The summer Grandma Rosa moved in with us, she brought a cactus that bloomed only at night.
I didn't believe her at first. A flower that bloomed in the dark seemed like something from a story. But she set it on the back porch and said to check it after midnight, and I did.
The bloom was white and enormous — bigger than my hand — and it smelled like something between honey and rain. By morning, it had closed.
"Why does it do that?" I asked.
"Night-blooming cereus," she said. "It blooms for one night a year. The moths that pollinate it only fly at night."
I thought about that — a flower that had organized its entire existence around a single night, a single visitor. It seemed like a waste. What was the point of blooming if no one could see you?
"People see it," Grandma Rosa said, as if she had heard me. "We saw it."
I was quiet for a moment. The cactus sat there looking ordinary in the morning light, nothing about it suggesting what it had been twelve hours before.
"It's still beautiful," I said, "even if it's only for one night."
"Especially because of that," she said.
I didn't fully understand until the following July, when she wasn't there to watch it bloom with me.
But I watched it alone, and it was still exactly what she said it was.
