The Blue Plantain Lily is a large, naturally occurring hosta that is native to China and North Korea. It grows in a rounded mound to 22" tall spreading to 36" wide. Thin, smooth, shiny, cordate, broad-ovate, dark green leaves (9" by 8") have widely spaced veins, undulate margins and mucronate tips. Leaves develop strong ribbing as they mature. Bell-shaped, purple to violet flowers bloom in late summer to early autumn on upright, leafy, burgundy-spotted, pale green scapes (32-38"). Hostas are a mainstay of shade gardens. This large mounded hosta makes an interesting garden specimen. It is also effective in groups or massed. It can be mixed with other perennials in shady borders, shade gardens or woodland gardens. Easily grown in average, medium moisture, well-drained soils in part shade to full shade. Tolerates full sun in cool summer climates. Elsewhere it is best in part shade (some morning sun). Plants are tolerant of a wide range of soil conditions. Plants perform best in rich, moist, organic soils, with a preference for consistent moisture during the growing season, but plants have tolerance for some dry shade once established. Hardy in zones 3-8.
Growing Instructions for the Blue Plantain Lily
The seeds like moist, well-drained soil. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Peat moss is also a good growing medium for hostas. Put the soil in a pot. Water the mixture so that it is moist but not wet. 2. Put the seeds on the soil. 3. Cover the seeds with a layer of soil that is ¼ of an inch thick. 4. Water the seeds. The soil mixture has to be kept moist for the seeds and seedlings to grow. 5. Place the pots in an area with warm temperatures in full sun or part shade. The seeds germinate in 7-14 days. 6. When the seedlings are a few inches tall, they can be transplanted.
