Patrick Dougherty's stick sculptures grace colonial Salem, Massachusetts

What it will be, nobody exactly knows: neither the 50 volunteers who will have happily trudged for hours through muddy woodlands north of Boston to gather tractor-trailer loads of saplings—linden, beech, Norwegian maple, depending on what the thaw has yielded—nor the artist himself, Patrick Dougherty. Only during the three weeks spent laying out those saplings, planting some, and then bending, twisting, and weaving them all together do the final, fantastical forms emerge. The work opens to the public on May 23. Dougherty, who hails from North Carolina and earned degrees in English and hospital administration before pursuing art, has erected more than 250 such sapling-based structures across the country and around the world during the last three decades. Judging from these, what ends up on the lawn of the colonial-era Crowninshield-Bentley House in Salem, Massachusetts, on May 23, might feature turrets or Russian onion domes, or look like a condensed Moroccan palace. It could resemble a softer, sway-backed version of Stonehenge, a clump of medieval thatched huts, or skinny teepees pushed askew by the wind. Dougherty’s constructions tend to have doors and windows, but they are not homes. “Seussical” is too whimsical a description; the dreamscapes are more suited to a van Gogh landscape, or even The Scream. What might add another twist in Salem is whether, and how, Dougherty juxtaposes his installation with the symmetrical, squared-off Georgian-style home and its formal front entrance. Built by fish merchant and sea captain John Crowninshield in 1727, the house is a historic site now owned by the Peabody Essex Museum, which commissioned Dougherty’s work. Whatever the resulting forms, they are expected to stay up for two years—unless nature reclaims them first.
