Highlights

Ignore the creepy name. Spiderwort is one of the most forgiving, cheerful natives you can grow. It shoots up in spring with grassy leaves and tall stems topped with clusters of blue-purple flowers that bloom for weeks!

Each flower lasts just a day, but new ones open daily, giving the plant a long flowering season from spring into early summer. Easy to grow in sun or part sun, clay or loam, dry or moist soils, spiderwort is the definition of beginner-friendly. Plant it where you’ll see it often, because the flowers are little daily surprises.

Spiderwort is one of those native plants you often see in landscaping and gardens, hiding in plain sight. Its shape looks so similar to that of other non-native plants like daffodils and bulbs that you might think it’s non-native. Surprise! Spiderwort has been growing in North America for thousands of years. In this article, we’ll explore its name, how to grow it, and introduce a few cultivar options.

Let’s start with a basic question:

Is spiderwort a good choice for my yard?

Yes, if…

Why spiderwort matters

It’s a pollinator buffet.

Spiderwort is a workhorse for pollinators, especially native bees. According to the Missouri Botanical Garden, the flowers are visited by bumble bees, sweat bees, syrphid flies, and butterflies throughout their long bloom period. The pollen is particularly interesting: spiderwort’s bright yellow stamens are covered in fuzzy hairs that attract bees. Some native bee species are especially drawn to these pollen-rich flowers, visiting them repeatedly throughout the morning hours when the flowers are open.

Spiderwort picks up where the first spring flowers and bulbs leave off, keeping the garden alive with color and the pollinators fed during a window when not much else is open.

It flowers during a gap.

Beyond pollinators, spiderwort matters because it fills a critical gap in the garden calendar. Most big native perennials (coneflowers, black-eyed Susans, asters, goldenrods) do not start blooming until June or later. Spiderwort picks up where the first spring flowers and bulbs leave off, keeping the garden alive with color and the pollinators fed during a window when not much else is open.

It is perfect for beginner gardeners.

It is also one of the toughest plants you can grow. The USDA Plant Guide for Virginia spiderwort notes that spiderwort thrives in a wide range of soils, from dry to moist and clay to loam. It handles full sun and part shade equally well. For beginning native gardeners who have been burned by fussy plants in the past, spiderwort is a confidence builder.

Native range

Sources: NatureServe, Royal Botanic Gardens, Kew (World Checklist of Vascular Plants) and the USDA PLANTS Database, compiled by The Plant Native. How we map native ranges

It depends on the species. At least 10 species of Tradescantia/spiderwort are native to North America. There are spiderworts native to just Texas, and other species native to the eastern half of the United States.

Ohio spiderwort (T. ohiensis) and Virginia spiderwort (T. virginiana) are the two you’ll most often find at nurseries, both with massive native ranges:

Ohio spiderwort

Tradescantia ohiensis

Ohio spiderwort is native to a vast part of North America, from Maine to Texas.

Virginia spiderwort

Tradescantia virginiana

Virginia spiderwort is also native to a large part of North America, from Maine to Louisiana and California.

Now you’re probably wondering—which one should I plant? Does it matter?

The two species look nearly identical in a garden setting. Both have grassy leaves, both grow 1 to 3 feet tall, and both have blue-purple flowers that bloom from late spring into early summer.

The best way to pick between them is not to stress about it. Buy whichever species is grown closest to you. The more local the source, the better the plant is adapted to your soils, weather, and pollinators.

Plant ‘provenance’ is a secret advantage for gardens

As you can imagine, a Virginia spiderwort with a family tree from New Hampshire will have much different DNA than a spiderwort from Georgia. The area where a plant’s DNA originates is called its provenance. Provenance takes hundreds or thousands of years to establish. Multiple generations of a plant must grow, cross-pollinate, and evolve for the DNA to build resilience and knowledge of its home area.

To briefly sum up plant provenance:

Plant nerd fact

Why is it called spiderwort?

The “spider” part comes from what happens when the stem is cut. According to the Missouri Botanical Garden, a “viscous stem secretion is released which becomes threadlike and silky upon hardening (like a spider’s web).”

It’s named for something that no one even sees—unless the plant is cut open.

Thanks for nothing, whoever came up with this sad common name! We’ve added spiderwort to our round-up of Beautiful Native Plants with Terrible Common Names. Let’s change this plant’s common name to cobalt fireworks in our lifetimes.

How to plant spiderwort

Full sun to part shade. According to NC State Extension, spiderwort grows well in full sun but also performs in part shade. Sunnier spots mean more flowers and more pollinators; shadier spots mean the plants stay a bit more compact and the flowers last longer into the afternoon.

When to plant

Transplants go in spring or fall. Seeds can be sown directly outdoors in fall (the cold winter helps break dormancy) or started indoors in late winter. Transplants from a native plant nursery will give you flowers the first year.

Spacing

Give each plant about 1 to 1.5 feet of room. Plant in groups of at least 3 for the best visual effect. Spiderwort looks best in clusters rather than single plants scattered around.

Planting card

Tradescantia ohiensis, T. virginiana

Watering

Water regularly during the first growing season while roots get established. After that, spiderwort is drought-hardy in most conditions. It prefers average to moist soil but handles dry spells without complaint.

Fertilizer

None needed. Rich soil can actually make spiderwort floppy. Average garden soil is perfect.

The mid-season cut-back

This is the one spiderwort trick every gardener should know. When the first round of flowers finishes (usually by mid-July), cut the entire plant back to about 6 inches above the ground. It sounds dramatic, but the Missouri Botanical Garden recommends this approach. Fresh, tidy growth will return within weeks, and you will often get a second round of flowers in late summer or early fall.

What are good pairings for spiderwort?

Pair spiderwort with native flowers that bloom at other parts of the season, like native penstemons and fall-blooming asters.

Where can I buy spiderwort?

Most big-box garden centers don’t carry true natives, but spiderwort is easier to find than you might think. Your best bets are a native plant nursery near you, a native plant society sale, or a trusted online grower that ships to your region.

FAQs

Does spiderwort spread?

Yes, slowly, by stolons (underground runners) and self-seeding. It is not aggressive, but a single plant will gradually form a wider clump over several years.

To keep them from spreading, dig them up, divide the plant (give the extra plant bits to neighbors and friends!), and replant the smaller pieces.

Is spiderwort invasive?

The two spiderworts sold as natives, Ohio spiderwort (Tradescantia ohiensis) and Virginia spiderwort (T. virginiana), are not invasive.

They spread by seed and offshoots, so a clump gets bigger over the years, and a spade handles the extras. Watch for non-native relatives though, like small-leaf spiderwort (T. fluminensis), a South American plant that smothers other ground covers

When does spiderwort bloom, and for how long?

Spiderwort blooms from late spring into early summer, roughly late May to early July. Each flower only lasts a day, but a fresh batch opens every morning and the show runs for weeks. Cut the clump back after the first round and you may get a second flush in late summer.

Can I grow spiderwort in a pot?

Yes! Use a container at least 12 inches wide with drainage holes. Spiderwort will bloom well in a pot, though you may need to water more frequently than you would in the ground. Bring the pot to a sheltered spot (like an unheated garage) over winter in cold climates.

Does spiderwort like sun or shade?

Spiderwort does best in full sun to part shade. It will grow in full shade, but you get fewer flowers. Give it a break from the afternoon sun, which is about when the flowers close anyway.

Why do the flowers close in the afternoon?

Each spiderwort flower is a one-day bloom. It opens in the morning and melts away by early afternoon, especially on hot days. A fresh set of flowers opens the next morning. To enjoy them at their best, visit your spiderwort patch in the morning.

When can I transplant spiderwort?

Move or divide spiderwort in early spring or fall. Trim the leaves back first, then keep the pieces moist and out of harsh sun until they settle in. A clump that has outgrown its spot easily splits into free plants.

Spiderwort is one of the easiest native plants you can grow. Let’s put this dreadful common name aside and plant this native flower in our gardens. Pair it with flowers that bloom throughout the rest of the summer into fall so that your garden looks amazing and pollinators always have something to snack on. Since spiderwort is so forgiving of soils—clay, loam—and sunshine—full sun, part sun—it is a perfect native flower for beginner gardeners. Want more fuss-free recommendations?
