As for Plaza, she sought advice from her neighbor Dandelion -- who, according to the actress, is a witch.
"I went to Dandelion and I said, 'I'm getting married. Nobody knows. If you could do a spell or tell me if this is a good idea, anything, I'd really like some help,'" she shared. "She went, 'I have just the thing.' She went in her house, rummaged around, came out with a rosemary wreath that she gave me -- she literally cackled, gave it me."
With her wreath in hand, Plaza set out to create the ceremony space.
"I created a very quick love altar in my yard: facts of our love, little stones, smoke, fire, things of that nature," she explained. "And then the man from Alhambra showed up in a Hawaiian shirt with a briefcase and I can't remember a lot of it. It was fuzzy. But I'm pretty sure it's legal."
Forgoing a white dress and tuxedo, Plaza and Baena opted for different attire.
"Jeff got really into tie-dyeing during the quarantine," she said on a December 2021 episode of The Drew Barrymore Show. "So, I decided that Jeff and I were going to wear tie-dye pajamas that he had made for us."
As they embarked on their journey as newlyweds, Plaza and Baena navigated being both work and life partners.
"It's so great. It's so complicated," she told Drew Barrymore about the pair's collaboration on films and TV shows. "It's extreme highs and extreme complications. It's a really hard thing to navigate. But man, we've been together for 11 years. We just muscle our way through it."
And the Ingrid Goes North star acknowledged married life isn't always easy.
When asked how she related to her White Lotus character Harper in a November 2022 GQ profile, Plaza included in her answer, "I've been with my husband for 12 years. I relate to being in a relationship that has peaks and valleys, and going through a rough patch and comparing yourself to another couple that seems perfect."
But all the ups and downs with work and life made her think about what's really important.
"My partner's a filmmaker, and we've made movies together," she shared on a 2020 episode of HFPA In Conversation. "We've had really good experiences and really bad experiences, and I think I learned going through those things that ultimately movies come and go. Movies -- it's what are our lives are built off of. But when you're about to die, you don't think about the movies. You think about the people in our life and your relationships. I think that's what most people think about before they die."
