Highlights

Inside-out flower (Vancouveria hexandra) looks like every bloom got caught in a gust of wind. Its six small white petals sweep sharply backward, with tips that Jepson eFlora describes as strongly reflexed, so each flower dangles like a tiny umbrella flipped the wrong way. Dozens hang together in loose sprays above a low, airy mat of leaves that Benton Soil and Water Conservation District calls duck-foot shaped.

It’s a forest-floor plant from the cool, shady woods of Washington, Oregon and California, where it can carpet the ground under Douglas-firs. Give it moist shade and a little patience, and it spreads into a soft green groundcover that blooms from May into early summer.

Why inside-out flower matters

In the Northwest’s older forests, this is one of the plants holding the ground together. A UW Botanic Gardens data sheet calls it a dominant understory perennial ground cover in late successional Douglas-fir forest, and a 2017 UW propagation protocol notes it grows in old-growth and coniferous forests. Planting it in a shady yard puts back a piece of that forest floor.

Its flowers aren’t just for looking at. Benton Soil and Water Conservation District lists it as a plant that draws insects, bees and butterflies, and it fills a niche few garden plants do: steady green cover in deep shade, where lawn gives up and bare soil washes away.

It’s also a good stand-in for a plant you may already know. Inside-out flower is a close relative of the epimediums (barrenworts) sold at many garden centers, and Oregon State even lists American barrenwort among its common names. If you want that same airy, shade-loving look with a plant that belongs in the West, this is it.

Where inside-out flower shines in your yard

Beginner tip

Buy three small pots instead of one big one. Plant them a foot apart, let them knit together, then divide the clumps in early spring to fill the next patch for free.

How to grow inside-out flower

When to plant

Set out nursery plants in spring. If a friend has a patch, the UW data sheet suggests dividing it in early spring. Seed is possible but slow: sow it fresh, and a UW protocol found seedlings begin germinating the March after they are planted.

Light

Part shade to full shade. Dappled light under tall trees is ideal, and the north or east side of a house works well. Keep it out of hot afternoon sun.

Soil and water

Rich, loose, slightly acidic soil is best, the kind that builds up under trees when you leave the fallen leaves in place. Oregon State calls for acidic, humus-rich soil.

Sources disagree on how thirsty it is, so plan for the wetter answer. The UW data sheet says it requires consistently moist soil and needs extra water for at least its first season. Portland Nursery calls it an excellent plant for dry, shady areas once it’s settled, and adds that keeping it on the dry side slows its spread. Water it through the first summer, then watch it. If the leaves stay fresh through August, you can ease off.

Size and spacing

Expect a mound about eight to sixteen inches tall, with flower stems reaching as high as 10-20 inches in bloom. For a carpet sooner, set small plants about a foot apart in a group rather than dotting them around the bed.

Pests

Portland Nursery calls it virtually pest and disease free. In the UK, the Royal Horticultural Society notes that vine weevil can be a problem, so check the roots of any potted plant before you buy.

Where is inside-out flower native?

Native to 3 US states

Native range
Not native

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

In the wild it grows from the south end of Puget Sound, west of the Cascades, down into northwestern California. Jepson eFlora places it in conifer forest below 1900 m, which is about 6,200 feet.

What are good pairings for inside-out flower?

Pair it with other natives that like cool, moist shade: western sword fern, western wild ginger, trilliums, bleeding heart and bunchberry. Above it, vine maple or salal make a natural forest edge.

Where can I buy inside-out flower?

Native nurseries in the Pacific Northwest and Northern California carry it. Portland Nursery in Oregon includes all three inside-out flowers in its native plant library, and native plant society sales in Oregon and Washington are another good bet. Make sure the tag says Vancouveria hexandra if you want this one. Start with our list of native plant nurseries or order online.

Inside-out flower and its cousins

There are three inside-out flowers, all from the Pacific coast, and they get mixed up in nurseries.

Then there are the epimediums. The easy way to tell them apart is to count: University of Arkansas Extension notes that epimedium flowers are built in fours and inside-out flowers in sixes. Beth Chatto’s nursery adds that inside-out flowers hold their blooms on taller stems than their cousins.

The reward is up close.

FAQs

Why is it called inside-out flower?

Because the petals bend backward instead of opening forward. One Pacific Northwest field guide describes them as bent backward, flared out, so the flower looks turned inside out. Oregon State compares the look to a shooting star.

Is inside-out flower evergreen?

Mostly no. Oregon State calls it deciduous to nearly evergreen, and in most gardens the leaves die back in winter. If you need winter green, look at redwood or golden inside-out flower instead.

Will inside-out flower take over my garden?

It spreads, and how fast depends on water. The UW describes slowly creeping rhizomes, while the Lady Bird Johnson Wildflower Center calls it a vigorous ground cover. In moist, rich soil it moves along; in drier shade it slows down. It’s easy to dig out at the edges.

Can inside-out flower grow in dry shade?

Sometimes, once it’s established. Portland Nursery grows it in dry shade, but Arkansas Extension rates this species as the one that needs the most moisture. Water it well for the first season and see how it does before you count on it.

How tall does inside-out flower get?

About a foot. The Lady Bird Johnson Wildflower Center gives up to about 1 foot tall, and flower stems can stand a little higher than the leaves.

Can I grow inside-out flower outside the Pacific Northwest?

Possibly, in cool, moist shade. Oregon State says it’s hardy to USDA Zone 6, and Arkansas Extension says the group is winter-hardy from zones 5 through 8. Summer heat and dry air are the bigger risks than cold.

Plant nerd fact

Wasps on seed duty

Inside-out flower gets help spreading its seeds from two unlikely partners. A 2017 UW propagation protocol notes it is associated with ants and yellow jacket wasps, which carry the seeds off.

The genus name has a seafaring backstory too. Vancouveria honors Captain George Vancouver, the British explorer of the Pacific Northwest.

Inside-out flower is a small plant with a big job: covering shady ground with something that belongs there. Tuck it under trees with a few ferns, keep it moist the first summer, and come May, get down on your knees and look. For more shade plants, see our guide to native ferns. Happy planting!
