plantain lily 'Blue Cadet'


Hosta 'Blue Cadet' is a herbaceous perennial that is well-regarded for its lush foliage and shade tolerance. This plant has a striking appearance, characterized by its heart-shaped leaves that are noted for their rich blue-green hue. These leaves often have a prominent vein structure and a somewhat puckered texture, giving them a quilted look. The leaves are arranged in a mounded fashion, emerging from the base of the plant and arching outward gracefully. During the blooming period, 'Blue Cadet' produces delicate flower stalks that rise above the foliage. The blooms are bell-shaped and typically come in a shade of lavender, adding a soft, subtle contrast to the bold leaf coloration. These flowers are known to attract pollinators such as bees and hummingbirds to the garden. Over time, the 'Blue Cadet' can form dense clumps, creating an impressive display of color and texture in garden spaces designed for visual interest and low maintenance.

  • water dropWater

    Hostas, including the 'Blue Cadet' variety, prefer evenly moist soil, so it's important to water them thoroughly. On average, provide about an inch of water per week, which translates to about 0.623 gallons for a square foot. During hot or dry periods, you may need to water the plants more frequently, possibly twice a week, to maintain consistent soil moisture. Avoid overhead watering to minimize the risk of leaf diseases; instead, water at the base of the plant early in the day. It’s also beneficial to use mulch to help retain soil moisture and reduce the need for frequent watering.

  • sunLight

    Hostas, such as the 'Blue Cadet', thrive in partial to full shade. The best location is one where morning sunlight may be present, but with protection from the harsh afternoon sun. Dappled shade under trees or a northern exposure often provides ideal light conditions for this perennial to maintain its vibrant foliage and overall health.

  • thermometerTemperature

    'Blue Cadet' hostas grow best in environments where the temperature ranges from 40°F to 85°F. They can survive a minimum temperature down to about 30°F and can handle occasional spikes above 85°F, as long as they are well-watered and not in direct sun. Optimal growth for Hostas typically occurs when temperatures are between 50°F and 75°F.

  • scissorsPruning

    Prune 'Blue Cadet' hostas to remove dead or damaged foliage throughout the growing season as needed to maintain plant health and appearance. Large-scale pruning should happen in the fall after the leaves have died back or in the early spring before new growth starts. Pruning is also an opportunity to control plant size and remove flower stalks after blooms have faded, if desired.

    Hostas prefer moist, well-draining soil with high organic matter. A mix of one part garden soil, one part peat moss, and one part perlite or coarse sand works well for 'Blue Cadet'. The ideal pH for this hosta is between 6.0 and 7.5.

  • plantRepotting

    Hostas like 'Blue Cadet' typically need to be repotted every 3 to 5 years. This allows for refreshing the soil and dividing the plant if it has become too large for its container.

  • circleLife cycle

    Hosta 'Blue Cadet', commonly known as Plantain Lily, begins its life cycle as a dormant rhizome, which is planted in moist, well-drained soil in early spring or fall. In springtime, shoots emerge from the rhizome and develop into a clump of heart-shaped, blue-green leaves that can reach 12 inches in height. Throughout the growing season, the foliage spreads and creates a ground cover; this perennial thrives in partial to full shade. In early to midsummer, the Blue Cadet produces delicate stalks of bell-shaped lavender flowers that rise above the foliage, attracting pollinators. After blooming, the energy is directed back to the rhizome to prepare for dormancy. The plant enters a period of dormancy in the late fall or early winter as the leaves die back, and it remains dormant until the next spring when the cycle begins anew.

      Spring to summer

    • The Hosta 'Blue Cadet', commonly known as the Blue Cadet Hosta, is best propagated through division. This process is ideally carried out in the spring or early fall when the plant is not in active growth. To propagate by division, you should carefully dig up the established clump and use a sharp knife or spade to cut the root mass into smaller sections, each with several shoots and ample root system. These divisions can then be replanted at the same depth they were originally growing, spaced approximately 12 inches (30 centimeters) apart to allow for growth and air circulation. Water the newly planted divisions thoroughly to help establish them. This method of propagation not only helps to create new plants but also rejuvenates older clumps that may have become too dense.
