There will be a glow of color over the Boothbay peninsula from just before Thanksgiving to New Year’s Eve, illuminating trees and rocks and gardens — a heaven of lights cascading over the Boothbay Botanical Gardens.

Gardens Aglow is the first-ever epic lighting of the beautiful landscape at the Botanical Gardens, as staff there, all 20-plus, have been working since September on this collaborative art project.

The stringing of 150,000 LED lights through the trees and bridges over 14 acres of the 270-acre garden spread is no small feat. Gardeners and workmen pooled their creative energy for several months making the Gardens Aglow come to life. And, there’s no peeking!

Gates will open Nov. 21 and remain open through Dec. 31, Thursday through Sunday, from 4 to 8 p.m. The Gardens will be closed Thanksgiving Day and Christmas Eve.

Tickets are available online at Mainegardens.org, or at the door. A special bonus for the hungry: The Kitchen Garden Cafe at the Botanical Gardens will be offering dinner on those nights the Gardens Aglow are alive, with turkey and prime rib on the menu. Outside, a s’more pit will be burning and there will be gourmet hot chocolate.

“The goal is to create an opportunity for visitors to come to the peninsula during the off-season,” said Kris Folsom, marketing director at the Gardens. Area stores, lodging and restaurants are enthusiastic about the prospects of keeping the Route 27 peninsula down to Boothbay Harbor hopping through the end of the year.

“Join us this winter for the biggest light display this side of the Piscataqua River as we light up the night here at Coastal Maine Botanical Gardens,” the Gardens said, at the nonprofit’s website.

The Gardens Aglow takes place in the more accessible upper gardens, which are easier to walk around in. There will also be complimentary wheelchairs, as well as scooters for rent, weather permitting.

The lights are all LED, with a variety of colors. Some even change color on their own.

“The electrical usage is equivalent to light an average two-bedroom Maine house,” said Folsom. “It is extremely efficient lighting.”

Late in the fall, in the still-warm November weather, staff was moving around, digging holes and wrapping lights, joking as they worked into the afternoon. But, they were unanimously adamant that no one but staff would get a preview of the Gardens Aglow until the official opening.

“Wait for the magic,” they laughed.
