  • circleLife cycle

    Hosta 'Blue Umbrellas', commonly known as Hosta or Plantain Lily, starts its life as a seed, although garden specimens are often propagated by division. After germination, the plant enters a juvenile phase where it develops a small rosette of leaves close to the ground. As it matures, the rosette enlarges, and the iconic large, heart-shaped, blue-green leaves unfurl, with the plant reaching its full size in several years. Throughout spring and summer, it enters its reproductive stage, sending up tall flower stalks that bear lavender or white bell-shaped flowers, attracting pollinators such as bees. After blooming, seed pods may form and, if not deadheaded, will release seeds before the plant enters dormancy in autumn, with foliage dying back to the ground after the first frost. The life cycle repeats when the Hosta 'Blue Umbrellas' emerges again from its rootstock in the spring.

      Spring to early summer

    • The Hosta 'Blue Umbrellas', known for its large blue-green foliage, can be propagated most effectively through division. The best time for this is in early spring or early fall, when the plant is not in active growth. To propagate by division, carefully dig around the plant taking care not to damage the roots, and lift the entire clump from the ground. Using a sharp spade or knife, divide the clump into smaller sections, ensuring that each division has at least 2-3 shoots and a sufficient root system. Replant the divisions immediately into well-prepared soil, maintaining the same planting depth as before, and water thoroughly to establish the new plants. Over time, these divisions will grow into replicas of the parent plant, exhibiting the same large, textured leaves that make the Hosta 'Blue Umbrellas' a garden favorite.
