DH has demonstrated this numerous times. She's fond of taking cuttings from plants (mostly flowering) that catches her fancy in gardens of places we visit. And I would jokingly threaten her to stop or else I call the guard in the premises.
When we went on a road trip this summer for Visita Iglesia, we had lunch in a place called Cafe Casa Rap in San Jose Batangas. In that place's garden, most of us in the road trip were simply awed by these flowers.
Here's a picture of the flower from Wikipedia. I later found that this plant is called "Thunbergia Mysorensis" although it's also known as "Clock Vine", "Ladies Slippers", "Doll Shoes" and "Brick and Butter" Vine.
