Spiderwort might sound like something from a horror movie, but this attractive plant is far from frightful. The origin of its odd name is unclear. Some say the three-petaled blooms resemble a spider, while others believe it was named for its use by indigenous people to treat spider bites (though this is not recommended today). Another theory links the name to the viscous fluid it produces, which hardens into a thread-like web.
Regardless of its name’s origins, spiderwort is a beautiful plant that brings many benefits to your garden, enhancing its beauty and attracting wildlife.

Native to North and South America, Tradescantia includes about 85 species, and varieties like prairie, western, Ohio, and Virginia spiderwort are common in areas like Minnesota and the eastern United States.
This herbaceous perennial is incredibly easy to grow and maintain, thriving in moist, well-drained soil with full sun or part shade. Naturally pest and disease-free, it’s a low-maintenance choice for gardens. In spring, you can propagate spiderwort with at least 10 inches of space between plants to allow room for its self-seeding habit. To manage this, you can hear it in mid-season.
The spiderwort flowers only last a day, but the plant continuously produces blooms from spring through summer in shades of purple, blue, red, and white. Different colours may blend over time when planted in proximity, so consider grouping them in separate areas for a striking display. Pairing spiderwort with wonderful companion plants can further enhance your garden.
Ideal for a naturalistic prairie landscape or a pollinator oasis, companions include little bluestem, butterfly weed, whorled milkweed, sky blue aster, coreopsis, round-headed bush clover, rough blazing star, prickly pear cactus, black oak, wild bergamot, and prairie phlox.
When the spiderwort flower starts to flop and look unattractive, a quick clip will rejuvenate it, allowing neighbouring plants to shine. Whether used as a feature in a pollinator garden or as part of a diverse prairie landscape, spiderwort is a versatile, hardy plant that adds charm and vibrancy to any garden.

Growing Spiderwort Flower
Spiderworts are easy-to-grow plants known for their resilient nature and ability to thrive in various conditions. These hardy plants are well-suited to USDA plant hardiness zones 4-9. And can tolerate moist, well-drained soil with an acidic pH of 5 to 6. Whether your garden is in partial shade or sunny, spiderworts adapt as long as the soil is moist. Their forgiving nature makes them ideal for gardeners looking for low-maintenance yet beautiful flowers.
To start growing spiderworts, you can use purchased plants or propagate them through division, cuttings, or seeds. Plant the plants in spring, placing them 4 to 6 inches (10–15 cm) deep and spacing them 8 to 12 inches (20.5–30.5 cm) apart. For propagation, stem cuttings taken in summer or fall root easily in soil, while seeds can be sown outdoors early and lightly covered with soil. If seeds start indoors, plant them about eight weeks before transplanting outside.
With minimal effort, spiderworts reward gardeners with vibrant blooms and a robust growing habit. Their ability to establish strong roots quickly makes them a reliable addition to any garden. And their adaptability ensures success for novice and experienced gardeners.
Care for Spiderworts
Light Requirements
Spiderwort flowers are versatile and not overly picky about sunlight. They grow well in partial shade but adapt to environments with a few hours of light daily. Choose a sunnier spot to encourage vibrant blooms and a more showy plant. If the plant receives all-day sunlight, ensure it gets adequate water to stay healthy.
Soil Conditions
Spiderworts thrive in moist, well-draining soil that is slightly acidic with a pH of 6.8 to 7.2. While they can adapt to various soil conditions, they perform best in nutrient-rich, humusy soil. Plant them in spring at a depth of 4 to 6 inches, leaving at least a foot or more between plants to allow their clumps and sprawling nature to flourish with enough room.
Water Needs
Though spiderworts are drought-tolerant, they prefer consistently moist soil. Water them every few days, particularly during the hot summer months. In areas with regular summer storms, natural rain is often sufficient to keep the plants happy and blooming.
Temperature and Humidity
Spiderworts are hardy and not fussy about temperature or humidity. They are well-suited for various hardiness zones and thrive from early spring to late summer. Their ability to adapt to different climates makes them a reliable choice for many gardens.
Fertilizer Application
A single application of fertilizer in early spring is generally enough for outdoor spiderwort plants. Follow the product label instructions for the proper amount and enhance the soil with compost for added nutrients. This care supports robust growth and promotes steady blooming through the growing season.
Pruning for Maintenance
After the bloom period, spiderworts may look ragged. To refresh the plant, shear one-third of the 8-12 inch stems or remove old leaves to encourage new growth and extend late-season blooms. Regular pruning also helps prevent self-sowing and keeps the plant from becoming weedy. Mid-season secretions resembling spider webs give the plant its common name, adding to its charm while requiring simple upkeep to maintain a tidy appearance.
Final Observations
Spiderwort flower is a delightful addition to any garden, combining low-maintenance care with vibrant and long-lasting blooms. Their adaptability to different conditions, from sunny spots to partial shade, and their ability to thrive in various soil types make them an excellent choice for gardeners of all experience levels. Whether aiming to create a pollinator-friendly space or simply wanting a pop of colour in your landscape, spiderwort delivers charm, resilience, and beauty all season long.
