Hosta ‘St. Elmo’s Fire’ features buttery-yellow new leaves which contrast with red stems and older green leaves with creamy margins. Displays light lavender flowers on tall scapes. Hostas grow best in moist, well-drained, highly organic soils. A good partner for ferns. Although the flowers are attractive, Hostas, also called Plantain Lilies, are usually grown for their ornamental foliage.
