil lightly moist but not soggy. Overwatering can lead to root rot, so make sure your pot or garden bed has good drainage. Spiderwort isn’t picky about soil type—it grows well in average garden soil, sandy loam, or even rocky areas. For container growing, a well-draining potting mix works best.
Temperature and Humidity
This plant enjoys warm temperatures between 60°F and 80°F (15°C–27°C). It’s not frost-tolerant, so if you live in a colder climate, bring potted spiderwort indoors during winter. It adapts well to average household humidity, making it ideal for indoor growing.
Pruning and Propagation
Regular pruning helps keep spiderwort looking tidy and encourages bushier growth. Simply pinch back the tips of the stems or trim leggy sections. The best part? Spiderwort is super easy to propagate. Just snip a healthy stem, remove the lower leaves, and place it in water or moist soil. Roots usually develop within a week or two.
Growing Spiderwort Indoors vs. Outdoors
Spiderwort is versatile and can thrive in both settings, but there are a few things to consider.
Indoor Growing Tips
When grown indoors, spiderwort makes a lovely hanging plant or tabletop display. Its trailing stems look great in macramé hangers or elevated planters. Just remember to rotate the plant occasionally so all sides receive equal light. For added flair, pair it with other easy-care plants like the ZZ plant or polka dot plant.
Outdoor Landscaping Ideas
In the garden, spiderwort works well in borders, rock gardens, or as ground cover. It pairs beautifully with hostas, ferns, and other shade-loving perennials. Because it spreads easily, consider planting it in contained areas or using barriers to prevent it from taking over.
Common Problems and Solutions
While spiderwort is generally trouble-free, a few issues can arise.
Pests and Diseases
Aphids and spider mites may occasionally visit, especially in dry conditions. A gentle spray of water or insecticidal soap usually does the trick. Root rot is the most common issue, but it’s easily avoided with proper watering and drainage.
Leggy Growth
If your spiderwort starts looking sparse or stretched out, it’s likely not getting enough light. Move it to a brighter spot and trim back the long stems to encourage fuller growth.
Conclusion
The spiderwort plant is a true multitasker—beautiful, beneficial, and beginner-friendly. Whether you’re drawn to its colorful blooms, air-purifying powers, or ease of care, this plant deserves a spot in your home or garden. With minimal effort, you’ll enjoy weeks of vibrant flowers and lush foliage that brighten any space.
So why not give spiderwort a try? It’s a plant that proves you don’t need to be an expert to grow something amazing. Grab a cutting, plant it in a sunny spot, and watch it flourish. Your garden—and your lungs—will thank you.
