How to Care for Spiderwort Plants


A mounded, bushy plant with long, lance-shaped leaves and bright purplish-blue bossoms, the spiderwort looks a little like fireworks bursting out in your summer garden. Grown as a native plant in many areas of the country, the spiderwort is an easy to care for perennial friend that will delight you with plenty of show all season long.

Step 1

Choose a location with full sun to part shade. Moist, well drained soil is preferred for spiderwort. Too much shade will result in a spindly, droopy plant. Full sun should prove the most conducive to flower production.

Step 2

Prepare the soil like any perennial bed. Add up to 4 inches of organic compost and till with the soil to a depth of one foot. This provides nutrients and allows the plant to successfully establish roots.

Step 3

Plant spiderworts 12 to 18 inches apart to allow for mature growth and air circulation. Cultivars may grow as tall as 2 feet, with shorter varieties at 12 inches in height.

Step 4

Water after planting. Spiderworts are perfect for the carefree gardener, as overly moist soil is tolerated as well as drought by these hardy perennials.

Step 5

Cut back foliage to soil level if it begins to look spent or go dormant. New growth and a possible second bloom cycle may be the reward. Cutting back spent blooms and seed pods will also prevent rapid spread of spiderworts through self seeding, a trait for which this perennial is infamous.
