Inside-Out Flower

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.

Is inside-out flower a good choice for my yard?

Yes, if…

• You have shade. Oregon State rates it for part sun to full shade, and Portland Nursery says it’s ideal for dappled sun.
• Your soil is rich and stays a bit damp. The UW Botanic Gardens list humus rich, well-drained soil as its preference.
• You want a groundcover that fills in on its own. It spreads by underground rhizomes.
• You garden in the Pacific Northwest or Northern California. This is home ground for it, and it looks right with ferns and conifers.
• You like small things. The flowers are tiny. The reward is up close.

Skip it if…

• Your garden is sunny and hot. It wants afternoon shade at the very least.
• Your shade is dry and you won’t water. University of Arkansas Extension calls it the thirstiest of the three inside-out flowers; it requires more moist conditions than its cousins.
• You want green leaves all winter. Portland Nursery notes this species is deciduous; its evergreen relatives are listed in the cousins section below.
• You’re outside its range. It’s native to just three states on the Pacific coast, and it misses that cool, moist forest air elsewhere.
• You want a plant that shows from across the yard. This is a path-edge plant, not a showpiece.

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

• A shady slope under conifers, where lawn won’t grow.
• The edge of a woodland path, where you can bend down and see the flowers.
• The north side of the house, in the strip that never gets direct sun.
• Under deciduous trees, mixed with ferns and spring bloomers.
• A native shade garden as the low layer under shrubs.

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.

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.

• Inside-out flower (Vancouveria hexandra) is the white, deciduous one on this page, and the easiest to find.
• Redwood inside-out flower (Vancouveria planipetala) is evergreen, smaller and native from southwestern Oregon to mid-California. Portland Nursery calls it essentially a diminutive version of this one.
• Golden inside-out flower (Vancouveria chrysantha) is evergreen with yellow flowers, a little harder to grow and slower to spread.

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.

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!
