Description

Description
  • Height and Spread: ‘The King’ can reach heights of up to 6 feet under optimal conditions, making it larger than the typical ostrich fern. Its spread can also be quite expansive, with fronds fanning out to create a substantial presence in the landscape.
  • Leaves: The fronds are deep green, with a distinctive shuttlecock shape that emerges upright in the spring before arching gracefully as they mature. This fern is deciduous, with fronds dying back in the fall to return again in the spring.
  • Growth Habit: It has a clumping growth habit but can spread through underground rhizomes to form large colonies if given space and the right conditions.
Habitat and Cultivation
  • Native Range and Adaptability: While Matteuccia struthiopteris is native to northern and eastern North America, ‘The King’ is a cultivar selected for its size and vigor. It is adaptable to a wide range of climates, hardy in USDA zones 3 through 7.
  • Soil and Sunlight: Prefers consistently moist, fertile soil with a good amount of organic matter. It thrives in partial to full shade, making it an excellent choice for challenging shady areas where other plants might struggle to grow.
  • Watering: Regular watering is crucial to keep the soil consistently moist, particularly in dryer climates or during periods of low rainfall.
Care and Maintenance
  • Pruning: Minimal maintenance is required. Old fronds can be removed in late winter or early spring before new growth starts, to keep the plant looking tidy and to reduce hiding spots for pests.
Landscaping Use
  • Due to its impressive size and beautiful, arching fronds, ‘The King’ is ideally suited as a focal point in shade gardens, alongside streams or ponds, or in naturalized woodland gardens. It can also be used effectively for erosion control on shady slopes.
  • Its lush appearance and ability to form dense colonies make it an excellent choice for creating a green backdrop or as part of a fernery, where its texture and form can be fully appreciated.
