How to Grow and Care for the Crownette Plant

The ‘Crownette’ plant is a popular choice for gardeners, known for its distinctive features and ease of care. This resilient perennial offers visual interest, making it a favored addition for both novice and experienced plant enthusiasts. Its striking appearance and low maintenance contribute to its widespread popularity.

Meet the Crownette Plant

‘Crownette’ is a cultivar of Hylotelephium spectabile, also known as Showy Stonecrop or Ice Plant. This succulent perennial originates from China and Korea. It forms an upright, mounding habit, reaching 1 to 2 feet in height and spread.

The plant features thick, fleshy, grey-green to blue-green leaves, which are usually arranged oppositely or in whorls. Its star-shaped flowers, often pink, bloom in dense, flat-topped clusters from late summer through fall, providing nectar for pollinators like bees and butterflies. ‘Crownette’ is hardy in USDA Plant Hardiness Zones 4 to 9.

Essential Crownette Care

Light

‘Crownette’ plants thrive and produce the best blooms in full sun, requiring at least six hours of direct sunlight daily. While they can tolerate some partial shade, too much shade leads to weak, leggy growth and reduced flowering. Adequate light maintains their compact form and ensures vibrant flower development.

Soil

‘Crownette’ prefers well-draining, reasonably fertile soil with a neutral to slightly alkaline pH. Loamy, sandy, or gravelly soils are ideal. Good drainage prevents root rot in overly wet conditions. For heavy clay soil, incorporate well-rotted organic matter to improve drainage.

Watering

‘Crownette’ is drought-tolerant once established, requiring minimal watering. Allow the soil to dry out almost completely between waterings to prevent root rot. Established outdoor plants may only need watering during prolonged dry spells. For potted plants, check the top few inches of soil; water when dry.

Temperature and Humidity

This plant is hardy and tolerant of a wide range of temperatures, withstanding conditions down to approximately -20°C (-4°F). Average humidity levels are sufficient, as it adapts well to both indoor and outdoor environments.

Fertilizing

‘Crownette’ does not require heavy feeding and can suffer in overly fertile soils. A balanced, slow-release fertilizer can be applied sparingly once a month during the growing season. Over-fertilization, especially with high-nitrogen fertilizers, leads to lush foliage but fewer flowers.

Planting Crownette

Select a site that receives full sun, whether in garden beds or containers. Ensure the chosen spot offers excellent drainage. Prepare the planting site by digging a hole twice the width and depth of the root ball. For optimal results, consider amending heavy clay soils with organic matter to enhance drainage.

Remove the plant from its container, loosening any circling roots. Place the plant in the hole so the top of the root ball is level with or slightly above the surrounding soil. Backfill with soil, firming it around the base. Water thoroughly after planting to settle the soil.

Propagating Crownette

Propagating ‘Crownette’ is straightforward using stem cuttings or division. Stem cuttings are best taken in spring or early summer from non-flowering shoots. Snip a 3 to 4-inch stem piece with at least two or three sets of leaves. Remove lower leaves and allow the cut end to callous for a few days before planting in well-draining soil.

Division is another simple method, ideally performed in spring or early summer as new growth begins. Dig up a mature clump and separate it into smaller sections, each with roots and stems. Replant these sections directly into the garden or pot individually.

Addressing Crownette Challenges

‘Crownette’ plants can encounter a few common issues. Aphids and mealybugs are occasional pests found on new growth or undersides of leaves. Inspect plants regularly and treat infestations with insecticidal soap or neem oil.

Fungal problems, such as root and crown rot, occur due to overwatering or poorly draining soil. Proper soil drainage and avoiding excessive moisture prevent these diseases. Leggy growth, characterized by stretched, weak stems, indicates insufficient light; move the plant to a brighter location.
