This went in a completely different direction than I originally planned.
Location/Situation: Fresh Picked Flowers
Oliver learned early on in his relationship with Felicity that she had a green thumb. Apparently it wasn't only people she charmed, she could charm almost anything. Before they'd moved in together he knew that she liked flowers- there was always a new vase of fresh picked flowers around. They were diverse too. Sometimes she'd have big bouquets of daisies and other times there were bouquets of mixed flowers, somehow combining all these together beautifully. There had been a night that he'd finally asked a question about it.
"Do you buy a new bouquet every week?" He had been sitting at her island, watching her cook (she'd refused his help), and every once in a while staring at the flowers.
"What?" She looked up and he gestured to the vase on her table. "Oh. No I never buy flowers. I have a plot at a community garden."
"Really?" He was impressed, it was something new.
When they moved in together he'd made sure to get a little house that had room for a garden in the back, as a surprise so she wouldn't have to go to the community garden- well if she wanted of course. It didn't take long for her to set up a garden that covered a large amount of the yard. For the most part it was the spring where she saw flowers, but there were even some that bloomed in the fall and winter.
He liked it, so when she spread out just a little he didn't mind. Eventually there were multiple vases in their house, a couple in their lair, and one on her desk and on the conference table at Queen Consolidated. After a year or two, the backyard was like a meadow of wildflowers; Felicity spent a lot of time out there, so that was where he was too.
It was in this meadow that they'd have date nights in the summer, where he had proposed to her, where they got the flowers for her wedding bouquet, and where she'd told him that she was pregnant.
The meadow had become such a pinnacle of their relationship that when their twins were born they added on to the house instead of moving. The garden grew over the years as well, since it seemed that both of the twins had green thumbs too.
And finally, when they both died, decades later, their children buried them out in the flowers, planting specific flowers by the graves.
Years earlier Felicity had taught both of them about the different meanings that people associated with each species. So, they decided on a sunflower, an aster, and a protea king. The sunflower, which they'd been taught symbolized adoration, dedication, and a dedicated love, they planted behind the headstone. The aster was for Felicity, it meant patience, courage, elegance, and daintiness, something Oliver had always said was the embodiment of Felicity. Lastly, there was a protea king in front of his side of the headstone. It meant change and transformation, daring and resourcefulness, which was probably the best way to sum up Oliver.
The flowers grew well, seemingly like Felicity's green thumb was still at work even after death, showing that there might be life after death after all.
