How to Grow and Care for Native Spiderwort (Tradescantia subaspera)

Spiderwort (Tradescantia subaspera) is a long‑lived native wildflower that brings soft color, graceful foliage, and dependable blooms to shady and woodland gardens. I’ve grown spiderwort for many years, both in my own yard and while tending gardens for a Master Gardener and Master Naturalist. My love for native plants began even earlier I learned to garden at a young age by helping my father in our family gardens. Those early lessons shaped everything I do today.

This guide will help you identify, grow, and care for spiderwort using real examples from my garden, with photos taken right here on my property.

🌱 What Spiderwort Looks Like

Tradescantia subaspera is a native woodland perennial that thrives in shade to part shade. Its dark green, arching leaves are long and slender, giving the plant a graceful, fountain‑like shape. When mature, spiderwort reaches 20–26 inches tall with a spread of about two feet.

Bud clusters form in April, followed by blooms in May, and the plant continues flowering into July.

🌸 Bloom Color and Flower Structure

Spiderwort produces delicate three‑petaled flowers in shades of white, rose, purple, and deep blue. Each bloom lasts only a day, but the plant produces so many buds that it flowers continuously for weeks.

🌿 Where to Grow Spiderwort

Spiderwort thrives in:

• Shady rock gardens
• Woodland edges
• Moist, rich soil
• Containers in part shade

I grow mine in the shady section of my rock garden and tucked among my hostas. It’s a forgiving plant that adapts well to clay soil, rocky terrain, and naturalized woodland settings.

🍃 Seasonal Care and Maintenance

After Blooming

Once the blooms are spent, cut the plant back. Spiderwort naturally goes dormant during the heat of summer.

Summer Protection

Apply a layer of leaf matter, pine needles, or wood‑chip mulch to help retain moisture and suppress weeds.

Fall Revival

In early September, remove the mulch and fertilize lightly. Spiderwort often rewards you with a second flush of fall blooms.
