Spring in Door County
On this Wisconsin peninsula, a vast array of wildflowers rewards those weary of winter.

A pink lady's slipper is one of the many orchids that grow at Ridges Sanctuary.
Goldthread and gaywings. Bogbean and trailing arbutus. In Wisconsin's Door County, it's enough to make a naturalist hyperventilate.
Cherry blossoms and daffodils are the showiest spring flowers on this tourist playground between Lake Michigan and Green Bay. But it's the wildflowers, many of them rare, that provide the most joyous proof that spring has arrived.
On sandy ridges, the first flower spotted often is the once-common trailing arbutus, whose waxy white blossoms emerge in April.
"It's the first big sign of spring, and when it's in full bloom, it reminds me of Ivory dish soap," says naturalist Karen Newbern. "I usually find myself getting down on my knees and sticking my nose into them."
Every type of wildflower flourishes on this narrow peninsula, from the steep dolomite headlands along Green Bay to the bogs and beaches of Lake Michigan. But one spot is such a luxuriant showplace it's practically the Tiffany's of wildflowers.
Along Baileys Harbor, 25 species of orchids grow amid 30 sand ridges, pushed ashore in a ripple pattern over 1,200 years. Separated by wetland strips called swales, they're home to species rare in Wisconsin.
The threatened dwarf lake iris grows here by the thousands, along with Arctic primrose, cancer root and ram's head lady's slipper. Cool lake breezes give this patch of land the characteristics of boreal forest, normally found much farther north.
"It's also called taiga," Newbern says. "We've had people from Sweden here who recognized the plants, and naturalists from Russia — their language was limited, but they could throw around the Latin names, so we had a common language."
Habitat for more species of plants than any other place in the state, it nearly became a trailer park in 1937. Local citizens protested, and the original 40 acres became Ridges Sanctuary; since then, the preserve has grown to more than 1,400 acres.

During the Festival of Nature, a guest stoops to look at bog plants along a boardwalk.
It's a magnet for nature lovers in May, when it holds its three-day Festival of Nature, with naturalist-led field trips throughout the northern half of the county.
Looking for wildflowers
When I was there one year, I started out at the Ridges, with a walk led by Newbern and volunteer Cathie Mann.
From the visitors center, we walked down a boardwalk between two 1869 range lights that once allowed Lake Michigan sailors to get "on range" by lining up their fixed white and red beacons.
On the marshy land below, we could see the tiny lake iris, with yellow-and-white tongues amid purple petals. Today, they grow only in Michigan and three counties of Wisconsin.
"Because they like the shoreline, they've really suffered from development," Newbern said.
Across from the lower range light, at the edge of the beach, we found a cluster of wildflowers that included arctic primrose, Indian paintbrush, bastard toadflax and starry Solomon's plume. They were all on the petite side.
"If you ate nothing but sand, you'd be skinny, too," Mann said.
Life isn't easy for the plant life. On the beach, Newbern pointed out phragmites, a fast-spreading reed that chokes every native plant in its path.
"Picture crabgrass on steroids," she said. "That's what this stuff is; I kid you not."
From the beach, we walked along Sandy Trail lined with gaywings, whose bright-magenta sepals turn out like the wings of an airplane.
On Sandy Swale, Newbern pointed out bog rosemary and the red-veined leaves of a pitcher plant, which digests insects that crawl into its pitcher-shaped leaves and drown in the water that collects there.

In late spring, gaywings bloom along the trails of Ridges Sanctuary.
On the Wintergreen Trail, we found a tiny goldthread and the leaves of the ram's head lady's slipper, the sanctuary's rarest and most elusive flower. It blooms in early June with the more-abundant pink moccasin and yellow lady's slippers.
Beside a boardwalk over Cowslip Swale, we saw a stand of bogbean, also called buckbean, whose star-shaped flowers were filled with crinkly, glowing white hairs.
We were nearly back to the visitors center when Newbern stooped to point out the asparagus-like stem of the striped coralroot, a cold-loving pinkish orchid that contains no chlorophyll or green leaves.
"That's why I like going with these naturalists; otherwise, I'd walk right by," said Teri Rycyzyn of Tinley Park, Ill. "It's wonderful, all these people willing to share what they know."
A walk through the trees
In the afternoon, I joined Mike Schneider's trees and shrubs walk on the other side of the peninsula, on the exposed western edge of the Niagara Escarpment.
Door Bluff Headlands Park, Schneider said, owes its untouched state to Jens Jensen, the landscape architect who, in 1935, founded the Clearing, the folk school Schneider now directs.
"Jens was on the five-man advisory board that had to decide what to do with it, and he said, 'Do nothing — keep it, and some day people will appreciate having it,'" Schneider said.
Clinging to dolomite cliffs high above Green Bay, gnarled white cedars were hundreds of years old but still no bigger than a bodybuilder's bicep. Schneider calls them "amazing survivors."

The dwarf lake iris is endangered, but it grows by the hundreds in Door County's Ridges Sanctuary.
"This has to be one of the most difficult environments in North America," he said. "There's hardly any soil, hardly any nutrients, and it's prone to deep freezes and drying winter winds."
Early French explorers called the trees arbor vitae, he said, because there's enough vitamin C in their leaves to cure scurvy.
We passed a wild black cherry, known as the potato-chip tree for its flaky bark; a white ash, used for baseball bats; and basswood, favored by decoy carvers. Schneider knew them all.
"I'm a tree fanatic," he said.
Cruise to Rock Island
Spring arrives first on the Green Bay side of Door County, surrounded by shallower waters that warm up faster. On the cooler Lake Michigan side, trees leaf out and wildflowers bloom one week or even two weeks later.

A 1927 stone boathouse greets visitors to Rock Island.
"It's great," says Paul Regnier, former Ridges Sanctuary director. "If you're on the bay side, you can say, 'OK, these are gone, let's go to the lake side and see them there.' "
At Rock Island State Park, completely surrounded by water at the far tip of the peninsula, spring comes later still. Regnier led a Festival of Nature field trip to the island.
As we walked through maple-beech forest to the 1858 Pottawatomie Light, he told us why its uncluttered floor made it easy for him to spot wild leeks and the odd spring ephemeral.
"Alien worms brought in by the fishing industry are eating all the leaf matter," Regnier said. "They advance right through and eat things up. You take that away, and the whole forest changes."
On the sunnier parts of the island, however, Indian paintbrush flourished, carpeting the sandy paths leading to the beach.
The biggest splashes appear in May: scarlet paintbrush, bright white trillium and the shiny yellow lady's slipper, official wildflower of Door County.

Boat captains used these range lights to help them enter Baileys Harbor.
"After living in this gray-green landscape, to get these bright colors, it's good for the soul," Regnier says.
All flowers are welcome in spring. But if you go to Door County in late May or June, try to find the little ones you may not see anywhere else.
"You have to make that annual pilgrimage down to your knees," Cathie Mann says.
Anyone can spot a daffodil. In Door County, you can spot just about anything.
