Leptotes (plant) are mounted on plaques of vegetal fiber or tree cork. Watering and fertilizer must be more frequent during active growth periods and less during dormant periods. Ideal growth conditions require an intermediate temperature and exposure to filtered sunlight.

A short time later, Mrs. Harrison sent a drawing and cutting of this plant to the botanist John Lindley, who verified

Females of many spider species, including "P. labiata", emit volatile pheromones into the air, and these generally attract males
