Eve

A ghostly pale shrub from a derelict lost in the void beyond the rents; it grows without water, and roots in anything - quite literally, as the roots can dig through soil, potting ceramic, and even the metal of bulkheads with equal ease. You have to keep it suspended in a hanging planter to be sure it doesn't cause a hull breach. It only flowers for a single day each year, but the delicate blue-white flowers and the scent they produce are worth the trouble of keeping it trimmed back the rest of the time.
