These plants are Neoregelia Bromeliads. In the wild, they grow in the trees of South American rainforests. Indoors, they make fine house plants.
Bromeliads are colorful for long periods of time. Their color comes from their rosette of leaves — not flowers. So they retain their color for many months.
I found a live Neoregelia Bromeliad “Skotak’s Pink Powder” for sale here.
