It is uncertain what is meant by a "group".
If you Google "youngest species" you find that polýploid hýbrid flowers are the newest and easiest to create, with Senecio eboracensis at 40 years ago. The cross sign × is supposed to be written before the specific epithet but isn't represented in the paper.

Angiosperms
flowering plants are part of a large group called angiosperms. They are the only (and most recently evolved group) to have flowers. Nonflowering plants are gymnosperms, seedless vascular plants (like ferns) and bryophytes.
Flowering plants, or angiosperms, are the most recently evolved and diverse group of plants. They first appeared around 140 million years ago and have since diversified into a wide range of species, making them the dominant group of plants on Earth today.

gametangia
flower. Flowers are the reproductive structures in angiosperms that have evolved relatively recently compared to other plant reproductive structures. They are specialized to attract pollinators and facilitate the process of pollination and fertilization.

The two kingdoms in Eukarya that evolved most recently are Animalia and Fungi. They emerged relatively later in the evolutionary timeline compared to other eukaryotic kingdoms such as Plantae and Protista, with Animalia diverging from a common ancestor with fungi around 1.2 billion years ago.
Bamboo wasn't invented it was a plant that evolved and grew naturally just like most of the other plants in the world.
