Chinese ground orchids growing in a terrarium. I grow this same color ground orchid, both outdoors in the ground, and in a wide pot, to bring inside to enjoy half the year. I have never thought of growing them in a terrarium.
Hoya is a super sweet vine plant with thick green and white leaves. If you keep it in medium or high light and water and drain it every two weeks, it'll bloom with little clusters of very fragrant, star-shaped flowers.
