Wavy Plantain Lily Hosta undulata var. erromena

Water

The Hosta, commonly known as Plantain Lily, should be watered deeply, allowing the soil to become moist but not waterlogged. During the growing season, Hostas typically require about 1 inch of water per week, either through rainfall or manual watering. In hotter climates or during periods of drought, you may need to water the Hosta twice a week to maintain the necessary moisture levels. To ensure optimal growth and health, provide about 1 to 1.5 gallons of water per plant each week, adjusting as necessary based on weather conditions. Avoid overhead watering to prevent leaf burn and fungal diseases; instead, water at the base of the plant to keep the leaves dry.

Light

Hostas, including the Plantain Lily, thrive in light conditions that range from partial to full shade. They prefer a spot that receives morning sunlight with protection from the harsh afternoon sun. The ideal location would offer bright, filtered light, as too much direct sunlight can burn the leaves and cause them to lose their vibrant color. A north-facing garden or an area under the dappled shade of deciduous trees would provide the best light conditions for the Plantain Lily.

Temperature

Plantain Lily grows best in a temperature range of USDA Hardiness Zones 3 through 8, withstanding minimum temperatures of -40 degrees Fahrenheit in the dormant winter months. Preferably, the ideal growing temperatures for the Hosta are between 50 and 75 degrees Fahrenheit. Hostas can suffer in extreme heat, particularly in zones with temperatures consistently above 90 degrees Fahrenheit, causing the leaves to scorch and wilt.

Pruning

Pruning of the Plantain Lily is generally done to remove dead or damaged foliage, which helps maintain the plant's appearance and health. Pruning can be done at any time during the growing season, but it is most commonly performed in late fall after the first frost when the plant goes dormant. Cut back the foliage to the ground to encourage healthy new growth in the spring. Additionally, remove spent flower stalks after blooming to redirect the plant's energy to leaf and root development.

Cleaning

As needed

Soil

The best soil mix for Hosta (Plantain Lily) should be well-draining, rich in organic matter, and have a pH between 6.0 and 7.5. A mix consisting of garden soil, compost, peat moss, and perlite in equal parts works well. Regular replenishing with compost will maintain soil fertility and structure.

Repotting

Hosta (Plantain Lily) generally should be repotted every 3 to 5 years or when it outgrows its container. They can be divided during repotting to manage their size and propagate new plants.

Humidity & Misting

Hosta (Plantain Lily) thrives in moderate humidity levels but is quite adaptable and can tolerate the humidity levels found in most outdoor garden environments without requiring specific adjustments.

Suitable locations

• Indoor

  Keep Hosta in bright, indirect light, ensure high humidity, and avoid dry air.

• Outdoor

  Plant Hosta in shade to partial sun and moist, rich soil.

• Hardiness zone

  3-9 USDA

Life cycle

Hosta undulata var. erromena, commonly known as Hosta 'Undulata', begins its life cycle in the spring as dormant rhizomes or roots that sprout new leaves. These leaves unfurl into the plant's characteristic wavy, variegated foliage, which becomes more pronounced as the plant matures throughout the late spring and summer. During this time, the plant may produce stalks that bear lavender or white flowers, adding to its ornamental value. After flowering, the plant sets seed, which can be dispersed to grow new plants; however, hostas are more commonly propagated by dividing the rhizomes. In autumn, the foliage dies back as the plant enters a dormant period to conserve energy for the winter. The cycle recommences the following spring when temperatures rise and daylight increases.

  Spring-Early Summer

• The Hosta undulata var. erromena, commonly known as Undulata Hosta, is typically propagated by division, which is the most popular method for this plant. The ideal time for dividing hostas is in early spring or fall when the weather is cool, and the plant is not in active growth. To propagate by division, carefully dig up the clump of the hosta making sure to keep as many roots intact as possible. Using a sharp knife or spade, slice the clump into smaller sections, each with at least two or three shoots and an adequate amount of roots. These divisions can then be immediately replanted in prepared soil, ensuring that the crown of the division is at or slightly above soil level. Water the new plantings well to help establish the roots. This method is straightforward and helps maintain the health and vigor of the hosta by rejuvenating older, overcrowded clumps while multiplying the number of plants in the garden.
