People sometimes referred to Penumbra as a “hidden gem,” according to its co-owner, Alison Murphy. Just a block away from Main Street, the plant shop may have been hiding in plain sight.

Murphy is confident moving her store that one block will make all the difference.

The plant shop opened its doors at its new location on Wednesday, the former Main Street storefront of Indigo Blues, welcoming shoppers into a bright space where leaves, flowers and fronds spilled over the edges of display tables.

“People would refer to us as a hidden gem, which we really love being, but we’re also ready to share what we do with more people,” said Murphy, who owns the store alongside her wife, Alyssa McClary. “That’s what it feels like Main Street is going to do.”

Who Doesn’t Want That, a local gift shop and consignment store, moved to South Main Street a few months ago. At its former Warren Street address, the store was just steps away from Penumbra. The neighboring shops’ moves demonstrate the appeal of downtown’s central artery to small businesses, even to those already downtown.

“I’ve always loved Main Street since I was a kid, since I used to go into all the different shops that were downtown with all the creaky floors,” said owner Polly Boghosian. “Downtown is where everybody is. Where everybody helps each other.”

She’s already woven into the community, recently collaborating with CandleTree Soy Candles.

Boghosian isn’t just happy with the address; she also adores the “nice big open space,” which allows her to host in-store workshops and other programs.

“If I had to say what kind of store I wanted and what it would look like,” she said, “this would be it, for sure.”

Penumbra’s new space is a little more “cozy” than the old one, Murphy said, but its open layout is a plus: “the easier to fill with plants, the better.”

Murphy opened the new storefront to the public just days after she had received the keys — but as the former owner and operator of Concord Handmade, a seasonal pop-up market, she said she’s familiar with a tight turnaround.

“I am so used to getting a space in early November and turning it into a store by mid-November,” Murphy said. “We know how to move everything in and turn tables into beautiful displays and have everything set up, so it doesn’t feel like a daunting timeline for me.”

Murphy anticipates that Main’s status as a “much more hopping place” with high foot traffic will bring more shoppers into the store.

At Who Doesn’t Want That, Boghosian is already seeing that play out. She said business has been “absolutely” booming since making her move.

She also feels like she’s more in the loop.

“I feel like I know all the gossip now,” she said. “Off Main Street, you’re kind of like, ‘What’s going on down there?’ It’s like you’re a kid looking in the candy shop.”

Now, she’s finally made it into that shop.

“I just love it,” Boghosian said.
